In the switched-on condition, the battery symbol is always visible on the display and indicates the still

available amount of energy. The operating period can amount to up to approx. 3000 hours dependent on

the power supply source and the programmed operating mode. When the energy source is completely

exhausted, the empty battery symbol blinks continuously and simultaneously a regular clicking sound is

audible. In this condition, an operating time of at least 24 hours is still available. By pushing the confirma-

tion key, the battery alarm is switched off, the empty battery symbol, however, continues to blink.

Changing the Power Source

Open the housing cover on the rear side of the receiver. Insert the power source supplied into the com-

partment and in doing so pay attention to the correct polarity.

The following power sources of the size AA, resp., L6, or AM3 (Mignon) can be used:

• Alkaline: Leak-proof Alkaline – dry batteries. Attention: These must not be charged or recharged!

charging, for safety reasons please only utilise a charging unit from the original SWISSPHONE –ac-

cessories range for the SWISSPHONE DE900 receiver.
