requirements.
Compliance with RF Exposure Standards
Your EFJohnson two-way radio is designed and tested to comply with a number of
national and international standards and guidelines (listed below) regarding human
exposure to radio frequency electromagnetic energy. This radio complies with the IEEE
and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty
factors of up to 50% talk and 100% listen and is authorized by the FCC for occupational
use. In terms of measuring RF energy for compliance with the FCC exposure guidelines,
your radio antenna radiates measurable RF energy only while it is transmitting (during
talking), not when it is receiving (listening) or in standby mode.

RF Exposure Compliance and Control Guidelines and Operating
Instructions
Instructions
To control exposure to yourself and others and ensure compliance with the occupational/
controlled environment exposure limits always adhere to the following procedures.
controlled environment exposure limits always adhere to the following procedures.
Guidelines
• User awareness instructions should accompany device when transferred to other users.
• Do not use this device if the operational requirements described herein are not met.
Instructions
Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push
the Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting
50% of the time, or less, is important because this radio generates measurable RF energy
exposure only when transmitting (in terms of measuring for standards compliance).

Transmit only when people outside the vehicle are at least the recommended minimum
lateral distance away, as shown in Table 1, from a properly installed according to
installation instructions, externally-mounted antenna.
