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.
Installations
Environment
1) Water and moisture: Do not use the Handset and the charger near water—for example, near a
bathtub, washbowl, sink, etc. Damp basements should also be avoided.
2) Heat: The Handset and the charger 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 5
ºC or greater than 40 ºC.
Placement
1) Stacking: Do not place heavy objects on top of 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.
For Best Performance
Operating Range
1) The range of operation depends on the topography of your office, weather or usage conditions,
because signals are transmitted between the Cell Station (CS) and the Handset by radio waves.
2) Normally, you get greater range outdoors than indoors. If there are obstacles such as walls, noise
may interfere with your telephone calls. In particular, high metal shelves or reinforced concrete
walls will restrict your operating range.
3) A Handset may not work when it is too far from the CS depending on the structure of the building.
Noise
Occasional noise or interference may occur due to electromagnetic radiation from objects such as
refrigerators, microwave ovens, faxes, TVs, radios, or personal computers. If noise disturbs your
telephone calls, keep the Handset away from these electrical appliances.
