WARNINGS
WARNINGS 
• 
Do not operate radio communications equipment in 
a hazardous atmosphere unless it is a type especially 
qualified for such use (e.g., FMRC Approved). An 
explosion or fire may result. 
• 
Do not operate an FMRC Approved Product in a 
hazardous atmosphere if it has been physically 
damaged (e.g., cracked housing). An explosion or 
fire may result. 
• 
Do not replace or charge batteries in a hazardous 
atmosphere. Contact sparking may occur while 
installing or removing batteries and cause an 
explosion or fire. 
• 
Do not replace or change accessories in a hazardous 
atmosphere. Contact sparking may occur while 
installing or removing accessories and cause an 
explosion or fire. 
• 
Do not operate an FMRC Approved Product unit in a 
hazardous location with the accessory contacts 
exposed. Keep the connector cover in place when 
accessories are not used. 
• 
Turn a radio off before removing or installing a 
battery or accessory. 
• 
Do not disassemble an FMRC Approved Product unit 
in any way that exposes the internal electrical 
circuits of the unit. 
• 
Radios must ship from the Motorola manufacturing 
facility with the hazardous atmosphere capability 
and FM Approval labeling. Radios will not be 
“upgraded” to this capability and labeled in the 
field.
•A modification changes the unit’s hardware from its 
original design configuration. Modifications can 
only be made by the original product manufacturer 
at one of its 
FMRC-audited manufacturing facilities.

WARNINGS
Repair of FMRC Approved Products
REPAIRS FOR MOTOROLA PRODUCTS WITH FMRC APPROVAL ARE 
THE  RESPONSIBILITY OF THE USER.
You should not repair or relabel any Motorola- manufactured 
communication equipment bearing the FMRC Approval label (“FMRC 
Approved Product”) unless you are familiar with the current FMRC 
Approval standard for repairs and service (“Class Number 3605”).
You may want to consider using a repair facility that operates under 
3605 repair service approval.
WARNINGS
FMRC’s Approval Standard Class Number 3605 is subject to change at 
any time without notice to you, so you may want to obtain a current 
copy of 3605 from FMRC. Per the December 1994 publication of 3605, 
some key definitions and service requirements are as follows:
Repair
A repair constitutes something done internally to the unit that would 
bring it back to its original condition—Approved by FMRC. A repair 
should be done in an FMRC Approved facility.
Items not considered as repairs are those in which an action is 
performed on a unit which does not require the outer casing of the 
unit to be opened in a manner which exposes the internal electrical 
circuits of the unit. You do not have to be an FMRC Approved Repair 
Facility to perform these actions.•Failure to use an FMRC Approved Product unit with an 
FMRC Approved battery or FMRC Approved accessories 
specifically approved for that product may result in the 
dangerously unsafe condition of an unapproved radio 
combination being used in a hazardous location.
•Unauthorized or incorrect modification of an FMRC 
Approved Product unit will negate the Approval rating 
of the product.
•Incorrect repair or relabeling of any FMRC Approved 
Product unit could adversely affect the Approval 
rating of the unit.
•Use of a radio that is not intrinsically safe in a 
hazardous atmosphere could result in serious injury 
or death.

Relabeling
The repair facility shall have a method by which the replacement of 
FMRC Approval labels are controlled to ensure that any relabeling is 
limited to units that were originally shipped from the Manufacturer 
with an FM Approval label in place. FMRC Approval labels shall not be 
stocked by the repair facility. An FMRC Approval label shall be ordered 
from the original manufacturer, as needed, to repair a specific unit. 
Replacement labels may be obtained and applied by the repair facility, 
provided there is satisfactory evidence that the unit being relabeled 
was originally an FMRC Approved unit. Verification may include, but 
is not limited to: a unit with a damaged Approval label, a unit with a 
defective housing displaying an Approval label, or a customer invoice 
indicating the serial number of the unit and purchase of an FMRC 
Approved model.
Do Not Substitute Options or Accessories
The Motorola communications equipment certified by Factory Mutual 
is tested as a system and consists of the FM Approved portable, FM 
Approved battery, and FM Approved accessories or options, or both. 
This FM Approved portable and battery combination must be strictly 
observed. There must be no substitution of items, even if the substitute 
has been previously Approved with a different Motorola 
communications equipment unit. Approved configurations are listed 
in the FM Approval Guide published by FMRC, or in the product FM 
Supplement. This FM Supplement is shipped from the manufacturer 
with the FM Approved radio and battery combination. The Approval 
Guide, or the Approval Standard Class Number 3605 document for 
repairs and service, can be ordered directly from Factory Mutual 
Research Corporation located in Norwood, Massachusetts.

Replacement Parts 
Ordering When ordering replacement parts or equipment information, the 
complete identification number should be included. This applies to all 
components, kits, and chassis. If the component part number is not 
known, the order should include the number of the chassis or kit of 
which it is a part, and sufficient description of the desired component 
to identify it.

Introduction

GeneralThis manual includes all the information necessary to maintain peak 
product performance and maximum working-time. This detailed-level 
of service (component-level) is typical of some service centers, self-
maintained customers, and distributors. 
This manual is to be used in conjunction with the ASTRO Digital 
SABER Portable Radios Basic Service Manual (Motorola part number 
68P81076C05), which helps troubleshooting a problem to a particular 
board. Conduct the basic performance checks first. This will verify the 
actual need for analyzing the radio and help pinpoint the functional 
problem area. In addition, the technician will become familiar with 
the radio test mode of operation, which is a helpful tool. If any basic 
receive or transmitter parameters fail, then the radio should be aligned 
per the radio alignment procedure.
Included in other areas of this manual are functional block diagrams, 
detailed theory of operation, troubleshooting charts and waveforms, 
schematics, and parts list. The technician should be very familiar with 
these sections to aid in deducing the problem circuit. Also included are 
component location diagrams to aid in locating individual circuit 
components and some IC diagram, which point out some convenient 
probe points.
The theory of operation sections of this manual contain detailed 
descriptions of operations of many circuits. Once the area of the 
problem is located, it would be strongly advisable to review the 
operation of the circuit pertaining to the troubleshooting flow chart.
