1. No call tone or LED when sub calls
master (2-wire connection).
Make sure jumper is installed between E and - at the subs and the master
station.
2. Call tone works, but no
communication, or communication
works, but no call tone.
Same as #1, E & - jumper must be in place. If 3 wires are used, 1 & - are for

3. Master stations cannot call each
other.
The “C” terminal of the master means “CALL”, and allows master-to-master
communication. Make sure the “C” terminal of each master is connected to
a designated # terminal on all other masters, (example: C at ma.ster 1
connects to the “1” teminal of all other masters.)
4. Cali tone is too loud or too soft.
Adjust call tone volume with slide switch located under faceplate. (Use small
screwdriver.)
