to enable you to operate your phone safely and conform to any legal requirements regarding the use of cellular phones.
Do not to use the phone at a refuelling point. Observe restrictions when using radio equipment at 
fuel depots, chemical plants or where blasting operations are in progress.
Electrical interference may obstruct the use of your phone. Observe restrictions in hospitals and 
near medical equipment.
Switch off your cellular phone when in an aircraft. Wireless phones can cause interference or danger 
to an aircraft. In an aircraft, the phone can be used in flight mode.
Do not expose the battery to high temperatures (in excess of 60°C).
Adhere to road safety laws. Do not hold/use a phone while you are driving; find a safe place to stop 
first. Do not speak into a hands-free microphone while you are driving.
Avoid using the phone in close proximity to personal medical devices, such as pacemakers and 
hearing aids. 
Use only Sonim XP3405 SHIELD approved charging equipment to charge your phone and avoid 
damage to your phone.
The symbol of the crossed-out wheeled bin indicates that this product, and any enhancements 
marked with this symbol, can not be disposed as unsorted waste but must be taken to separate 
collection at their end-of-life.
Your Safety Guidelines

Ensure that only qualied personnel install or repair your phone.
The Sonim XP3405 SHIELD 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 signicant drop in temperature. This does not indicate water leakage. The droplets will 
disappear at room temperature.
The Sonim XP3405 SHIELD 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 XP3405 SHIELD from salt water, dust and strong impacts.
Make back-up copies of important information stored in your phone or maintain a written record.
Your Safety Guidelines

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 rst 
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 re 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 
Your Safety Guidelines

11
Your Safety Guidelines
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 ammable 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 XP3405 SHIELD 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 Specic 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 scientic 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 certied 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 certied 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 XP3400-A-R4 
phone when tested by Sonim for use:
•  By the ear is TBD W/kg (1 g).
•  Worn on the body is TBD W/kg (1 g).
For body-worn operation, this phone meets FCC RF 

12
Your Safety Guidelines
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.

Our Warranty
Subject to the conditions of this Comprehensive 3 year

the time of its original purchase by a consumer, and for a 
subsequent period of Three (3) years.

Phone Care
The Sonim XP3405 SHIELD is designated class IP68 for 
dust and water protection, according to the IEC Ingress 
Protection (IP) Standard 60529. This means that the 
phone is dust protected and can be submerged into 2m 
deep water for up to 30 minutes. Immersion in deeper 
water can damage it and must be avoided. 
The Sonim XP3405 SHIELD is solid and built for heavy 
duty use. Its design protects against disassembly or 
mechanical damage when subjected to forces equal to 
free fall from the height of 2 meters. Subjecting the phone 
to stronger impact and forces can damage it and must be 
avoided.
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. Nor does this warranty 
cover any failure of the Product due to software or 
hardware modication 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.

authorised person. Tampering with any of the seals

6.  The warranty does not cover Product failures which 
have been caused by use of accessories or other 
peripheral devices which are not Sonim branded 
original accessories intended for use with the 
Product.
7.  The 3 year warranty does not cover battery,
