Mic Muffs

The headset microphone is covered with a washable, replaceable foam mic muff. This mic

muff helps prevent the “pops” and “hisses” that can occur from speaking into a microphone

that is close to the mouth.

To clean or replace the mic muff:

1. Remove the o-ring.

2. Slip the mic muff off the microphone.

3. At this time, you can decide whether

to clean or replace the mic muff.

If you clean the mic muff, use a mild detergent, rinse it out well and let it

dry completely before re-installing it on the microphone.

4. Slide the mic muff on the microphone.

5. Install the o-ring on the mic muff to secure it.

Replacement mic muffs may be ordered from Firecom

Intercom Communication

The UHW-20 headset has a black momentary PTT button located on the bottom side of the

right ear dome. Press and hold this button to activate the microphone for intercom communi-

cation. Radio transmitting is not possible with the UHW-20 model.

The UHW-10 and the FHW-10 models have a red momentary PTT button located on the

bottom of the right ear dome. The microphone on these two models is always live for internal

intercom communications. However, press and hold the red button to transmit over the radio.

Release the button to terminate radio transmission.

Pairing

When one or more wireless headsets is purchased with a base station, the headset will be

prepaired to the base station at the factory so the pairing procedure listed below will not be

necessary.

Pairing Procedure

1. Press and hold the pairing button on the front panel of the base station until the yellow

LED(s) on the front panel of the base station start flashing, indicating that the base station

has entered pairing mode. Once the base station is placed in pairing mode, the user has

approximately 15 seconds to place the headset in pairing mode.

2. Press and hold the PTT button, turn on power to the headset. After approximately 5 seconds,

the green and red LEDs on the outside of the left ear dome will start flashing in a relatively

fast alternating pattern. Release the PTT button.

3. Monitor the green and red LEDs on the left ear dome of the headset. After about 5-7

seconds, the alternating flashing pattern ends, the green LED will flash rapidly for two seconds

then the green and red LEDs resume normal operation (as stated in the section titled “LED

Indicators”) to indicate that the headset is paired and connected to the base station. The

respective LINK LED on the base station will illuminate steadily after flashing rapidly for two

seconds to indicate that connection to the headset has been established.
