Installation and User Instructions

2.2.4 Headset/Volume control (4)

This 6-pin connector provides the connection to the

headset and the volume control. This volume control

also controls the volume of the loudspeaker connected

to connection 3.

A logarithmic potentionmeter R (typical value: 100

kohm) is used to attenuate the audio signal.

If a volume control is not needed, pin 3 and 4 must be

connected to each other. The volume level of the

earphone or loudspeaker is then at its maximum.

Warning

Do not connect DC or AC signals to the control

inputs, otherwise the input circuit may be

damaged. Only use voltage-free contacts.

Note

Do not combine control input wires of multiple

control inputs (e.g. do not use a common return

wire).
