On/Off Switch Function Selection
The On/Off switch can be configured to control power or
to function as an audio mute switch. When it is con-
figured as an audio mute, the transmitter power can
still be turned off by starting with the switch in the On
position, then toggling it three times within five seconds
(ending in the Off position).
The Audio Mute mode will persist between power
cycles until it is changed with the following procedure.
The Power LED slowly double blinks green to indicate
that the transmitter is in Audio Mute Mode.
Changing Power Switch Function
1) Remove the battery cover and install a battery.
Leave the battery cover off the unit for access to the
internal switches, and close the ring so the battery
will make contact.
2) Turn the switch on and verify the battery is good.
The LED should glow green continuously.
3) Use the small screwdriver to set the Frequency
Switches to F,F (Function, Function).

Determining 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
the Switch is in Audio Mute Mode and the power
is still turned on. If the LED blinks red briefly, then
goes out, the switch is in Normal mode (turns the
power on and off).
