During the following procedures, refer to the above illustration and to the included 
Microphone LED Code Reference Guide (Doc. 7165).

A.  Pair Microphone with Receiver

1.  Hold the MP-FSMIC 

ON

 button until the mic Status LED rapidly flashes green.

2.  The mic will begin pairing with the receiver. Make sure the mic has line of sight to the 

MP-FSIR. When pairing is complete, the Status LED will slowly blink green. Time to 
pair is typically between five and ten seconds.

 

The mic must be turned off and turned on again to pair to another receiver.

B.  Mute and Volume Adjustments

1. Press 

the 

MUTE 

button to mute the mic (observe the blink pattern); press it again to 

un-mute. When muted, the mic automatically turns off after two minutes.

2.  When the mic is not muted, the 

VOL

 button can be used to adjust the mic volume.

3.  When the mic is muted, the 

VOL

 button adjusts the line level audio volume.

4.  Line volume is automatically “ducked” (reduced) when the user talks into the mic.
5. Hold 

the 

MUTE

 button for five seconds to turn off the mic (turns off automatically if 

muted for two minutes, or when placed in the charger.)

6.  If the mic loses sight of the MP-FSIR for seven seconds, the mic will automatically 

mute (turns off automatically if muted for two minutes). 

7.  If the RF link is lost for 10 seconds, the mic turns off.

C. Emergency 

Trigger

Hold the 

ALERT

 button for eight seconds to generate two beeps from the speakers and 

close the alert relay contacts until the button is released.

D.  Receiver Controls - Default Settings

1.

 BASS

 and 

TREBLE

: Typically, set these controls to their center detent positions. 

Slightly reducing treble can help to reduce feedback.

2. 

MASTER VOLUME

: With the control in its center detent position, have the instructor 

speak from the most likely position in the room and adjust this control clockwise so 
that the speakers just begin to exhibit feedback, and then reduce the setting by 
turning counterclockwise.
