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
