5) Once the audio gain has been set, the signal
can be sent through the sound system for
overall level adjustments, monitor settings, etc.
Power ON/OFF Switch Function Selection
The Power On/Off switch can be configured as an audio
mute switch. When used as an audio mute switch,
the power switch causes the transmitter’s audio to be
muted when the switch is placed in the Off position.
The Power LED double blinks green to indicate that the
transmitter is in Audio Mute Mode.
In Audio Mute Mode, the transmitter can still be turned
off by starting with the Power On/Off switch in the On
position, then toggling the Power Switch three times
(ending in the Off position) within five seconds to initiate
the power off sequence. The sequence would be:
On (starting position)-Off-On-Off-On-Off.
Audio Mute Mode will persist when the unit is powered
up again, until it is changed with the procedure at right.
Determine Power Switch Function
Use the following procedure to determine the currently
selected function for the Power On/Off Switch.
1) If the transmitter is turned off, set the Power Switch
On and observe the Power LED to confirm that a
good battery is installed.
2) After the power up sequence completes, place
the POWER On/Off switch in the Off position and
observe the Power LED.
3) If the Power LED slowly double blinks green, the
Power On/Off Switch is in Audio Mute Mode. If the
Power LED fast blinks red then goes out, the Power
Switch is in Normal or Power Mode.
Changing Power Switch Function
1) Ensure the Power On/Off switch is in the On
position.
2) With a battery installed, open the Battery Compart
ment to expose the Frequency Select Switches.
3) With a small screwdriver (included with your unit),
set the Frequency Select Switches to F,F (for
Func
tion,
Function).
4) Rapidly toggle the Power On/Off switch off, then on
again.
5) Set the Frequency Select Switches for the desired
configuration from the choices below:
Normal Mode:
1,1
Audio Mute Mode: 2,2
6) Rapidly toggle the Power On/Off switch off, then on
again.
7) Set the Frequency Select Switches to 0,0.
8) Rapidly toggle the Power On/Off switch off, then on
again.
Note: At this time, the power LED will blink the
code for the selected compatibility mode, just as it
does at powerup, as a comfirmation.
9) To confirm the power switch mode, observe the
behavior of the LED while turning off the transmitter.
Refer to Step 3 in the previous section (Determine
Power Switch Function).
