Introduction
1-1. Notational Conventions
Throughout the text in this publication, you will notice the use of warnings, cautions and notes. These
notations are used to emphasize that safety hazard exist, and care must be taken and observed.
Warning
This Warning symbol denotes a hazard. It calls attention to a procedure
or practice that could result in personal injury if not performed correctly.
Caution 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.
Note An operational procedure, practice or condition, etc., which is essential to
emphasize.
Throughout this manual, MICOM-3F, MICOM-3T and MICOM-3R are referred to as MICOM-3.
1-2. Scope of this Manual
This manual includes model/kit information, specifications, disassembly/reassembly procedures,
alignment, troubleshooting, and all theory, schematic diagrams, printed circuit board details and parts
lists for all parts in the equipment described.
Caution This manual is intended for use by experienced technicians who are familiar
with similar types of equipment.

1-3. Federal Communication Commission Regulations
The FCC has established limits for safe exposure to radio frequency (RF) emissions from mobile
two-way radios. The FCC requires manufacturers to demonstrate compliance with RF exposure
limits before mobile two-way radios can be marketed In the U.S. When two-way radios are
approved for occupational/controlled environment exposure limits, the FCC requires users to be
fully aware of, and exercise control over, their exposure. Awareness and control of RF exposure
can be accomplished by education or training through appropriate means such as information
and instructions in user manuals or safety booklets, or other appropriate means. This user safety
booklet includes useful information about RF exposure and helpful instructions on how to
control your RF exposure.
Your Motorola two-way radio is designed and tested to comply with a number of national and
international standards and guidelines (listed below) regarding human exposure to radio frequency
electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits for
occupational/controlled RF exposure environments at usage factors of up to 50% talk-50% listen.
In terms of measuring RF energy for compliance with FCC exposure guidelines, your radio radiates
measurable RF energy only while it is transmitting (during talking), not when it is receiving
(listening) or in standby mode.
Your Motorola two-way radio complies with the following RF energy exposure standards and
guidelines:
• United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2
sub-part J
• American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers
(IEEE) C95.1-1992
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition
• International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
• Ministry of Health (Canada) Safety Code 6: Limits of Human Exposure to Radiofrequency
Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999
• Australian Communications Authority Radiocommunications (Electromagnetic Radiation –
Human Exposure) Standard, 2001
• ANATEL, Brasil Regulatory Authority, Resolution 256 (April 11, 2001: Additional Requirements
for SMR, Cellular and PCS Product Certification.
1-3.1 Compliance and Control Guidelines and Operating Instructions for
Mobile Two-Way Radios Installed in Vehicles
To control your exposure and ensure compliance with the occupational/ controlled environment
exposure limits, always adhere to the following procedures:
• To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button.
Transmit only when people outside the vehicle are at least the minimum lateral distance
away (as shown in table below) from a properly installed, externally-mounted antenna.
The table below lists the minimum lateral distance for bystanders in an uncontrolled environment
from the transmitting antenna at several different ranges of rated radio power for mobile radios
installed in a vehicle.
