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.)
