CALL DETECT trimmer (R29)

With this trimmer the CALL detect level can be

adjusted. Proceed as follows:

• Set the TX CONTROL select switch at the

front panel in the position CALL

• Connect a user station to the intercom

party line

• Press and hold a CALL button on that user

station

• Turn trimmer R29. If the trimmer is turned

too much counter clockwise the internal

Transmit Switch is triggered every second

(this is also shown by the Rx/Tx LED).

f the trimmer is turned too much clockwise

the internal Transmit Switch has a very

long release time when the CALL button of

the connected station is released. Try to

find a suitable position for the trimmer in

between those two points.
