Appendix
Always switch the handset off before removing the batteries, as otherwise data could be lost.
1. Use only nickel metal hydride (NiMH) rechargeable batteries.The talk times, standby times, and
charging times stated below (see the section entitled "Technical Data") only apply when batter-
ies with a capacity of 700 mAh are used.Three size AAA NiMH rechargeable batteries are
included in the original product package.
Note
Never use nonrechargeable batteries, fuel cells, or other types of rechargeable battery. This is
dangerous, and could also lead to malfunctioning or damage to your equipment.
The manufacturer will not accept any liability in such cases.
2. Rechargeable batteries warm up during the charging process. This is normal and not dangerous.
3. Never use other manufacturers' charger cradles, as this could damage the batteries.
4. Be careful to observe the correct polarity when replacing the batteries.
5. Never put a battery in water or throw a battery into a fire.
6. Never forcibly open a battery, as this could allow battery acid to leak out and cause injury.
7. The battery charge level indicator requires a number of charge/discharge cycles to have taken
place before it can accurately reflect the charge level of new batteries.
8. New batteries only reach their full capacity after a number of charge/discharge cycles.
9. You can replace your handset in the charger cradle or the base station after every call if you
wish. The charging process is electronically regulated so that the batteries are always optimally
recharged, whatever their charge level at the time. Do not remove the batteries from the hand-
set unless there is a good reason for doing so. Removing the batteries interrupts the optimized
recharging process.
The capacity of the batteries can be increased by discharging them completely in the handset
when they have been in use for a long period, and full recharging them again.
10. Never short-circuit a battery — this is dangerous! Avoid accidental short circuits when trans-
porting the equipment or storing it together with bunches of keys, metal plates, or similar
objects. Avoid getting fatty substances on the batteries by keeping them properly packed when
not in the handset. Also avoid getting fatty substances on the handset contacts.
