1.12.3 EXPOSURE COMPLIANCE AND CONTROL GUIDELINES AND
OPERATING INSTRUCTIONS
To control exposure to yourself and others and ensure compliance with the
occupational/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.
NOTE
: Table 1-2 lists the recommended minimum lateral distance for bystanders in an
uncontrolled environment from transmitting types of antennas (i.e., monopoles over a ground
plane, or dipoles) at several different ranges of rated radio power for mobile radios installed in a
vehicle.

1.12.4 MOBILE ANTENNAS
•
Install antennas at the center of the roof or the center of the trunk deck taking into account the
bystander exposure conditions of backseat passengers and the recommended minimum lateral
distances in Table 1-2. These mobile antenna installation guidelines are limited to metal body
motor vehicles or vehicles with appropriate ground planes. The antenna installation should
additionally be in accordance with:
a.) The requirements of the antenna manufacturer/supplier.
b.) Instructions in the Radio Installation Manual, including minimum antenna cable lengths.
