Power Supply Connector

Align and insert the external power supply connector. Tighten the locking ring. Connect a power cord to the power supply and

to an AC power source. The power supply accepts 100-240 VAC, 50/60 Hz.

At power-up, the alphanumeric displays will first show asterisks (******). After several seconds to a minute the intercom key

assignments will display.

NOTE: If the keypanel cannot establish communication with the intercom system, all alphanumeric displays will

continue to show asterisks. Check the keypanel to matrix cable connection if this occurs. If the keypanel loses

communications with the intercom, it will not revert to ****’s for 30 seconds. Hence, if there is a short disruption

the data communications, the panel will not show ******’s at all (although the panel my briefly display ------’s).

Headset Connector

A stereo headset may be connected for use along with or in place of the front panel speaker and a separate microphone.

Headphones may be connected for use with a separate microphone.

Headset Microphone Gain Adjustment

The gain of the headset microphone preamp output to the matrix can be adjusted via the recessed trim pot located on the back

panel. Turn the pot clockwise to increase gain and counter-clockwise to decrease gain. The trim pot provides 40dB of

adjustment range with a +16dBu maximum output limit. The default factory default setting for this adjustment is +8dBu.
