Transmitter Power/Mute/Battery Indicator
After the battery is installed, press and hold the power button until the
indicator LED turns green
(Fig. E). If the indicator LED does not light up
when the power button is pressed, the batteries are installed incorrectly
or they are dead. The indicator LED will flash to show low-battery
condition.

Transmitter Input Connection
Connect an audio input device (microphone or guitar cable) to the
audio input connector on the top of the transmitter. A number of
Audio-Technica professional microphones and cables are available

®

Transmitter Antenna
The UniPak
®
transmitter includes a permanently-attached flexible
antenna. For best results, allow the antenna to hang freely and
full length from the transmitter. If the received signal is marginal,
experiment with different transmitter positions on your body or
instrument; or try repositioning the receiver. Do not attempt to
remove, replace or change the length of the transmitting antenna.
