Transmitter Battery Condition Indicator
The red battery condition indicator (Fig. E) should light strongly with a
fresh battery. As the battery weakens, the indicator will grow dimmer.
When the indicator becomes very dim or goes out, there is little life
left in the battery. Replace it at once for continued operation of the
transmitter.
All transmitters feature battery-save switches (Fig. D). As supplied, the
switch is set in the High position for maximum range. Switching to the
Low position increases battery life by reducing power. (Note: Effective
range decreases when the switch is set in Low position.)

Transmitter Input Connection
Connect an audio input device (microphone or guitar cable) to the
input connector on the bottom of the transmitter. The cable connector
latches automatically when inserted into the transmitter jack. To
unlatch and remove the connector, simply pull up on the connector’s
knurled metal collar.
A number of Audio-Technica professional microphones and cables are
available separately, pre-terminated with a UniPak
®
input connector
(see www.audio-technica.com).

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 bottom of 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.
