Desktop charger for Cordless DT412/DT422
The desktop charger is used for charging your Cordless, but also
for storing it when you are placed at one location, for example at
your desk.The tilted design facilitates the use of handsfree
operation, i.e. in loudspeaking mode. The charger is delivered with
a plug-in power supply and is connected into an ordinary wall
socket.
Charging rack
Note: See also separate Installation Guide, supplied
together with your Cordless.
The charging rack is used for charging your Cordless and/or spare
batteries. When charging spare batteries an adapter is needed. The
wall mounted charging rack and its power supply are a modular
system which enables a number of installation configurations.
Each power supply can support several charging racks with four
positions for Cordless phones and/or batteries in each rack (see
technical specifications for the charging rack).
As the Cordless cannot distinguish between a desktop charger and
the charging rack, it is recommended that the alert signal is
silenced when placed in a rack, see section “Audible Adjustments”
on page 99. There is also a SIM parameter that can be set in the
SIM card programmer by your system administrator.
