To call a channel:

Press the CALL button; the CALL LED’s will flash to indicate “call signal ready”.

Press and hold the talk button for the channel to be called; the call signal will be transmitted as 
long as the talk button is held.

When a response is received, release the talk button to turn off the call signal.

Receiving a call:

When there is an incoming call, the indicator LED above the appropriate channel selector button 
will flash.

The talk-off feature deactivates the mic switches of all remote user stations on a selected channel. 
To use talk-off:

Press and release the CALL button three times in rapid succession; the CALL LED’s will turn 
on to indicate “talk-off signal ready”.

Momentarily press the talk button for the channel to be deactivated. This will cause the talk-off 
signal to be transmitted.

Release the talk button to end the talk-off signal transmission.

Press and hold the CALL button for 5 seconds: the TALK 1, LISTEN 1, TALK 2, LISTEN 2, 
PANEL MIC, SPKR ON, and MIC ON LED’s will begin to flash. This is the main menu.

The submenu names are listed under the switches. Press the desired switch to access the submenu 
for that switch. Press the CALL button from a submenu to return to the main menu; press the 
CALL button again to exit from the main menu to the operating mode.

NOTE

If no submenu is selected from the main menu within 12 seconds after program mode activation, 
the programming mode will time out, and the MCE325 will return to normal operation. If a 
submenu is selected, however, the unit will remain in programming mode until intentionally 
exited.

The following paragraphs describe each of the submenus. The default, or factory pre-programmed 
setting, is also indicated for each submenu.
