Deep Discharging of the Extra Battery
In the interests of best possible battery efficiency, it is recommended that the
battery be deep discharged once a week or so.
To start the deep discharge function, press once the discharge key at the rear
of the charger, whereupon the red indicator showing extra battery charging
starts to flash. Once the battery has been discharged, the charger will automati-
cally start charging it. Should you wish to interrupt discharging, press the dis-
charge key again. The indicator ceases to flash and the charger will resume
battery charging. It is not recommendable to deep discharge a fully charged
battery.
Handsfree Function
When installed in the charging stand, the phone is always in the handsfree
mode of operation. The internal HF speaker and HF microphone are then
activated for the call. It is also possible to turn the phone into HF mode and off
while a call is going on. This is done by removing the phone or placing it on the
charger.
HF speaker volume is adjusted at the phone volume key, and an outgoing call
can be muted by presssing at the mute key on the front edge of the charger.
The muted state is indicated by the message ”MUTED” on the phone display.
Pressing the key once more cancels muting, shown by the text ”UNMUTED”
which appears on the display for a moment.
Using the Voice Mail
The voice–mail key in the middle of the charger is for calling one’s voice mail-
box in the network switching centre and listening to voice messages. When
calling the voice mailbox, the first press on the key makes the call to the
mailbox and the second ends the call.
The Data Connection
The charger contains a 10–pin modular connector for data accessories
(e.g. PCMCIA card).
