Appendix
Guidelines to Lithium Batteries
Initial Use
The lithium ion battery in your device is warranted for 6 months from date of purchase. While
these batteries require no special attention, following the recommendations in this appendix
should extend the useful service life and safety.
Fully discharging and recharging of a new battery may be beneficial in calibrating the battery.
Use
Always keep the batteries at room temperature; exposing the battery to elevated temperature,
such as in window or car windshield in direct sunlight, will shorten the batteries useful life span
and may cause damage. The batteries should not be operated below 0°C or above 40°C. Use
only the charger(s) provided with the handset to charge the batteries.
Do not:
short circuit, over-charge or over-discharge the batteries
attempt to disassemble batteries
pierce the batteries with nail or other sharp object
immerse the batteries in water or expose the batteries to moisture,
strike, throw or subject the batteries to severe physical shock
solder directly on the terminals of the batteries.
Any of the above will invalidate the warranty.
NOTE
The battery compartment contains a Liquid Contact Indicator, which, when exposed to water or
a liquid containing water, will turn from white to red and will invalidate the warranty.
When the battery is discharged, recharge the battery as soon as possible. If the battery is left in
a discharged state for an extended period, it may not be possible to recharge the battery.
Keeping the battery in the constant charging mode for an extended period will shorten its life,
and may cause the battery to deform.
Avoid frequent full discharges of the batteries. Fully discharge the batteries only after 25-30
