1. SAFETY
1.1 MAXIMUM PERMISSIBLE EXPOSURE
(MPE) LIMITS
Do not transmit with this radio and ante nna when persons
are within the MPE Radius of the antenna, unless such
persons (vehicle occupants or bystanders, for example) are
shielded from the antenna field by a metallic barrier (such
as the user’s vehicle rooftop). The MPE Radius is the
minimum distance from the antenna axis that ALL persons
should maintain in order to avoid RF exposure higher than
the allowable MPE level set by the FCC.
WARNING
4
Failure to observe these limits may
allow those within the MPE radius to
experience RF radiation absorption
which exceeds the FCC maximum
permissible exposure (MPE) limit. It
is the responsibility of the installer to
ensure that the maximum permissible
exposure limits are observed at all
times during radio transmission. The
installer is to ensure that no
bystanders come within the radius of
the maximum permissible exposure
limits shown below.
1.1.1 Determining MPE Radius
The Maximum Permissible Exposure Radius has been
estimated to be a radius of about 6.3 inc hes (or 16 cm) for a
5 dBi gain antenna, and 11.25 inches (or 28.5 cm) for a 10
dBi gain antenna per OET bulletin 65 of the FCC. This
estimate is made using the maximum capable power of the
radio and a maximum 50% transmit duty cycle.
1.2 SAFETY TRAINING INFORMATION
The DB800 generates RF
electromagnetic energy during transmit
mode. This radio is designed for and
classified as “Occupational Use Only”
meaning it must be used only during the
course of employment by individuals
aware of the hazards and the ways to
minimize such hazards. This radio is
NOT intended for use by the “General
Population” in an uncontrolled
WARNING
environment. It is the responsibility of
the installer to ensure that the
maximum permissible exposure limits
are observed at all times during radio
transmission. The installer is to ensure
that no bystanders come within the
radius of the maximum permissible
exposure limits.

This radio has been tested and complies with the FCC RF
exposure limits for “Occupational Use Only.” In additio n,
this M/A-COM radio complies with the following Standards
and Guidelines with regard to RF energy and
electromagnetic energy levels and evaluation of such levels
for exposure to humans:
• FCC OET Bulletin 65 Edition 97-01 Supplement C,
Evaluating Compliance with FCC Guidelines for
Human Expo sure to Radio Freque ncy Electromagne tic
Fields.
• American National Standards Institute (C95.1 – 1992),
IEEE Standard for Safety Levels with Respect to
Human Expo sure to Radio Freque ncy Electromagne tic
Fields, 3 kHz to 300 GHz.
• American National Standards Institute (C95.3 – 1992),
IEEE Recommended Practice for the Measurement of
Potentially Hazardous Electromagnetic Fields – RF and
Microwave.
1.3 TRANSMITTER HAZARDS
The installer should be aware of
certain hazards common to the
operation of vehicular radio
transmitters. A list of several possible
WARNING
hazards is given:
6
1. Explosive Atmospheres – Just as it is dangerous to
fuel a vehicle with the motor running, similar hazards
exist when operating a vehicular radio. Be sure to turn
the radio off while fueling a vehicle. Do not carry
containers of fuel in the trunk of a vehicle if the radio is
mounted in the trunk.
Areas with potentially explosive atmospheres are
often, but not always, clearly marked. Turn OFF
your radio when in any area with a potentially
explosive atmosphere. It is rare, but not impossible
that the radio could generate sparks.
2. Interference to Vehicular Electronic Systems –
Electronic fuel injection systems, electronic anti-skid
braking systems, electronic cruise control systems, etc.,
are typical electronic systems that can malfunction due
to the lack of protection from radio frequency energy
present when transmitting. If the vehicle contains such
equipment, consult the dealer and enlist their aid in
determining the expected performance of electronic
circuits when the radio is transmitting.
3. Dynamite Blasting Caps – dynamite blasting caps
may be caused to explode by operating a radio within
500 feet of the blasting caps. Always obey the “Turn
Off Two-Way Radios” signs posted where dynamite is
being used.
