Mobile Antenna Installation Guidelines - Motorola MTM800 User Manual

PRODUCT SAFETY and RF Energy Exposure
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 that 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 the body of a vehicle with a properly
installed antenna. This separation distance will ensure that there is sufficient distance from a
properly installed (according to installation instructions) externally-mounted antenna to satisfy
the RF exposure requirements in the standards listed above.
Note: Table 1 lists the recommended lateral distance for bystanders in an uncontrolled
environment from the body of a vehicle with an approved, properly installed transmitting antenna
(i.e. monopoles over a ground plane, or dipoles) at several different ranges of rated radio power
for mobile radios installed in a vehicle.
Note: If you are not sure of the rated power of your radio, contact your Motorola representative or
dealer and supply the radio model number found on the radio model label. If you cannot determine
the rated power out, then assure 90cms (3 feet) separation from the body of the vehicle.

Mobile Antenna Installation Guidelines

• These mobile antenna installation guidelines are limited to metal body motor vehicles or vehicles
with appropriate ground planes.
• Antennas should be installed in the centre area of the roof or the trunk lid taking into account the
bystander exposure conditions of backseat passengers and according to the specific instructions
and restrictions in the Radio. Installation Manual along with the requirements of the antenna
supplier.
• Trunk lid installations are limited to vehicles with clearly defined flat trunk lids, and in some
cases, to specific radio models and antennas. See the Radio Installation Manual for specific
information on how and where to install specific types of approved antennas to facilitate
recommended operating distances to all potentially exposed persons.
