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.
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.
