Install batteries

Unscrew the microphone grille and remove

the battery cover. Insert two AA batteries with

correct polarities. Then replace the battery

cover and the microphone grille.

Battery Notes:

• Dispose of old batteries promptly

and properly. Do not burn or bury

batteries.

• Use only fresh batteries of the required

size and recommended type. Do not

indicating that the microphone signals are within range of

the receiver.

Notes:

• To avoid a popping noise that may occur when switching

from OFF to TALK, use MUTE.

• When you finish using the system, turn TALK-MUTE-OFF to

OFF.

•

The frequency version of your system is preset. When

two sets at same operating frequency work close to each

other, they have mutual interference. In order to minimize

interference, three different operating frequencies are

provided. When using wireless microphones simultaneously,

make sure your system’s frequency versions are different.

Check the frequency label on the bottom of the receiver

and inside the microphone’s battery compartment.

FCC Information

WARNING: Modifying, tampering with, or adjusting this unit, or replacing any

transmitter component (crystal, semiconductor, etc.) may result in a violation of the

FCC rules.
NOTE: This equipment has been tested and found to comply with the limits

for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits

are designed to provide reasonable protection against harmful interference in

a residential installation. This equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in accordance with the instructions,

may cause harmful interference to radio communications. However, there is no

guarantee that interference will not occur in a particular installation. If this equip-

ment does cause harmful interference to radio or television reception, which can be

determined by turning the equipment off and on, the user is encouraged to try to

correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

• Consult your local RadioShack store or an experienced radio/TV technician for

help.

If you cannot eliminate the interference, the FCC requires that you stop using

your microphone system. Changes or modifications not expressly approved by

RadioShack may cause interference and void the user’s authority to operate the

equipment.
Shielded cables must be used with this unit to ensure compliance with the Class B

FCC limits.
This device complies with Part 15 of the FCC Rules. Operation is subject to the

condition that this device may not cause harmful interference.
This wireless microphone system complies with Part 90 of the FCC Rules. There

are three frequencies available for the system. You must obtain a license for each

frequency you plan to use before operating your system. One license can include

both frequencies. Visit http://wireless.fcc.gov/uls/, or call your local FCC office to

apply for your license. Your ability to obtain a license will depend on how you plan

to use the system.
For RF exposure
IMPORTANT NOTE: To comply with the FCC RF exposure compliance require-

To comply with the FCC RF exposure compliance require-

ments, no change to the antenna or the device is permitted. Any change to the

antenna or the device could result in the system exceeding the RF exposure

requirements.
For devices less than 200mW ERP
SAFETY INFORMATION
Your wireless microphone contains a low power transmitter. When the EUT is

powered on, it sends out radio frequency (RF) signals. In August 1996, the Federal

Communications Commissions (FCC) adopted RF exposure guidelines with safety

levels for wireless devices.
IMPORTANT
To maintain compliance with the FCC’s RF exposure guidelines, hold the transmitter

and antenna at least 1 inch (2.5 centimetres) from your face and speak in a normal

voice, with the antenna pointed up and away from the face. Ensure that the antenna

is at least 1 inch (2.5 centimetres) from your body when you are using your wireless

microphone.
Use only the supplied antenna. Unauthorized antennas, modifications, or attach-

ments could damage the transmitter and may violate FCC regulations.
