The antenna(s) used for this transmitter must not be
co-located or operating in conjunction with any other
antenna or transmitter.
The country code selection is for non-US model
only and is not available to all US model. Per
FCC regulation, all WiFi product marketed in US
must be fixed to US operation channels only.
RF Exposure Information (SAR)
This device meets the government’s requirements
for exposure to radio waves. This device is designed
and manufactured not to exceed the emission limits
for exposure to radio frequency (RF) energy set by
the Federal Communications Commission of the U.S.
Government.
The exposure standard for wireless device employs a
unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit set by the FCC is 1.6W/
kg. *Tests for SAR are conducted using standard
operating positions accepted by the FCC with the device
transmitting at its highest certified power level in all
tested frequency bands. Although the SAR is determined
at the highest certified power level, the actual SAR level
of the device while operating can be well below the
maximum value. This is because the device is designed
to operate at multiple power levels so as to use only
the poser required to reach the network. In general, the
closer you are to a wireless base station antenna, the
lower the power output.
The highest SAR value for the model device as reported
to the FCC when tested for use at the ear is 0.38 W/
kg and when worn on the body, as described in this
user guide, is 0.56 W/kg (Body-worn measurements
differ among device models, depending upon available
accessories and FCC requirements.)
While there may be differences between the SAR levels of
various devices and at various positions, they all meet the
government requirement.
The FCC has granted an Equipment Authorization for
this model device with all reported SAR levels evaluated
as in compliance with the FCC RF exposure guidelines.
SAR information on this model device is on file with the
FCC and can be found under the Display Grant section
of www.fcc.gov/oet/ea/fccid after searching on FCC ID:
WYPC21F007AC.
For body worn operation, this device has been tested
and meets the FCC RF exposure guidelines for use with
an accessory that contains no metal and be positioned
a minimum of 1.5 cm from the body. Use of other
accessories may not ensure compliance with FCC RF
exposure guidelines. If you do not use a body-worn
accessory and are not holding the device at the ear,
position the handset a minimum of 20 cm from your body
when the device is switched on.

Ensure that only qualified personnel install or repair your phone.
The Sonim Enduro is water-proof and can be submerged to 2 metres for 30 minutes.
• Ensure to properly close the rubber cover of the charging connector and audio connector, to
avoid deposits of water drops on these connectors, when the phone is immersed in water.
• Water droplets may condense under the display cover if the phone is immersed in water
with significant drop in temperature. This does not indicate water leakage. The droplets will
disappear at room temperature.
The Sonim Enduro is dust-resistant, rugged and shock-resistant. However, it is not dust-proof
or unbreakable if subjected to overwhelming impact. For best results and long product life, one
should protect the Sonim Enduro from salt water, dust and strong impacts.
Make back-up copies of important information stored in your phone or maintain a written record.

Battery Performance
A rechargeable battery powers your device. Use the
battery only for its intended purpose. Never use any
charger or battery that is damaged. If the battery is
completely discharged, it may take a few minutes before
the charging indicator appears on the display or before
any calls can be made. The full performance of a new
battery is achieved only after three to four complete
charge and discharge cycles. The battery can be charged
and discharged hundreds of times but it will eventually
wear out. Unplug the charger from the electrical plug and
the device when not in use. Ensure that you do not leave
the fully charged battery connected to a charger. If left
unused, a fully charged battery will lose its charge over
time.
Battery Replacement
When the talk and standby times are noticeably shorter
than normal, replace the battery with an original Sonim
battery. If a replacement battery is being used for the first
time or if the battery has not been used for a prolonged
period, it may be necessary to connect the charger and
then disconnect and reconnect it to begin charging the
battery.
Avoid Short Circuit
Do not short-circuit the battery. An accidental short-
circuit can occur when a metallic object such as a coin,
clip, or pen causes direct connection of the positive (+)
and negative (-) terminals of the battery. (These look
like metal strips on the battery.) This might happen, for
example, when you carry a spare battery in your pocket
or purse. A short-circuit at the terminals may damage the
battery or the connecting object.
Avoid High Temperatures
If you leave the battery in hot or cold places, such as
in a closed car in summer or winter conditions, it will
reduce the capacity and lifetime of the battery. For best
results, try to keep the battery between -20°C and +55°C
(-4°F and 131°F). A device with a hot or cold battery
may not work temporarily, even when the battery is fully
charged. Battery performance is particularly limited in
temperatures well below freezing.
Battery Disposal
Do not dispose off batteries in a fire as they may explode.
Batteries may also explode if damaged. Dispose of
batteries according to local regulations and recycle when
possible. Do not dispose as household waste. Do not
dismantle, open or shred cells or batteries. In the event of
a battery leak, do not allow the liquid to come in contact
with the skin or eyes. In the event of leak or a hazard
seek medical help immediately.
Personal Medical Devices
Mobile phones may affect the operation of cardiac
pacemakers and other implanted equipment. Please
avoid placing the mobile phone over the pacemaker, for
example in your breast pocket. When using the mobile
phone, place it at the ear opposite the pacemaker. If a
minimum distance of 15 cm (6 inches) is kept between
the mobile phone and the pacemaker, the risk of
interference is limited. If you suspect that interference
is taking place, immediately turn off your mobile phone.
Contact your cardiologist for more information. For
other medical devices, consult your physician and the
manufacturer of the device. Comply with instructions to
switch off the device or deactivate the RF transmitter

11
When required, especially when posted in hospitals and
aeroplanes. Equipment used in these places may be
sensitive to radio waves emitted from the device and
adversely affect their operation. Also, observe restrictions
at gas stations or other areas with flammable atmosphere
or when close to electro-explosive devices.
Child Safety
Do not allow children to play with your mobile phone or
its accessories. Keep it out of their reach. They could
hurt themselves or others, or could accidentally damage
the mobile phone or accessories. Your mobile phone and
its accessories may contain small parts, which could be
detached and create a choking hazard.
Emergency Calls
Mobile phones operate using radio signals, which cannot
guarantee connection under all conditions. Therefore
you should never rely solely upon any mobile phone for
essential communications (e.g. medical emergencies).
Emergency calls may not be possible in all areas, on all
cellular networks, or when certain network services and/
or mobile phone features are in use. Check with your
local service provider.
SAR Information
The Sonim Enduro has been certified in compliance
with the Government’s requirements for exposure to
Radio Waves.
When communicating over the wireless network, the
mobile phone emits via the radio frequency waves low
levels of radio energy. The Specific Absorption Rate, or
SAR, is the amount of RF energy absorbed by the body
while using the phone and is expressed in watts/kilogram
(W/kg).
Governments around the world have adopted
comprehensive international safety guidelines, developed
by scientific organizations, for example, ICNIRP
(International Commission on Non-Ionizing Radiation
Protection) and IEEE (The Institute of Electrical and
Electronics Engineers Inc.). These guidelines establish
permitted levels of radio wave exposure for the general
population.
Tests for SAR are conducted using standardized methods
with the phone transmitting at its highest certified power
level in all used frequency bands.
SAR Data Information for residents in the United
States and Canada.
In the United States and Canada, the SAR limit for
mobile phones used by the public is 1.6 watts/kilogram
averaged over one gram of tissue. The standard
incorporates a margin of safety to give additional
protection for the public and to account for any variations
in measurements.
Before a phone model is available for sale to the public
in the US, it must be tested and certified by the Federal
Communications Commission (FCC) that it does not
exceed the limit established by the government-adopted
requirement for safe exposure. The tests are performed
in positions and locations (that is, by the ear and worn on
the body) as required by the FCC for each model.
The highest SAR value for the Sonim XP4400-A-R1
phone when tested by Sonim for use:
• By the ear is 0.38 W/kg (1 g).
• Worn on the body is 0.56 W/kg (1 g).
For body-worn operation, this phone meets FCC RF

12
exposure guidelines provided that it is used with a non-
metallic accessory with the handset at least 1.5 cm from
the body, or with the original Sonim accessory intended
for this phone and worn on the body. Use of other
accessories may not ensure compliance with FCC RF
exposure guidelines.
HAC Rating
The FCC has created a rating system for cellular phones
regarding their HAC-related performance. This rating
helps consumers with hearing disabilities to find phones
that will work well with their hearing aid devices. The
HAC rating and measurement procedure are described
in the American National Standards Institute (ANSI)
C63.19:2007.
ANSI C63.19 contains two rating standards: an “M” rating
from 1 to 4 for hearing aids operating in microphone
mode, and a “T” rating from 1 to 4 for hearing aids
operating in telecoil mode.
M-Rating stands for Microphone rating and indicates
the amount of reduction of RF interference between the
telephone and the hearing aid in acoustic coupling mode
(also called microphone mode).
Phones rated M3 or M4 meet FCC requirements and
generate less interference to hearing devices set in
microphone mode.T-Rating stands for Telecoil rating and
represents inductive coupling with hearing aids that are
operating in telecoil mode. A telecoil is a small piece of
tightly wrapped wire, built into some hearing aids. While
the microphone of a hearing aid picks up all sounds, the
telecoil will only pick up an electromagnetic signal from
the telephone. Thus, users of telecoil-equipped hearing
aids are able to communicate over the telephone without
the amplification of unwanted background noise.
Phones rated T3 or T4 meet FCC requirements and
generate less interference to hearing devices set in
telecoil mode.
A combination of M-rating and T-rating defines the
final HAC rating and is a deciding factor in selecting
cellular phones for people with hearing problems. A HAC
compliant phone could be rated:
• M3/T3
• M3/T4
• M4/T3
• M4/T4
These ratings assist hearing device users to find
phones that are compatible with their hearing devices.
Ratings are shown on the phone’s box or label. The
ratings are not guaranteed for suitability. The results
vary depending on the individual’s hearing loss and the
immunity characteristics of the used hearing device, i.e.
its resistance to interference. The best way to evaluate
the suitability of the phone is to try it with the intended
hearing aid device.
Sonim XP4400-A-R1 has been tested for hearing aid
device compatibility and complies with the Federal
Communications Commission (FCC) requirements. Sonim
XP4400-A-R1 is rated M3/T4.

Our Warranty
Subject to the conditions of this limited 2 year Warranty
Sonim warrants this product to be free from major
defects in design, material and workmanship at the
time of its original purchase by a consumer, and for a
subsequent period of Two (2) years.
What We Will Do
If during the guarantee period, this product fails to
operate under normal use and service, due to defects
in design, material or workmanship, Sonim’s authorised
distributors or service partners, in the country/region
where you purchased the product, will repair or replace
at the sole discretion of Sonim, with the same or better
model in the same or better condition. Sonim and its
service partners reserve the right to charge a handling fee
if a returned product is found not to be under warranty
according to the conditions below.
Please note that some of your personal settings,
downloads or other information may be lost when your
Sonim Product is repaired or replaced. Sonim does not
take any responsibility for any lost information of any kind
and will not reimburse you for any such loss.

65
You should always make backup copies of all the
information stored on your Sonim Product such as
downloads, calendar and contacts before handing in your
Sonim Product for repair or replacement.
Phone Care
Each Sonim Phone has a designated IP class for dust
and water protection, according to the IEC Ingress
Protection (IP) Standard 60529. Your device is water and
dust resistant in compliance with the Ingress Protection
rating IP54. This means that the phone is protected
against dust and water sprayed from all directions.
Liquids can cause serious damage to the device. Water
damage can void your manufacturer’s warranty.
Sonim phones are built for heavy usage. Its design
protects against disassembly or mechanical damage
when subjected to forces equal to free fall from the height
of 4 feet onto plywood.
Conditions
1. The warranty is valid only if the product has been
registered within 30 days of date of purchase, and
sonim reserves the right to refuse warranty service
otherwise.
2. Should the phone not be registered, the warranty is
valid only if the original proof of purchase issued to
the original purchaser by a Sonim authorised dealer,
specifying the date of purchase and serial number
for this Product, is presented with the Product to
be repaired or replaced. Sonim reserves the right to
refuse warranty service if this information has been
removed or changed after the original purchase of
the Product from the dealer.
3. If Sonim repairs or replaces the Product, the
repaired or replaced Product shall be warranted
for the remaining time of the original warranty
period or for ninety (90) days from the date of
repair, whichever is longer. Repair or replacement
may involve the use of functionally equivalent
reconditioned units. Replaced parts or components
will become the property of Sonim.
4. This warranty does not cover any failure of the
Product due to normal wear and tear, or due to
misuse or abuse, including but not limited to use
in other than the normal and customary manner,
in accordance with the Sonim instructions for
use and maintenance of the Product, including
liquid damage, exposure to solvents or any other
internal liquid damage caused by misuse or not
closing covers. Nor does this warranty cover any
failure of the Product due to software or hardware
modification or adjustment, acts of God or damage
resulting from liquid interacting with the product
beyond what is described as acceptable in the
user guide for the product. A rechargeable battery
can be charged and discharged hundreds of times.
However, it will eventually wear out - this is not
a defect. When the talk-time or standby time is
noticeably shorter, it is time to replace your battery.
Sonim recommends that you use only batteries and
chargers approved by Sonim. Minor variations in
display brightness and colour may occur between
phones. There may be tiny bright or dark dots on
the display. These are called defective pixels and
occur when individual dots have malfunctioned and
can not be adjusted. Several defective pixels are
deemed acceptable.

66
5. This warranty does not cover Product failures
caused by installations, modifications, or repair or
opening of the Product performed by a non-Sonim
authorised person. Tampering with any of the seals
on the Product will void the warranty.
6. The warranty does not cover Product failures which
have been caused by use of accessories or other
peripheral devices that are not Sonim branded and
tested original accessories intended for use with the
Product.
7. The 2 year limited warranty does not cover battery,
accessories or any 3rd party SW applications, which
are instead covered to the extent provided by the
original vendor guarantee for these products.
8. THERE ARE NO EXPRESS WARRANTIES,
WHETHER WRITTEN OR ORAL, OTHER THAN
THIS PRINTED LIMITED WARRANTY. ALL
IMPLIED WARRANTIES, INCLUDING WITHOUT
LIMITATION THE IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE, ARE LIMITED TO THE
DURATION OF THIS LIMITED WARRANTY. IN NO
