Transmitter Setup
Battery Condition Indicator
The red battery condition indicator (Fig. H/I) 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.
Battery-Save Switch
All transmitters feature battery-save switches (Fig. D/F). As
supplied, the switch is set in the "H" (high) position for maxi-
mum range. Switching to the "L" (low) position increases battery
life by reducing power. (Note: Effective range decreases when
the switch is set at the "L" position.)

Connector
UniPak Transmitter Input Connection
Connect an audio input device (microphone or guitar cable)
to the audio input connector on the bottom of the transmitter.
A number of Audio-Technica professional microphones and
cables are available separately, pre-terminated with a UniPak
input connector (see "Optional System Accessories" on
page 6.)
Transmitting 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 transmit-
ter 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.
