Transmitter Setup
Battery Selection and Installation
An alkaline 9-volt battery is recommended.
Make certain the
transmitter power switch is Off before installing or changing
batteries.
When inserting the battery,
observe correct polarity as
marked inside the battery compartment.
The transmitter
housings are designed to prevent incorrect installation of the
battery;
do not force the battery in.
Reversed batteries may
cause damage to the transmitter.

Transmitter Battery Installation
1. Slide off the battery cover as shown in Figure E.
2. Carefully insert a fresh 9V alkaline battery, observing polarity
markings.
3. Replace the battery cover (Fig. F).
Handheld Transmitter Battery Installation
1. While holding the upper part of the transmitter body just
below the ball-screen, unscrew the lower body cover and
slide it downward to expose the battery compartment
(Fig. G).
Do not attempt to pull the lower body farther
down, or to gain access to the electronics.
2. Lift the white “battery keeper” arm until it sticks straight out
from the mic body (no higher). Then carefully insert a fresh
9V alkaline battery, observing polarity markings.
3. Screw the body back together.
Do not overtighten.
Battery Condition Indicator
The red battery condition indicator (Fig. I/J) 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. E/G). 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 “Optional System Accessories” on
page 7).
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 transmitter posi-
tions on your body or instrument; or try repositioning the
receiver.
Do not attempt to remove, replace or change the
length of the transmitting antenna.
See pages 8-9 for illustrations.
