3.4 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.
3.5 Charging the Batteries
Charge the batteries approximately 6 to 7 hours before using the phone. This protective measure extends the service life
of the batteries.
The maximum power output is only attained after three to five charge and discharge cycles.
When replacing the batteries, ensure the correct polarity. Use only re-chargeable AAA NiMh battery of 800 mAh, 1.2V.
The manufacturer does not accept liability for malfunctions or damage caused by using other battery types or normal
batteries.
Charging and Operating Times
· Charging time: (empty batteries) to full capacity in approximately six to seven hours.
· Talk time: approximately 10 hours (with fully charged batteries).
· Standby time: up to 100 hours (with fully charged batteries).
Charge Display
The charge status of the batteries is indicated on the display. This means:
batteries fully charged (80 – 100 %)
batteries 60 – 79 %
batteries 40 – 59 %
batteries 20 – 39 %
batteries 0 – 19 %
(frame flashes) batteries are empty: an alert tone is also given.
Battery Capacity Icon
When batteries are replaced, no icon will be displayed before a charging cycle has been completed, except when almost
empty batteries are inserted in the phone, then the icon will be shown immediately.
When the battery capacity icon is displayed, the indication is reliable.
If the charged batteries are inserted, the batteries can become hot during the first charge cycle, and if the fully charged
batteries are removed from the phone and inserted again, the batteries can become overcharged.
Charge Warning
When the batteries’ capacity is almost exhausted, an acoustic warning is given in the form of 3 short ”beep” signals (only
during a call). Upon receiving the beep approximately 5 minutes of talk time is left.
