the mics and receivers that have the features that best fit  
your needs.  
This device complies with Part 90 of the FCC Rules. There  
are a total of eight frequencies available for this  
microphone. Each microphone has channels that can  
operate on three of these frequencies. You must get a  
license for each frequency you plan to use before you use  
the microphone. Licensing eligibility depends on how you  
will use the microphone. Contact your nearest FCC office to  
get the necessary application.  
INSTALLING THE BATTERY  
The microphone’s transmitter is powered by a single 9-volt  
battery. For the longest battery life, we recommend an  
alkaline battery.  
Caution: Use only fresh batteries of the required size and  
recommended type.  
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.  
Low Battery Indications  
The microphone’s BATT LOW indicator tells you the  
condition of the battery.  
If the indicator flickers when you move the microphone’s  
switch from OFF to STBY, the battery is good.  
If the indicator lights when you are using the microphone (in  
the ON or STBY position), battery power is low and you  
should 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  
several weeks, remove the battery. Batteries can leak  
chemicals that can destroy electronic parts.  
SETTING THE CHANNEL  
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  
3
 
 
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.  
Notes:  
• System microphones are sold in three channel  
combinations:  
A E H, B D G, or C F H  
• 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.  
Using More Than One Wireless System  
If you intend to use more than two wireless microphone  
systems in the same location, follow the recommended  
channel combinations listed for best performance.  
Combinations  
1: C E H  
Combinations  
5: B D H  
2: A C F  
6: C F H  
3: A D F  
7: B E G  
4: B D G  
8: B E H  
Important: Always use the STBY setting on your  
transmitter to mute a microphone. Using the STBY setting

minimizes interference when you use more than one  
wireless system.  
To set the transmitter channel, do the following.  
Battery  
Compartment  
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.  
3. Replace the lower section of the microphone body.  
OPERATION  
1. Fully extend the receiver’s antenna.  
2. Turn on your amplifier, tape recorder, mixing board,  
and other necessary components of your audio  
system. Set the volume control (or input level controls)  
to moderate settings.  
3. Set the receiver’s volume control to its minimum  
setting.  
4. Press the receiver’s power button to the on position.  
The green power indicator lights.  
5. Set the receiver channel switch to the same channel  
as the transmitter.  
6. Set the microphone’s ON/STBY/OFF switch to ON. The  
receiver’s red READY indicator lights.  
7. Begin talking into the microphone and adjust the  
receiver’s volume control to the desired level.

Note: Experiment with the receiver’s volume setting and  
the settings of other components in your audio system to  
obtain the best results.  
Using the Standby Setting  
The microphone’s STBY setting lets you turn off the  
microphone without turning off the microphone’s  
transmitter.  
If you move the switch from ON or STBY to OFF while your  
amplifier is on, there is a loud pop. There is no pop when  
you move the switch from STBY to ON, or from ON to STBY.  
To conserve battery power, be sure to set the switch to OFF  
when you finish using the microphone.
