Compliance and Control Guidelines and Operating Instructions
for Mobile Two-Way Radios Installed in Vehicles
To control your exposure and ensure compliance with the occupational/ controlled
environment exposure limits, always adhere to the following procedures:
• To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the
PTT button. Transmit only when people outside the vehicle are at least the
minimum lateral distance away (as shown in table below) from a properly
installed, externally-mounted antenna.
The table below lists the minimum lateral distance for bystanders in an
uncontrolled environment from the transmitting antenna at several different ranges
of rated radio power for mobile radios installed in a vehicle.
Rated Power of Vehicle-Installed
Mobile Two-Way Radio
Minimum Lateral Distance from
Transmitting Antenna
Less than 7 watts 8 inches (20 centimeters)
7 to 15 watts 1 foot (30 centimeters)
16 to 50 watts 2 feet (60 centimeters)
51 to 110 watts 3 feet (90 centimeters)
• Install mobile antennas at the center of the roof or the center of the trunk deck
per specific guidelines and instructions in the Radio Installation Manual. These
mobile antenna installation guidelines are limited to metal body vehicles.
Use only the Motorola-approved, supplied antenna or a Motorola- approved
replacement antenna. Use of non-Motorola-approved antennas, modifications, or
attachments could damage the radio and may violate FCC regulations.

Compliance and Control Guidelines and Operating Instructions for
Mobile Two-Way Radios Installed as Fixed Site Control Stations
If mobile radio equipment is installed at a fixed location and operated as a control station
or as a fixed unit, the antenna installation must comply with the following requirements in
order to ensure optimal performance and compliance with the RF energy exposure limits
in the standards and guidelines listed in the Federal Communication Commission
Regulations section.
• The antenna should be mounted outside the building on the roof or a tower if at all
possible.
