LT-71: Initial Set-up

Once the LT-71 is charged, follow these steps to set it up for use.

1. Turn the CAT 860 power switch to

the ON position. The RED LED on
the switch will glow.

2. Turn on the LT-71 and set the

operating channel to “B”.

3. Slip the LT-71 with lanyard around

the neck and position the top of
the microphone just below the
collarbone. NOTE: Positioning
of the LT-71 is critical for proper
volume adjustment.

4. While speaking in a normal voice

slowly increase the volume for
Channel B on the CAT 860 until
your voice is barely audible.

REMEMBER: This equipment
supplements the user’s voice
so they are able to speak in a
conversational tone. Having the
volume set too high will result in
feedback and listener fatigue.
