Energy management
The power consumption of this radio set is very small. If no signal is received, the electronic
battery stand-by mode is activated. If the capacity of the battery pack is too low or if the
batteries are empty, the radio set will emit an audio warning that is repeated every 15 sec.
Now you have to charge the battery pack or replace the batteries.
If the battery stand-by mode is activated the transmission/
reception LED emits red light in intervals of 2 sec.
Attach/take off belt clip
Place the grooves of the belt clip on the guide rails on the upper
part of the housing and slide the clip downwards until the safety
catch snaps in (see figure 3).
Push the safety catch (on top of the belt clip) away from the
housing in order to remove it from the radio set (see figure 4).

adopt the last setting.
