General Information 10
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.
