8-Channel 900 MHz Wireless Microphone
(320-1251)                 Preparation                Faxback Doc. # 63539

Installing the Battery

Your microphone 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.  Hold the microphone in one hand and gently unscrew the ball grille
    with the other hand.

2.  Grasp the battery compartment cover and lift it off.

3.  Set CHANNEL SELECTOR to the desired channel while the battery
    compartment is accessible (see "Setting the Channel" below).

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

5.  Insert the compartment cover's tabs into the recesses first, then set
    the cover back into place.

6.  Gently screw the ball grille back onto the microphone.

When power is on, LOW BATT lights.  When the sound becomes weak or 
distorted, LOW BATT flashes, or the microphone 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 microphone for a week or longer,
         remove the battery. Batteries can leak chemicals that can destroy
         electronic parts.

Setting the Channel

Your wireless microphone has eight channels. Follow these steps to set the 
channel.

1.  Slide STANDBY ON/OFF to OFF.

    Notes: Both the microphone and the receiver:

             Should be powered off before setting or changing the channel.

             Should be set to the same channel.

2.  Hold the microphone in one hand and gently unscrew the ball grille
    with the other hand.

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

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