switch to the correct position for the type of batteries that

2.Install the AA batteries. Be sure to observe proper polarity
(+/-). Damage due to improper battery installation may void
the warranty on the product. 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 the batteries. (FIG. A)

3. Plug in the microphone cord (sold separately) using the
“Mic Jack” on top of the transmitter (FIG. B). Do not curl or
wrap the microphone cable. The microphone cable is
also the transmitting antenna.
4. 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 an
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 (FIG. B)
5. Turn the unit on: press and hold the “ON/OFF/MUTE”
button for three seconds. The “Power On” indicator will
illuminate green. (FIG. B)
