Diagram
Carefully insert a fresh 9-volt alkaline battery, observing correct polarity as marked inside the
battery compartment. The transmitter housing is designed to prevent incorrect installation of the
battery. Do not force the battery in.
Replace the battery cover (Fig. C).

Move the power switch to "On" and make certain the red battery condition indicator is strongly
illuminated.
Return the power switch to the "Off" position.
Handheld Transmitter Battery Installation
Make certain the power switch on the bottom of transmitter is in the "Off" position.
While holding the upper part of the transmitter body just below the ball-screen, unscrew the
lower body and slide it downward to expose the battery compartment (Fig. D). Do not attempt
to pull the lower body farther down, or to gain access to the electronics.

Battery-Save
Switch
Lift the white "battery keeper" arm until it sticks straight out from the mic body (no higher). Then
carefully insert a fresh 9-volt alkaline battery, observing correct polarity as marked inside the battery
compartment. The transmitter housing is designed to prevent incorrect installation of the battery.
Do not force the battery in.
Move the white arm down until it presses on the battery, then slide the lower body portion back
up until it covers the battery and engages the threads of the upper body. Screw the body back
together; do not overtighten.
Move the power switch on the bottom of transmitter to "On" and make certain the red battery
condition indicator is strongly illuminated.
Return the power switch to the "Off" position.
Battery Condition Indicator
The red battery condition indicator (Fig. E/F) 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. B/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 the Low position.)

Transmitter Input Connection
Connect an audio input device (microphone or guitar cable) to the input connector on the bottom
of the transmitter.
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 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.
