8-Channel 900 MHz Wireless Microphone
Your RadioShack 8-Channel 900 MHz Wireless Microphone is de-
signed for use as a public address microphone or for professional
music performances, and is perfect for use with the RadioShack
8-Channel 900 MHz Wireless Receiver (Cat. No. 32-1250).
FCC STATEMENT
Your equipment might cause TV or radio interference even when it is
operating properly. To eliminate interference, you can try one or
more of the following corrective measures:
• reorient or relocate the receiving antenna
• increase the distance between the equipment and the radio or
TV
If you cannot eliminate the interference, the FCC requires that you
stop using your microphone.
This device complies with Part 15 of the
FCC Rules
. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interfer-
ence received, including interference that may cause undesired op-
eration.
Warning: Changes or modifications to this unit not expressly ap-
proved by the party responsible for compliance could void the user’s
authority to operate the equipment.
Shielded cables must be used with the unit to ensure compliance
with the Class FCC limit.
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 recom-
mended 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 bat-
tery compartment is accessible (see “Setting the Channel”).
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 op-
erating 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
the 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.

USING THE MICROPHONE
1. Follow the directions in the receiver’s owner’s manual to set up
and power on the receiver.
2. Turn on your amplifier, tape recorder, mixing board, and other
necessary components of you audio system. Set the compo-
nents’ volume control (or input level controls) to moderate set-
tings.
3. Set the receiver and microphone’s channels to the same set-
tings (see “Setting the Channel”).
4. Slide STANDBY ON/OFF on the microphone to ON. (When power
is on and the battery is good, LOW BATT lights.)
5. Set TALK/MUTE to TALK. Begin to talk into the microphone and
adjust the receiver’s volume control as desired.
Note: Experiment with the receiver’s volume and the settings of
other components in your audio system to obtain the best
results.
6. When you finish, slide STANDBY ON/OFF to OFF.
USING MUTE
Slide TALK/MUTE to MUTE to temporarily turn off the microphone’s
sound without turning off its power.
If you turn off the microphone (slide STANDBY ON/OFF from ON to
OFF) while the amplifier is on, the speakers emit a loud pop. When
you use MUTE, there is no pop.
CARE
Keep the microphone dry; if it gets wet, wipe it dry immediately. Use
and store the microphone only in normal temperature environments.
Handle the microphone carefully; do not drop it. Keep the micro-
phone away from dust and dirt, and wipe it with a damp cloth occa-
sionally to keep it looking new.
Modifying or tampering with the microphone’s internal components
can cause a malfunction and might invalidate its warranty and void
your FCC authorization to operate it. If your microphone is not per-
forming as it should, take it to your local RadioShack store for assis-
tance.
