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

MICOM-2E-ALE Owner’s Manual
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.
xv
MICOM-2E-ALE Owner’s Manual
It is mandatory that radio installation in vehicles fueled by
liquefied petroleum gas conform to the following standard:
National Fire Protection Association standard NFPA 58 applies to radio
installations in vehicles fueled by liquefied petroleum (LP) gas with LP
gas container in the trunk or other sealed-off space within the interior of
the vehicles. The standard requires that:
1. Any space containing radio equipment shall be isolated by a seal
from the space in which the LP-gas container and its fittings are
located.
2. Remote (outside) fitting connections shall be used.
3. The container space shall be vented to the outside.
Vehicles With an Air Bag
An air bag inflates with great force. Do not place objects,
including portable or mobile two-way radios, in the area over
the air bag or in the air bag deployment area. If improperly
installed or placed wireless equipment is in the air bag
deployment area and the air bag inflates, serious injury could
result.
Installation of the MICOM-2E radio should be performed by a
professional installer/technician qualified in the requirements for such
installations. An air bag’s size, shape and deployment area can vary by
vehicle make, model and front compartment configuration (e.g., bench
seat vs. bucket seat).
Contact the vehicle manufacturer’s corporate headquarters, if
necessary, for specific air bag information for the vehicle make, model
and front compartment configuration involved in your communication
equipment installation.
xvi
Information for Safe, Efficient Operation
Restrictions
Because this radio contains a transmitter, federal law prohibits
unauthorized, non-licensed personnel from adjusting or maintaining it. If
any operational difficulties should arise while using this product, report
them to authorized service personnel as soon as possible.
Do not attempt any unauthorized modification to the radio.

• 1 kW amplifier
• Antennas and grounding
• Data/fax modems
• CW key and headphones
• External speaker
Transmitter Features
The maximum output power of the transmitter is 125 W PEP (Peak
Envelope Power), with an average transmission duty cycle of 1 to 4,
thus enabling even the CW (Continues Wave) signal to be transmitted at
the maximum available power. Output power can be preprogrammed to
one of the four possible levels: 25W, 62.5W, 100W and 125W. Accurate
sensors are used to keep the output power within the nominal value.
The transmitter includes thermal protections. If, for any reason, the
transmitter internal temperature exceeds the maximum permitted
temperature, the output power is automatically reduced to avoid any
fault due to excessive heat.
Mismatch protection is also included. If the VSWR (Voltage Standing
Wave Ratio) rises to more than 2:1, the transmitter will be inhibited in
order to avoid any damage and a message will be displayed.
2
Receiver Features
The radio utilizes Digital Signal Processing for implementing most of the
reception functions like demodulations, narrow filtering, automatic gain
control, noise blanking, and squelch.
The automatic digital noise blanker is activated whenever repetitive
noise (e.g. ignition spikes) is encountered in the received signal. The
digital syllabic (speech identifier) squelch is activated whenever speech
is identified, thus opening the audio path. However, if speech is not
received, the audio path is muted, thus preventing background noise
from disturbing the operator.
Frequency Sources
Two types of frequency sources are available for the MICOM-2E radio.
The standard 0.6 PPM DTCXO frequency source which assures a
frequency stability of better than ±18 Hz. For frequencies lower than
10 MHz, it assures a frequency stability of better than ±6 Hz.
When higher frequency stability is required, the G478 0.1 PPM OCXO
frequency source can be ordered. It will assure a frequency stability of
better than ±3 Hz at 30 MHz.
Introduction
Power Source
The radio is designed for 13.8 V ± 20% negative-ground operation and
may be connected to a standard 12 V battery.
CW Keying Operation
When the CW key is pressed, the radio transmits a continuous wave (at
the full programmed power) and stops transmission when the key is
released.
CW keying operation is enabled by connecting the Morse key, between
CW (pin #10) and ground (pin #18) at the accessory connector. If you
wish to operate CW keying with external headphones, the S809
Interface can be used, thus enabling a standard PL55 headphone and
standard PL99 Morse key to be connected to the accessories
connector.
