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

Minimum Lateral Distance from

Mobile Two-Way Radio

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.
