3 Operation
3.1 Talk
3.1.1 Talk key properties
The Talk keys have touch and latch functions. Pressing the key briefly represents the latch function for switching on and
off. If the key is held down for a longer period, the touch function will be activated. In this case, the Talk function will be
active for as long as the key is held down.
3.1.2 Talking to intercom channels
There are two Talk keys, one for each intercom channel. They are marked “I“ and “II“. Press Talk key “I” to talk to
intercom channel I. The active Talk function is indicated by the corresponding LED.
Talk I active
3.2 Listen
A volume control is provided for each channel on the right-hand side of the unit. The top one controls the volume of
Channel 1 and the bottom one the volume of Channel 2. To increase the volume, rotate the knob clockwise.
Note: If the headset is put down and the Talk function is active, depending on the volume of the headset, feedback
can occur. Therefore, before putting the headset down, always switch off the Talk function. Activated Talk keys can be
switched off remotely using the “Mic Kill” function on the MS-2004 and MS-2002 master stations.
3.3 Call Light
3.3.1 Sending a call light signal
You can only send a call light signal to a channel where the Talk function has been activated. If the channel is
switched to “Talk”, the corresponding LED indicator lights up. By pressing the call light key marked “L”, the call light
signal is allocated to the channel with the Talk function preselected and sent to it. The call light illuminates on all
beltpacks in the party line unless it has been suppressed by beltpack-setup. Your own call light will also be illuminated
for the duration of the call.
