user’s guide
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.
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 equipment 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.
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 requirements,
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 attachments
could damage the transmitter and may violate FCC regulations.
limited one-year warranty
This product is warranted by RadioShack against manufacturing defects in material and
workmanship under normal use for one (1) year from the date of purchase from RadioShack
company-owned stores and authorized RadioShack franchisees and dealers. For complete
warranty details and exclusions, check with your local RadioShack store.
