Important Notice Concerning the Correct Use and Charging of Ni-MH Batteries
Batteries, due to their construction, undergo some wear and tear. The lifetime of a battery also
depends on correct maintenance. Charging and discharging are the most important factors. You
should take notice of the following to maintain the life of the battery as long as possible.
Ni-MH batteries have a kind of memory, the "memory effect." If fully charged batteries are used
several times only for 15 minutes in the handset and then recharged, the capacity of the batteries will
be reduced to 15 minutes due to the memory effect. Therefore you should discharge the batteries
completely, i.e. use them in the handset until "
them as described in the manual. After the memory effect has occurred, it is possible to achieve
almost complete capacity of the Ni-MH batteries by charging and discharging several times one after
another.
Ni-MH batteries can also self-discharge. This self-discharge depends on the ambient temperature. At
temperatures under 0°C, the self-discharge will be the lowest. High humidity and high temperatures
support the self-discharge. Also long-term storage will lead to self-discharge. A dead Ni-MH battery
should not be disposed of normally. They contain toxic heavy metal hydride and therefore should be
recycled.
Pay special attention to the safety suggestions listed below.
Safety
1) Power source: The AC adaptor should be connected to a power supply only of the type as marked
on the AC adaptor.
2) Non use periods: When the Handset is not being used, turn the power off. When left unused for a
long period of time, the charger should be unplugged from the household AC outlet.
Installation
Environment
1) Water and moisture: Do not use the Handset, the charger and the AC Adaptor near water—for
example, near a bathtub, washbowl, sink, etc. Damp basements should also be avoided.
2) Heat: The Handset, the charger and the AC Adaptor should be kept away from heat sources such
as radiators, kitchen ranges, etc. They also should not be placed in rooms where the temperature
is less than 5ºC or greater than 40ºC.
Placement
1) Stacking: Do not place heavy objects above the Handset and the charger.
2) Foreign material: Care should be taken so that objects do not fall onto and liquids are not spilled
into the Handset and charger. Do not subject the Handset and charger to excessive smoke, dust,
mechanical vibration, or shock.
3) Surface: Place the charger on a flat surface. If the charger is mounted on the wall, install it straight.
