4.1 Microphone amplification
The CT-MultiCom recognizes the connected headset and adjusts the microphone amplification

On radios, the accessory interface of which is alive even in switched-off condition (e.g. STP
8000), disconnect the plug of the CT-MultiCom from the radio or remove the storage battery
from the radio.

Press the button (fig. 2/b) and while holding it down switch the radio ON. On radios, the
accessory interface of which is alive even in switched-off condition (e.g. STP 8000), reconnect
the plug of the CT-MultiCom or reinsert the storage battery and continue holding the button
down until the LED flash up 3 times and you hear the audio signals.

Let the button (fig. 2/b) go.

To increase microphone amplification press the button (fig. 2/b); each keystroke is
acknowledged by an audio signal and one Green LED flashing; reaching maximum volume is
followed by a double audio signal and two flash ups of the LED.

To reduce microphone amplification press the button (fig. 2/c); each keystroke is acknowledged
by one audio signal and one Red LED signal; reaching minimum volume is acknowledged by a
double audio signal and two flash ups of the LED.
Store the microphone amplification by switching the connected radio briefly OFF and ON again. On
radios, the accessory interface of which is alive even in switched-off condition (e.g. STP 8000), store
this setting by briefly pulling the CT-MultiCom plug off the radio or by disconnecting the storage battery
