Installing the Battery

Your transmitter requires one 9V battery (not supplied) for power.  For
the best performance and longest life, we recommend using a RadioShack
alkaline battery.

CAUTION: Use only a fresh battery of the required size and recommended
         type.

1.  Slide the transmitter's battery compartment cover in the direction of
    the arrow to remove it.

2.  Snap the battery in the compartment as indicated by the polarity
    symbols (+ and -) marked inside.

3.  Replace the battery compartment cover.

When power is on, POWER/LOW BATT lights.  When POWER/LOW BATT flashes or
the transmitter stops operating properly, replace the battery.

WARNING: Dispose of old batteries promptly and properly.  Do not burn or
         bury them.

CAUTION: If you do not plan to use the transmitter for a week or longer,
         remove the batteries.  Batteries can leak chemicals that can
         destroy electronic parts.

Using the Belt Clip

For hands-free carrying, attach the supplied belt clip. Align the dovetail
tracks in the grooves on the back of the transmitter, then slide the clip
down until it clicks to secure it.  To attach the transmitter, slide the
clip over your belt.  To remove the belt clip from the transmitter, lift
the center tab on the clip and slide the clip up.

Setting the Channel

Note: Both the transmitter and any receiver you use:

        Should be powered off before setting or changing the channel.

        Should be set to the same channel.

1.  Remove the battery compartment cover.

2.  Use a pointed object (such as a straightened paper clip) to set
    CHANNEL SELECTOR (dip switches) according to the chart below for the
    desired channel.

Connecting an Audio Source

Note: If your audio source's cable does not have the appropriate connector
      to attach to the transmitter, use an adapter available at your local
      RadioShack store.

You can connect a LINE level source (such as an electronic keyboard,
musical instrument microphone, or electric guitar) or a MIC level source
(such as a headset microphone) to the transmitter.

To a LINE Level Source

To connect a line-level source to the transmitter, use a cable with a 1/4
inch (6.35 mm) phono plug.

1.  Plug one end of the cable into the transmitter's LINE jack.

2.  Plug the other end into the audio source's output jack.

3.  Follow the instructions in the owner's manuals for your other audio
    equipment to make all other connections.

To a MIC Level Source

To connect a MIC level source to the transmitter, use a cable that ends in
a 1/8 inch (3.5 mm) phono plug.

1.  Plug one end of the cable into the transmitter's MIC jack.

2.  Plug the other end into the audio source's output jack.

3.  Follow the instructions in the owner's manuals for your other audio
    equipment to make all other connections.

Setting the Transmitter's Input Sensitivity Level

Your transmitter is designed to operate with musical instruments,
microphones, and other audio devices.  To get the best performance from
the system, set the transmitter input sensitivity to match the source.

The factory setting should be suitable for most uses.  If you experience
very low volume or distorted sound, follow these steps to adjust the
sensitivity.

1.  Remove the battery compartment cover.

2.  Rotate VOLUME to adjust sensitivity.

      To set the receiver's volume control to a higher setting in order to
      hear the audio source better, turn VOLUME to the left about 1/8-1/4
      turn, then test the system again.

      To set the receiver's volume control to a lower setting in order to
      hear more clear audio, turn VOLUME to the right about 1/8-1/4 turn,
      then test the system again.

3.  Replace the cover.
