							FCC RF EXPOSURE INFORMATION
WARNING!Read this information before using the radio 
In August 1996 the Federal Communications Commission (FCC) of the
United States with its action in Report and Order FCC 96-326 adopted
an updated safety standard for human exposure to radio frequency
electromagnetic energy emitted by FCC regulated transmitters.
Those guidelines are consistent with the safety standard previously set
by both U.S. and international standards bodies. The design of the radio
complies with the FCC guidelines and these international standards.
• Never allow children to operate the radio without adult
supervision and the knowledge of the following guidelines.
WARNING!It is up to the user to properly operate this radio
transmitter to insure safe operation. Please adhere 
to the following:
Use only the supplied or an approved antenna. Unauthorized antennas,
modifications, or attachments could impair call quality, damage the
radio, or result in violation of FCC regulations.
Do not use the radio with a damaged antenna. If a damaged antenna
comes into contact with the skin, a minor burn may result. Please
contact your local dealer for a replacement antenna.
Body-worn Operation
This device was tested for typical body-worn operations using the
supplied belt-clip. To maintain compliance with FCC RF exposure
requirements, body-worn operations are restricted to the supplied 
belt-clip.
For hand-held operation, the radio should be held 1 inch from the users
face. The use of accessories that do not satisfy these requirements may
not comply with FCC RF exposure requirements and should be
avoided. For more information about RF exposure, please visit the FCC
website at www.fcc.gov.
• When using an external speaker microphone, USE ONLY THE
UNIDEN MODEL HHVTA07 (black) or HHVTAW07 (white). Use
of any other accessory for this purpose may invalidate your
authority to operate this device.
