FCC RF EXPOSURE COMPLIANCE REQUIREMENTS FOR OCCUPATIONAL USE
ONLY
The Federal Communications Commission (FCC), with its action in General Docket 93-62, November 7,
1997, 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 (OSHA) and Federal Communications Commission limits.
DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting more than
50% of the time can cause FCC RF exposure compliance requirements to be exceeded.
This radio is NOT approved for use by the general population in an uncontrolled
environment. This radio is restricted to occupational use, work related operations only
where radio operator must have the knowledge to control the user’s exposure conditions for
satisfying the higher exposure limit allowed for occupational use.
When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm)
away from your mouth.
The radio is transmitting when the red LED on the front of the radio is illuminated. You can
cause the radio to transmit by pressing the PTT bar on the radio.
These are required operating configurations for meeting FCC RF exposure compliance.
Failure to observe these restrictions mean violation.
