SETTING THE CHANNEL AND INSTALLING THE BATTERY

Your transmitter can transmit on three different channels so you can use
more than one system at the same time without interference.  If you intend
to operate more than one system, you must set a different channel for each
transmitter and receiver system.  Each channel frequency is identified by
a different letter.  If your transmitter is set to channel B, your receiver
must also be set to channel B.  Do not operate two systems in the same
location on the same channel or on adjacent channels.

NOTE:  If you are using only one system, you do not have to change the
       transmitter channel, Instead, set the receiver channel to match the
       transmitter channel.

To set the transmitter channel, do the following.

1.  While holding the body of the microphone, carefully unscrew and remove
    the tapered lower section of the microphone.

    CAUTION:  Static electricity can damage your microphone.  To avoid
              possible damage, you should discharge any static electricity
              from your body by touching a faucet or other grounded metal
              object before you set the transmitter channel.

2.  Set the transmitter switch to the desired channel.  Do not handle the
    printed circuit board or remove the protective shield.

    NOTE:  System microphones are sold in three channel combinations:

           AEH, BDG, or CFH

3.  Replace the lower section of the microphone body.

INSTALLING THE TRANSMITTER'S BATTERY

The microphone's transmitter is powered by a single 9-volt battery.  For 
the longest battery life, we recommend an alkaline battery (Radio Shack
Cat. No. 23-553).

1.  While holding the body of the microphone, carefully unscrew the ball
    grill assembly far enough to remove the battery door.

2.  Insert the battery into the battery compartment on top of the ribbon,
    being sure the + and - terminals are connected correctly as shown on
    the inside of the battery compartment.

3.  Replace the battery compartment cover and tighten the ball grill
    assembly.
