Important Battery Information
Only use re-chargeable AAA NiMh battery of typical 800 mAh, 1.2 V. Never use a battery which
is damaged or worn out.
Heat or cold reduces the performance and life of the batteries. It is possible that a phone with hot
or cold batteries can be temporarily out of operation even if the batteries are fully charged.
Used batteries should be disposed of in accordance with local authority regulations.
Do not throw batteries in a fire.
Charging and Discharging
The batteries can be charged and discharged hundreds of times, but sooner or later they will be
worn out. If the operating time (i.e. talk and standby time) is significantly shorter than usual, then
it is time to replace the batteries.
To maintain optimum operating time, the batteries should be discharged from time to time by not
placing the phone in the charger but leaving it switched on until it switches itself off. Only use this
method to discharge the batteries.
Extreme temperatures influence the charging capability of the batteries.
