Service Manual

Manual&Scan&

I hope this service manual is of use to you. Motorola does

not make this available as a PDF and all other available

copies are of poor quality.

Each page is captured at 600 DPI, and as 24-bit color, 8-

bit grayscale or black and white and at the proper page

size, up to 11x34 inches in many cases. OCR has been

preformed on the document, even on the large pages. The

document is condensed into one single PDF with text

overlay. You should be able to print the larger sheets on

11x17 or tile them onto 8.5x11 if needed.

Please do not charge for access to this, or put it on a

pay-wall site. Please don’t pay for access to any such

sites, they are against the ethos of hacking, and it only

encourages them to profit off the hard work of others which

has been shared openly. Please don’t change

this/recompress it; this defeats the point of capturing

this at high resolution.

If something is incorrect here, or unreadable please reach

out; I likely have the original lossless compressed images.

In the final PDF that’s color or grayscale will be JPEG

2000 format with highest quality selected. B&W images will

be compressed using CCITT Group 4. This is quite close to

the source material, but there may be some artifacts due to

lossy compression. If there’s a choice between file size

and image quality, image quality will win. It’s 2021 and

storage and bandwidth is cheap.

This was captured on a Canon DR-G2140 scanner which is ~

7500 USD unit circa 2021. You may note some artifacts and

lines in on the scans, these are due to scratches on the

sensor glass, and are minor. The replacement glass is

about 250 USD if you’re feeling generous :-)

If you have a hard to find/out of print manual and would

like to make it available please reach out, I may be able

to scan and return it to you.

Thank you,

FOR USE IN HAZARDOUS ATMOSPHERES

Factory Mutual Non-tncendive and Intrinsically Safe Approved Models

The SYSTEMS SABER and Ill, and SABER ATS portable radios must be properly equipped with aFactory

Mutual (FM) Corporation approved battery to be considered "intrinsically safe."

The FM options for the radio provide alabel which lists the Class/Division/Group, verifies the radio as being

FM approved, and states the type of battery to be used with the radio.

The intrinsically safe rating by Factory Mutual states that electrical equipment is incapable of releasing suffi-

cient electrical or thermal energy, under normal or abnormal operating conditions, to cause ignition of specific

hazardous atmospheres designated on the radio label.

WARNING

Substitution of components may impair the intrinsic safety of the radio.

Note

Radios must be shipped from the Motorola factory equipped with the hazardous

atmosphere option; they cannot be modified in the field.

Failure to use the radio with an approved battery will negate the FM approval. Factory Mutual approved

radios can be used in those applications requiring reliable, two-way hand-held radios in the listed specific haz-

ardous atmospheres. Motorola approved equipment and accessories are listed in the approval guide published

yearly by Factory Mutual Corporation.

ASSEMBLY

.SERVICING MAJOR SUBASSEMBLIES

a. Baseplate

All repairs to the baseplate assembly can, and

should, be made with the radio chassis inside the

radio.

After the slotted-spanner nuts are loosened, the

baseplate is held in place by the power contact

screw.

The retainers holding the slotted-spanner nuts in

place are not reusable. Replacement of the retain-

ers requires special insertion procedures; refer to

the instruction sheet provided with the slotted-

spanner nut kit.

The "o-ring" portion of the elastomer seal must be

fully seated on the threaded bushing before the

baseplate is reassembled (the bushing is part of

the housing assembly).

.Housing Assembly

The housing assembly includes many parts that

are not replaceable or repairable.

The insulator on the universal connector can, and

should, be replaced if the old insulator has been

torn. When replacing the insulator take care to

keep it out of the main seal o-ring's seating area.

The PTT lever can be replaced by prying out the

old part with asoft plastic tool. The plastic housing

around the lever may be damaged if aharder tool

is used.

c.Control Top Panel

The control top panel is fastened to the frame by

the on/off/volume and frequency switches, and two

self-tapping screws; it should be removed from the

frame only if absolutely necessary. If repair is

required, always start the screws into the control

top panel by hand before tightening them with a

torque wrench; this will help avoid cross-threading

and stripping of the plastic panel.

The on/off/volume and frequency knobs are 2-part

kits; each kit consists of aknob and an insert. Once

an insert is removed, it cannot be used again;

therefore, remove an insert only if the on/off/vol-

ume contro! or frequency switch must be replaced,

or if the control top must be removed from the

frame.

d. LCD/Speaker Bracket Assembly

The SYSTEMS SABER radio's LCD assembly

and/or controller board can be replaced, but the com-

ments and cautions in this manual must be strictly fol-

lowed.

(1) Removing the LCD Assembly and Controller

Board:

(a) Carefully unplug the interconnect and speaker/

microphone flexible circuits from the radio.

(bo) (SYSTEMS SABER Ill only) After ensuring that all

static safeguards are in effect, turn the LCD/speak-

er bracket assembly over (display facing up), insert

athin plastic blade (such as atuning wand)

between the top edge of the keypad membrane

switch and the LCD bezel, and break the adhesive

bond between the bezel and the membrane switch.

and, using athin-bladed screwdriver, gently pry the

controller board away from the two speaker bracket

tabs (the tabs next to the speaker).

(d) Place your middle finger on. the top center tab and

your thumb on the bottom left tab of the controller

board, and gently pry the shield/controlier board

assembly away from the front shield.

(e) Gently lift the shield/controller board assembly

away from the front shield, rotating it around the

front shield until the keypad flexible circuit lies flat

and the display is facing upward.

(f) Insert athin-bladed screwdriver between the plug

on the keypad flexible circuit and the controller

board, and gently pry upward on the plug until it is

free from the board.

(g) With the controller board facing upward, locate the

retaining tab on the top edge of the controller board

and deflect the shield near the tab while lifting the

board up and away from the shield. The circuit

board and interconnect flexible circuit can then be

pulled forward and out.

(g) Unplug the interconnect flexible circuit from the

controller board.

(2) Replacing the LCD Assembly (SYSTEMS

SABER Iil Only):

(a) With the display facing downward, locate and care-

fully straighten the six bent-over metal tabs holding

the LCD assembly to the the controller board, then

separate the LCD assembly from the board.

(b) Inspect the two rows of LCD contacts on the con-

troller board for damage and/or foreign material,

and clean if necessary.

for fingerprints or other foreign material. Clean, if

necessary, only with water-activated optical wipes.

(d) After first making sure that the lens shipping pro-

tection has been removed, insert the new LCD

assembly so that the viewing side of the display

shows through the window in the bezel, and the

seal on the display fits into the corresponding

recess in the bezel.

(e) Insert the LCD lightpipe into the bezel with the

clear side facing the back of the display.

(f) Position the elastomers along the top and bottom

edges of the LCD lightpipe so that the conductive

black dots on the elastomers connect the LCD to

the contacts on the controller board.

(g) Place the controller board over the metal tabs on

the LCD bezel and, while applying firm, even pres-

sure to fully seat the LCD assembly into the con-

troller board, bend all the tabs inward.

e. Backshield Assembly

¢Before removing the backshield, ensure that all

Static electricity safeguards are in place.

*For best results, loosen/tighten all four screws light-

ly before loosening/tightening any single screw

completely.

*The backshield screws are held captive in the

shield after being loosened.

f. Circuit Boards and Modules

*All modules plug into sockets on the main circuit

board.

Some modules are fastened to the main board and

frame with screws; remove these screws before

attempting to unpiug amodule. Never substitute

any screw.

Several of the modules are designed to be

removed with astandard DIP extractor tool (OK-1

or equivalent). Always use the extractor tool when

removing these modules to avoid damaging their

leads.

Some modules have guide pins to assist in inser-

tion or removal. Pressure may be applied to these

guide pins to aid removal of amodule if, and only if,

it is distributed evenly over all guide pins on the

module. Applying all the force to asingle guide pin

will cause severe damage to the module.

The secure module (U900) is not serviceable.

Before reinserting any module, always check its

leads for damage. Gently straighten any leads that

may be bent; replace any modules with severely

damaged leads.

Before reinserting reference oscillator module

U301 into the main circuit board, be certain that its

squared (pin 1) corner is correctly oriented per the

main circuit board component layout diagram.

When electrically testing and/or probing the main

circuit board with the back shield removed, always

use the three finger screws on the SYSTEMS

SABER housing eliminator service aid to provide

grounding to VCO synthesizer module U300 (two

places), and the rf ground clip (one place).

When removing the main circuit board from the

frame assembly, do the following:

Remove the back shield assembly.

2. Unplug the PTT/controls flexible circuit.

3. Remove the two power amplifier module

(U202) screws from the frame.

4. Remove secure module U900.

5. Remove the two main compression connector

screws.

6. Lift the board at the bottom and pull out from

under the control top panel.

The rf and ground contacts at the top of the main

circuit board are exposed when the board is

removed from the frame. Special care must be taken

to avoid accidental damage to these contacts.

.Frame Assembly

The tapped tabs on the frame can be stripped if

excessive screw tightening torques are used (see

Torque Specifications table). The frame is not

repairable.

If you must lift or remove the PTT/controls flex cir-

cuit for any reason, do not readhere it to the frame;

the flex must be replaced.

.Dual-Function Switch (S801) and

Actuator Assembly

Before removing the switch, remove the knob by

.gently separating the two arms of the switch brack-

et (located between the switch and the main O-ring

seal) and pulling upward on the knob.

Before reinserting the knob, ensure that the slot in

the switch is properly aligned with the blade on the

knob's shaft.

When the knob is properly inserted, the arms of

the switch bracket will snap into position (approxi-

mately 0.2 inches apart), the knob will not be loose

in the switch bracket, and the bracket will hold the

switch firmly against the inside of the top control

panel. If this is not the case, replace the switch

bracket.

3. REASSEMBLY

Reassemble the radio in the reverse order of dis-

assembly, referring to "SERVICING MAJOR SUB-

ASSEMBLIES" (Section 2) and making certain:

that the speaker/microphone connector and the

LCD interconnect header are correctly aligned to

the main circuit board so that no twisting or pinch-

ing of the flexible circuit occurs when the speaker

bracket is reattached to the frame assembly.

that all pads are correctly aligned.

that the two extended tabs at the top of the speak-

er bracket are properly inserted into the slots

between the frame and the control top panel.

to tighten all hardware loosened or removed during

disassembly per the torque specifications listed in

the Torque Specifications table. Use recommended

torque driver (Motorola RSX4043A Rototorg Tool

or equivalent).

that there is no foreign material on the main O-ring

or stud seals.

CAUTIONS

Inspect_the frame stud seals and the top

pane! O-ring and replace if any damage

exists

to properly orient the completed frame assembly

before inserting it into the radio housing.

that the PTT switch and monitor button are not

depressed while the frame is being inserted into

the housing.

PERFORMANCE TESTS

1. TEST MODE

When the SYSTEMS SABER radio is operating in

atrunking environment, it operates with aspecific

identity within an assigned system. Given commands

from that system, the radio's internal microcomputer

controls such functions as rf channel selection, trans-

mitter key-up, and receiver muting.

However, when the unit is on the bench for test-

ing, it is removed from this trunking environment. It

cannot receive commands from its system and, there-

fore, the internal microcomputer will not key the

transmitter or unmute the receiver. This prevents test-

ing the radio in the normal manner unless it has been

programmed on one or more conventional (non-trunk-

ed) channels. On one of these channels the unit may

be tested in the normal mode allowed by the channel's

programmed modes; for example, tone Private-Line®

(TPL), Digital Private-Line™ (DPL), etc.

To allow for testing the radio in amore generic

fashion, special test routines that allow manual control

of the various modes of the unit have been provided

for in the test mode called Air Test, which allows one

to test various parameters without having to disas-

semble the radio. If adjustments are needed, the use

of the field programmer, described in the SYSTEMS

SABER Radio Service Software User's Guide, will be

required.

To enter the Air Test mode, connect the equip-

ment as shown in Figure 1, then do the following:

a. Turn the radio off.

b. Apply 7.5 volts to the radio battery contacts.

c. Connect the radio to the RTX4005B portable test

set via the test cable.

d.. Place the transmit mode switch on the test set in

the CONT (transmit) position.

e. Press and hold down the monitor button on the

side of the radio.

f. Turn the radio on and continue to hold down the

monitor button for two seconds.

g. Turn the transmit mode switch on the test set to

the OFF position.

NOTE

¢The unit will not transmit until the transmit

mode switch has been turned off and then back

to one of the transit positions.

«Do not change modes or channels during Air

Test while in the transmit mode.

¢To exit Air Test turn the radio off.

Figure 1. Air Test Setup

Air Test allows the testing of any combination of ten frequency pairs, two transmitter power levels, six modu-

lation modes, and three receiver squelch modes. Selection of afrequency pair is done by rotating the rotary

selector switch on top of the radio. See Table 1for alisting of the Air Test transmit and receiver frequencies, and

transmitter power output levels associated with the rotary selector switch.

To change modulation/squeich modes, press one of the "side button" switches on the side of the radio: press-

ing the button closest to the front of the radio (SB1) will increment the mode; pressing the button closest to the

back of the radio (SB2) will decrement the mode. See Table 2for alisting on the various modulation/squelch

modes.

As the modulation/squelch mode is changed, aone- to six-"bonk'" audio tone will be heard, and the display

will indicate the mode by displaying the squelch mode number from one to six.
