RF power may be set to "RF HI" (30 mW nominal) or "RF LOW" (10 mW nominal) through the
function menu. The default setting is "RF LOW". While the High setting normally provides
maximum operating range, the Low setting will help extend battery life. The Low setting may also
be preferred in multichannel systems, or when operating very close to the receiver, to reduce the
possibility of interference or receiver RF overload.
Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input and
on your Transmitter
output levels is important for best performance.
A 4-position audio input gain setting, selected through the function menu, allows you to match the
audio input level to the transmitter for best modulation with minimum distortion. The choices are
+12 dB, +6 dB, 0 dB and -6 dB. The default value is +6 dB. Select the highest setting that does not
result in over-modulation with the highest audio/instrument input levels (an AF
indication on the receiver no higher than "0").
When the transmitter is muted, it produces RF with no audio. When the transmitter is
on your Transmitter
un-muted, it produces both RF and audio. To mute the transmitter (cut off the audio, but
continue the RF output), press and release the Power/Mute button once. The word "MUTE" will
appear in the LCD window, just below the frequency, and the Power-on LED will turn red.
To un-mute the transmitter (restore the audio), press and release the Power/Mute button once
again. The "MUTE" will disappear from the LCD window, and the Power-on LED will turn green.
Power/Mute Locks
The Power/Mute button can be programmed (through the function menu): power can be locked On;
Mute can be locked either On or Off.

In "MUT.LOC" mode, the audio cannot be muted. The Power functioning is
unaffected. (If "MUT.LOC" is applied while the transmitter is muted, pressing the
Power/Mute button once will return to un-muted operation; thereafter the Mute
function is disabled until the setting is changed again.)
Power is locked On as of the time "PWR.LOC"is applied. The Mute functioning
is unaffected. Note: When in the "PWR.LOC" mode, the transmitter may be
turned off by: (1) Re-accessing the .LOC Menu and changing the setting, or
(2) Removing and re-installing the batteries. When the transmitter is
turned on again, it will power-up in the "NO.LOC" mode.
