7. MUTING FUNCTION

7.1. Manual Mute

Step 1. Set the inputs to be muted (Mute Receive inputs) with the Function switch B.

Shift the DIP switches 1 to 5 to ON position to place each corresponding input in Mute Receive

(muted) mode as follows.

• DIP switch 1: MIC input

• DIP switch 2: LINE 1/TEL input

• DIP switch 3: LINE 2 input

• DIP switch 4: LINE 3 input

• DIP switch 5: MODULE input

Note

Avoid assigning both Mute Receive and Mute Send functions to the same input.

Step 2. Close between the Manual mute (+) and (–) terminals.

The Inputs set for Mute Receive in Step 1 are muted.

Step 3. Open between these terminals.

The signal being muted returns gradually to its original level in about 1 to 5 seconds.

Note: This function is active regardless of the Automatic mute ON/OFF setting using the Function switch A.

Manual mute and Automatic mute are available for the muting function.

Manual mute is a function to mute the MIC, LINE 1/TEL, LINE 2, LINE 3 and/or MODULE input placed in Mute

Receive mode when the manual mute terminal is short-circuited.

Automatic mute is an audio-signal activated muting function to automatically mute the MIC, LINE 1/TEL, LINE

2, LINE 3 and/or MODULE input placed in Mute Receive mode when audio signals enter the MIC, LINE

1/TEL, or MODULE input placed in Mute Send mode.

Neither manual mute nor Automatic mute works on the MOH output.
