• 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.

1-3.2 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.
• As with all fixed site antenna installations, it is the responsibility of the licensee to manage the site
in accordance with applicable regulatory requirements and may require additional compliance
actions such as site survey measurements, signage, and site access restrictions in order to ensure
that exposure limits are not exceeded.

1-3.3 Electromagnetic Interference/Compatibility

Note Nearly every electronic device is susceptible to electromagnetic interference (EMI)
if inadequately shielded, designed, or otherwise configured for electromagnetic
compatibility. It may be necessary to conduct compatibility testing to determine if
any electronic equipment used in or around vehicles or near fixed site antenna is
sensitive to external RF energy or if any procedures need to be followed to
eliminate or mitigate the potential for interaction between the radio transmitter
and the equipment or device.
