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.
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 (Fig. G).
3. Replace the lower body cover.
Do not overtighten.
Battery Condition Indicator
When the transmitter is turned on with a fresh battery installed,
the red LED battery condition indicator (Fig. I/J) will flash
strongly once, then reduce to a continuous dim glow. As the
battery weakens, the LED's glow will increase. When the LED's
glow becomes substantially brighter, there is little life left in the
battery. (When the battery is mostly exhausted, the LED will
cease to light.) As soon as the LED noticeably brightens,
replace the battery promplty for continued operation of the
transmitter.

Transmitter Input Connection
Connect an audio input device (microphone or guitar cable) to
the 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 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.
Mounting Clip
The mounting clip on the UniPak transmitter may be attached
so it is positioned either “up” or “down” in relation to the case,
depending upon which is preferred for the application. To
change the clip direction, simply (1) spread the ends of the clip
until it comes free of the holes in the sides of the case; (2)
position the clip with the desired orientation; (3) spread the clip
slightly again so it clears the sides of the case; and (4) make
certain the clip ends are fully seated in the mounting holes in
the case. Best performance usually results when the antenna is
hanging freely at full length.
