Operating the LT-700 Transmitter
Make sure the unit is on.
When you press the power button, the LED on top of
the unit will be illuminated.
Select the channel for transmitting.
Please refer to “Selecting a Channel for Transmitting”
on Page 10 for guidelines on choosing an interfer-
ence-free channel.
To select a channel, press either the channel UP or
DOWN button until the display reads the channel you
want. To lock your selection, press and hold the UP
or DOWN button for 3+ seconds. When locked, the
small padlock will be visible on the display. Press and
hold the button again to unlock.
At 72MHz:
The LT-700 operates on 17 wide band channels and
40 narrow band channels. Channels represented by
letters in the display (i.e. A) are wide band channels;
channels represented by numbers are narrow band
channels.
At 216MHz:
The LT-700 operates on 19 wide band channels and
38 narrow band channels. Channels beginning with a
“2” are wide band channels and channels beginning
with a “1” or “3” are narrow band channels.
Listen recommends using wide band channels
whenever possible, as they are not as noisy as
narrow band channels.
Refer to the Frequency Compatibility tables (pages
39-42) for specific frequencies and compatibility with
other manufacturers. Also refer to Appendix A,
“Which Channel(s) Should I Use?” on page 43.

Close the Access Door.
Lock it if desired by turning the locks on the side of
the unit to the vertical position.
Make sure the red MUTE / TALK switch on
top of the unit is in the correct position.
This switch is a handy way to “turn off” the
microphone when needed; just slide it to the MUTE
position. Return it to the TALK position to resume
your audio. When MUTE is active, the microphone is
muted and the LED on top of the unit will flash
rapidly. If you are using line level audio, it will not be
muted.
