ClearCom FOR-22 - FRONT PANEL CONTROLS AND INDICATORS

FOR-22 4-WIRE INTERFACE
1-2
OPERATION
In normal use, the FOR-22 interface does not require operator interaction. Each
channel features the same set of front panel controls:
• A "send" level control
• A "receive" level control
• A "send level" LED
• A "relay active" LED
"SEND" CONTROLS
The "send" controls affect the level of the signals from the matrix to the external
devices. This control should be adjusted so that the "send level" LED (see below)
lights green when a signal is present. Occasional red flashes due to peaks in the
audio signal are acceptable. The "send" controls have a range of ± 10 dB.
"SEND LEVEL" LEDS
The 2-color "send level" LED lights green when the audio signal is being sent to
the external device at a typical acceptable level. The LED lights red when the
audio output signal level is too high.
"RECV" CONTROLS
The "recv" ("receive") level controls affect the level of the signals sent from the
external devices to the matrix. The "recv" controls have a range of ± 10 dB.
RELAY ACTIVE LED
The amber "relay" LED lights whenever the relay is activated.
