The MICOM-2E also meets the EIA-RS152B for shock, vibration and applicable test
procedures, US FCC and Canadian DOC for channel occupancy, spurious, interference and
frequency tolerance. It is manufactured according to the demanding standards of ISO 9000
and EMC (Electromagnetic Compatibility).
Note 1: Values noted as “Typical” are valid over 90% or more of the frequency range.

Information for Safe, Efficient Operation
Exposure to Radio Frequency Energy
In August 1996, the Federal Communications Commission (FCC)
adopted updated RF energy exposure guidelines for wireless products
regulated by the FCC. Those guidelines are consistent with the safety
standards* previously set by both U.S. and international standards
bodies. The design of your Motorola two-way radio complies with the
FCC guidelines and these standards.
*American National Standards Institute (C95.1 - 1992);
*National Council on Radiation Radiation Protection and Measurements
(NCRP-1986);
*International Commission on Non-Ionizing Radiation Protection
(ICNRP- 1986)
To assure optimal radio performance and to insure that exposure to RF
energy is within the guidelines in the above  standards, properly install
antennas externally on the vehicle, following recommended installation
procedures.
Transmit only when people inside or outside the vehicle are 1 to 3 feet
away from the properly installed, externally mounted antenna; distance
guidelines for the different power levels are summarized in the table
below:
Rated power of Distance of people from
Vehicle-Mounted Radio Transmitting antenna
15 Watts or less 1 Foot
16 to 50Watts 2 Feet
More than 50Watts 3 Feet

Potentially Explosive Atmospheres
Turn your radio OFF when in any area with a potentially
explosive atmosphere, unless it is a type especially qualified
for such use (for example, FMRC Approved). Sparks in such
areas could cause an explosion or fire resulting in bodily injury
or even death.
Areas with potentially explosive atmospheres are often, but not always,
clearly marked. They include fuelling areas such as below deck on
boats, fuel or chemical transfer or storage facilities; areas where the air
contains chemicals or particles, such as grain, dust, or metal powders;
and any other area where you would normally be advised to turn off
your vehicle engine.
Blasting Caps and Areas
To avoid possible interference with blasting operations, turn
your radio OFF near electrical blasting caps or in a “blasting
area” or in areas posted: “Turn off two-way radio”. Obey all
signs and instructions.

Guidelines and Warnings
Symbols
The Warning symbol denotes a hazard. It calls attention to a
procedure or practice that could result in personal injury if not
performed correctly.
The Caution symbol denotes a hazard. It calls attention to a
procedure or practice that could result in damage to or
destruction of part or all of the product if not performed
correctly.
Installation Safety Warning
Consider the occupants’ safety when you choose a location for the
radio. Do not mount the radio overhead or on a side wall unless you
take special precautions.
If someone were to remove the radio and does not replace it properly,
then a road block could bump the radio loose and the falling radio, could
in some circumstances, cause serious injury to the driver or a
passenger.  In a crash, even when properly installed, the radio could
break loose and become a dangerous projectile.
If you have to mount the radio overhead or on a sidewall, give it the
added protection of a retaining strap.
Operational Safety Warning
For vehicles equipped with a electronic anti-skid systems, see
“ANTI-SKID BRAKING PRECAUTIONS” publications,
Motorola No. 68P81109E34.
