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. E).
2. 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. D/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.
Body-Pack Transmitter Input Connection
Connect an audio input device (included lavalier microphone, guitar cable or headworn
microphone) to the input connector on the top of the transmitter. This is a screw-down locking
connector. To lock the connector to the transmitter, screw the silver locking ring on the threaded
portion of the input connector clockwise. To remove the connector, unscrew the silver locking
ring counterclockwise, and then simply pull up on the connector's metal collar.
Transmitting Antenna
The body-pack transmitter uses the attached mic/guitar cable as the antenna. Due to
this feature, any modification of the cable length or connector termination will affect the
performance. If the received signal is marginal, experiment with different transmitter positions
on your body or instrument or try repositioning the receiver.
