Intercom function not working between keypads.

I purchased a minderpro with the cbus 5305 ucm 2xLCD Keypads. Cannot get the intercom function to work between the 2 keypads.

The intercom between keypads is activated by pressing F8 on one keypad
This broadcasts the voice on the initiaing keypad to all other keypads, ie in your case the other one
The other keypads can only listen. To talk press a key on that keypad to switch directions. This intercom is one way only, and is used to call or look for someone elsewhere in the premises

The keypad to door station and phone to keypad and door stations work differently, in duplex mode
