Operating Instructions
IMPORTANT: If Alkaline (non-rechargeable) batteries are being installed, slide the
battery selection switch in the battery compartment to the “Alkaline” position.
See FIG. A below. If installing NiMH (or rechargeable) batteries, slide the battery
selection switch to the “NiMH” position.
1. Install AA batteries: Open the battery compartment by pressing and lifting
the tab on the back of the transmitter with your finger. To remove depleted
batteries, pull up on the fabric strip.
Press the batteries into place over the fabric strip. Be sure to observe proper
polarity (+/-). Damage due to improper battery installation may void the warranty
on the product. Close the battery door. The “Power On” LED on top of the unit will
flash when the batteries are getting low; you may continue to use until the unit quits
operating, then replace or recharge batteries.

2. Plug the microphone cord (sold separately) into the “Mic Jack” on top of the
transmitter (FIG. B).
3. Optionally, plug in a desired audio source such as a CD or MP3 player using the
“Auxiliary Input” jack (WCA 087 stereo auxiliary input cable included). If mic and
auxiliary sources are used together, the audio will be mixed. If only auxiliary source
is desired, the mic can be muted. Do not remove the mic from the “Mic Jack” as
the cable is also the transmitting antenna!
4. Turn the unit on: press and hold the “ON/OFF/MUTE” button for three seconds. The
“Power On” indicator should illuminate green.
5. Select the desired operating frequency. Use the “Channel Selector” knob to select
any of the 16 available channels on 72-76 MHz. Refer to the channel selection
chart, FIG C.
