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

Warnings, Cautions and Notes

Electromagnetic Interference/Compatibility

Note

Facilities

Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or otherwise configured for electromagnetic compatibility. It may be necessary to conduct compatibility testing to determine if any electronic equipment used in or around vehicles or near fixed site antenna is sensitive to external RF energy or if any procedures need to be followed to eliminate or mitigate the potential for interaction between the radio transmitter and the equipment or device.

To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.

Vehicles

To avoid possible interaction between the radio transmitter and any vehicle electronic control modules, for example, ABS, engine, or transmission controls, the radio should be installed only by an experienced installer and that the following precautions be used when installing the radio:

1.Refer to the manufacturer's instructions or other technical bulletins for recommendations on radio installation.

2.Before installing the radio, determine the location of the electronic control modules and their harnesses in the vehicle.

3.Route all radio wiring, including the antenna transmission line, as far away as possible from the electronic control units and associated wiring.

Driver Safety

Check the laws and regulations on the use of radios in the area where you drive. Always obey them.

When using your radio while driving, please:

•Give full attention to driving and to the road.

•Pull off the road and park before making or answering a call if driving conditions so require.

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.

Table 1. Use of “@” Stuffing Symbol

Pattern	Interpretation

A B C “Standard” 3-character address word, shown here for reference. Only the station with this address stops scanning and responds

A B @ “Stuff-1” reduced address field, used to add characters “A, B” at the end of the address

A @ @ “Stuff-2” reduced address field, used to add character “A” at the end of the address

@ ? @ “AllCall” global address (see also Table 2): all the stations stop and listen (unless this function is inhibited)

_________________________________________________________________________________________________ 7

MICOM-2ES/2RS/2TS ALE Supplement to Owner’s Guide

Table 1. Use of “@” Stuffing Symbol (Cont.)

Pattern	Interpretation

@A @ “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)

@@ A “Selective AnyCall” address: each station with same last character(s) “A” (or

	@ B@	“B”) stops scanning and responds in a randomly selected timeslot (unless this
		function is inhibited), using its own address
	(option)
	@ A B	“Double selective AnyCall” address: each station with same last characters “AB”
	@ C D	(or “CD”) stops scanning and responds in a randomly selected timeslot (unless
		this function is inhibited), using its own address
	(option)
	@ @ @	“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.

		Table 2. Use of “?” Wildcard Symbol
	Pattern	Interpretation
	A B C	“Standard” 3-character address, shown here for reference. All the characters in
		this word must be evaluated
	A B ?	“Standard” “wild-1” address word. Indicates that only the positions occupied by
	A ? C	other characters (“A” and “B”) need be evaluated: the position occupied by the
	? B C	“?” symbol can be ignored (ignored in this context means that any valid character
		is accepted)
	A ? ?	“Standard” “wild-2” address word. Indicates that only the position occupied by an
	? B ?	character (“A”, “B” or “C”) need be evaluated: the positions occupied by the “?”
	? ? C	symbols can be ignored
	? ? ?	“Standard” “wild-3” address word. Indicates that all of the three positions in this
		word can be ignored
	A B @	“Stuff-1” reduced address field, shown here for reference. Only the first two
		characters in this word must be evaluated
	A ? @	“Wild-1” “stuff-1” address. Only the character “A” or “B” in this word must be
	? B @	evaluated
	? ? @	“Wild-2” “stuff-2” address. Only the character “A” or “B” in this word must be
		evaluated
	A @ @	“Stuff-2” reduced address field, shown here for reference. Only the first character
		in this word must be evaluated
	? @ @	“Wild-1” “stuff-2” address. Only the first character in this word must be
		evaluated, and is ignored
	@ A B	“Double selective AnyCall” address word, shown here for reference: only the last
		two characters in this word must be evaluated
	@ A ?	“Double selective AnyCall” “wild-1” address word: only the middle character
		“A” in this word must be evaluated
	@ ? B	Not permitted. Use “selective AnyCall”
	@ ? ?	Not permitted. Use “global AnyCall”
