Selecting Frequency
The setup screen for frequency selection offers two
ways to browse the available frequencies.
Frequency groups are also able to be received via IR
(Inrared) port sync. The group options are set by the
receiver, and will show at the bottom of the screen as
No Grp, Grp x, Grp w, Grp v, or Grp u.
Use the MENU/SEL button to toggle between options
and UP and DOWN arrows to adjust.

Selecting Programmable Switch Functions
The programmable switch on the top panel can be con-
figured using the menu to provide several functions:
• (none) - disables the switch
• Mute - mutes the audio when switched on; LCD will
blink a message and -10 LED will glow solid red.
• Power - turns the power on and off
• TalkBk - switches the audio output on the receiver
to a different channel for communication with the
production crew. Requires a receiver with this func-
tion enabled.

Selecting the Low Frequency Roll-off
The low frequency audio roll-off is adjustable to op-
timize performance for ambient noise conditions or
personal preference.
Low frequency audio content may be desirable or
distracting, so the point at which the roll-off takes place
can be set to 35, 50, 70, 100, 120 or 150 Hz.

Selecting Audio Polarity (Phase)
Audio polarity can be inverted at the transmitter so the
audio can be mixed with other microphones without
comb filtering. The polarity can also be inverted at the
receiver outputs.

The voltage drop over the life of different batteries var-
ies by type and brand. Be sure to set the correct battery
type for accurate indications and warnings. The menu

If you are using rechargeable batteries, it is better to
use the timer function on the receiver to monitor the
battery life rather than the indicators on the transmitter.
Rechargeable batteries maintain a fairly constant volt-
age across the operating time on each charge and stop
working abruptly, so you will have little or no warning as
they reach the end of operation.
Setting Transmitter Output Power
The output power can be set to 25 mW or 50 mW.
