Safety Information
The Federal Communications Commission (FCC), with its action in
General Docket 79-144, March 13, 1985, has adopted a safety
standard for human exposure to Radio Frequency (RF) electromagnetic
energy emitted by FCC regulated equipment. Maxon subscribes to the
same safety standard for the use of its products. Proper operation of this
radio will result in user exposure far below the Occupational Safety
and Health Act and Federal Communications Commission limits.
WARNING - DO NOT hold the radio in such a manner that the
antenna is next to, or touching, exposed parts of the
body, especially the face or eyes, while transmitting.
WARNING -DO NOT allow children to operate transmitter - equipped
radio equipment.
CAUTION - DO NOT operate the radio near unshielded electrical
blasting caps or in an explosive atmosphere unless it
is a type especially designed and qualified for such use.
CAUTION - DO NOT press and hold the transmit switch (P-T-T) when
not actually wishing to transmit.
NOTE: This radio operates in FCC regulated frequency
bands. All radios must be licensed by the FCC before
use. Because this radio contains a transmitter, Federal
law prohibits unauthorized use or adjustments of this
radio.
