Intercoms in a Press Box during a game or practice, you must ensure 

that A) You turn on these Intercoms first, and B) that you only use them 

in the Press Box during said game/practice. Failure to do so may cause 

temporary loss of communication.

NOTE:  Each additional MULTIVOICE Intercom will be connected 

to the other units in your system as soon as you complete the 

steps in Section #1 above.

NOTE:   If one of the Channel LED Lights are lit on your MULTIVOICE 

Intercom, you will hear everyone speaking on that particular Channel. 

If you want to BE HEARD

LED Lights on the front of your Intercom must also be lit. To enter Talk 

Mode, please push the mic button, flip the switch on the Switch-to-Talk 

box, or lower your boom mic so it is positioned in front of your mouth; 

the Blue LEDs will light-up and you can now BE HEARD. To deactivate 

your mic and return to Listen Mode, push the mic button or lift your 

boom mic; the Blue LED Lights will now turn off.

NOTE:  MULTIVOICE Intercoms come standard with 4-6 

Channels, (4 channels for MV-AUDIBLE and 6 channels for 

MV-NEXUS and MV-PROTECTOR) with each Channel LED Light 

signifying the respective Channel, starting (from Left to Right) 

with Channel #1 and ending with Channel #4 for MV-AUDIBLE 

and Channel #6 for MV-NEXUS and MV-PROTECTOR. To change 

from one Channel to the next, simply push the Channel Button 

once. (See section #7 on the back page for more info.)
