Warnings, Cautions and Notes
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

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 7 feet from a properly installed, externally-mounted antenna.
• Install mobile antennas at the center of the roof or the center of the trunk
deck per specific guidelines and instructions in the Radio Installation
Manual. These mobile antenna installation guidelines are limited to metal
body vehicles.
Use only the Motorola-approved, supplied antenna or a Motorolaapproved replacement antenna. Use of non-Motorola-approved antennas,
modifications, or attachments could damage the radio and may violate FCC
regulations.
Compliance and Control Guidelines and Operating Instructions for Mobile
Two-Way Radios Installed as Fixed Site Control Stations
If mobile radio equipment is installed at a fixed location and operated as a control
station or as a fixed unit, the antenna installation must comply with the following
requirements in order to ensure optimal performance and compliance with the RF
energy exposure limits in the standards and guidelines listed in the
Communication Commission Regulations
section.
• The antenna should be mounted outside the building on the roof or a tower if
at all possible.
• As with all fixed site antenna installations, it is the responsibility of the licensee to
manage the site in accordance with applicable regulatory requirements and may
require additional compliance actions such as site survey measurements, signage,

MICOM-2ES/2RS/2TS ALE Supplement to Owner’s Guide
New ALE Features
This section covers the new ALE features that meet the requirements of
MIL-STD-188-141B. This includes a description of selective calling features, and
operating instructions for the various types of ALE calls. This includes new call
types, as well as call types already supported under MIL-STD-188-141A but have
been expanded under new version.
Selective Calling
MICOM 2 supports selective calling as standardized in MIL-STD-181-141B and
FED-1075, and therefore has the capability and flexibility to link with one or many
prearranged or as-needed single or multiple stations.
ALE Addressing Method
ALE uses digital addresses to identify stations. The fundamental address element in
the ALE system is the single word: one ALE address word must always contain three
characters (one triplet).
A single ALE word is needed for the basic individual station address (this is called a
basic address). To increase the available range of addresses, basic addresses can be
expanded up to a maximum of 5 words (15 characters): such addresses are called
extended addresses.
The characters that can used in addresses are a subset of the standard Basic 38 ASCII
character set. This subset includes:
• All the capital (upper case) letters (A to Z)
• All the digits (0 to 9)
• Two utility characters:
!" The stuffing symbol @. It can be used to add characters at the end of an
address, so that the resulting length is a whole number of words
(triplets). A receiving station then interprets only the non-stuffing
characters. For example, if the address has 8 characters, add one @ at the
end of the address, whereas for an address with 7 characters, two @
symbols must be added. In special addressing modes, this symbol is
interpreted as an ignore instruction: see additional utilization guidelines
in Table 1.
!" The wildcard symbol ?. It is used to indicate that any character (except
@) is acceptable (this is the equivalent of a don’t mind instruction). See
Table 2 for utilization guidelines in the special addressing modes.
_________________________________________________________________________________________________
6
New ALE Features
In the following sections, “A,” “B,” “C” or “D” indicates any
alphanumeric character other than “@” or “?”.
Note
MICOM 2 has the capacity to store and use 100 addresses of up to 15 characters
each. MICOM 2 will reject addresses longer than 15 characters, and will notify you
with an UFA WRONG message.
Address and Call Types
ALE stations, including the MICOM 2, have the capability and flexibility to link with
one or many prearranged or as-needed single or multiple stations. There are three
general addressing methods:
• Individual station addressing
• Multiple stations addressing, for example, net and group
• Special addressing modes, for example, AllCall, AnyCall, etc.
The following sections explain the addressing modes and how they can be used for
various purposes.
Individual Station Address
The individual station address may contain 1, 2, 3, 4, or 5 words. To enable using
addresses that are not an integer multiple of 3 characters (for example, an address
consisting of 1, 2, 7, 8, 10, …, etc. characters), stuffing can be used: with stuffing,
the last address word includes one or two stuffing symbols in the last position(s) (see
the “stuff-1” and “stuff-2” patterns in Table 1).
The wildcard symbol cannot be included in an individual station address, nor in a call
request to an individual station.

this function is inhibited)

“Selective AllCall” global address: each station with the same last character “A”
stop scanning and listen (unless this function is inhibited
“AnyCall” global address (see also Table 2): all the stations stop scanning and
respond in randomly selected timeslots (unless this function is inhibited)
“Selective AnyCall” address: each station with same last character(s) “A” (or
“B”) stops scanning and responds in a randomly selected timeslot (unless this
function is inhibited), using its own address
“Double selective AnyCall” address: each station with same last characters “AB”
(or “CD”) stops scanning and responds in a randomly selected timeslot (unless
this function is inhibited), using its own address
“Null” address; all the stations ignore this address. The null address intended for
use in test and maintenance, or to create an extra “buffer” timeslot
Net Addresses
The purpose of a net call is to rapidly and efficiently establish contact with multiple
prearranged (net) stations. This is achieved by the use of a single net address.
The net address is actually an additional address assigned in common to all the
stations that are members of a specific net. Its address structure is identical to that
used for individual station addresses (basic or extended, with or without stuffing, as
necessary).
When defining a net, each member station is automatically assigned a timeslot: by
having each station answer a call request in a different timeslot, collisions are
avoided.
Group Addresses
The purpose of a group call is to rapidly and efficiently establish contact with
multiple non-prearranged (group) stations.
To make a group call, a calling ALE station uses a sequence of the actual individual
station addresses of the called stations.
Special Addressing Modes – Use of Wildcards
A “wildcard” is a special character,“?”, that a calling station can use to address
multiple stations with a single call address. The following rules apply:
• The total length of a calling address that includes wildcard(s) must be equal to
that of the called station addresses.
_________________________________________________________________________________________________
8
New ALE Features
• A receiving station will accept a wildcard character as a substitute for the
alphanumeric character in its own address that occupies the same position. This
means that the wildcard character is a substitute for any of 36 characters and
digits (A to Z, 0 to 9) in the Basic 38 character subset.
• Multiple wildcard characters can be used in different positions of the same
address (basic or extended).
See Table 2 for examples of patterns using the “?” wildcard symbol.
