disposed as unsorted waste but must be taken to separate collection at their
end-of-life.
Precautions to Use the Battery
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. You can charge the battery several 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.
Precautions for Safe Usage
Ensure to follow the following precautions related to battery usage.
1. Do not disassemble or open, crush, bend or deform, puncture or shred.
2. Do not modify or remanufacture, attempt to insert foreign objects into the battery,
immerse or expose to water or other liquids, expose to fire, explosion or other hazard.
3. Only use the battery with a charging system that has been qualified with the system per
this standard. Use of an unqualified battery or charger may present a risk of fire,
explosion, leakage, or other hazard.
4. Do not short circuit a battery or allow metallic conductive objects to contact battery
terminals.
General Information 9
5. Replace the battery only with another battery that has been qualified with the system per
this standard, IEEE-Std-1725.
6. Promptly dispose of used batteries in accordance with local regulations.
7. Battery usage by children should be supervised.
8. Avoid dropping the phone or battery. If the phone or battery is dropped, especially on a
hard surface, and the user suspects damage, take it to a service center for inspection.
9. Improper battery use may result in a fire, explosion or other hazard.
10. The phone shall only be connected to CTIA certified adapters and products that bear the
USB-IF logo or have completed the USB-IF compliance program.
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 the 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.
General Information 10
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 when required, especially when posted in hospitals and
airplanes. 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 XP STRIKE 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 NonIonizing 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.
General Information 11
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 SONXP3410 phone when tested by Sonim for use:
● By the head is 1.39 W/kg (1 g).
● Worn on the body is: 0.499 W/kg (1 g).
For body-worn operation, this phone meets FCC RF exposure guidelines provided that it is used
with a non-metallic accessory with the handset at least 2.5 cm from the body. Use of other
accessories may not ensure compliance with FCC RF exposure guidelines.
