SAFETY INFORMATION

Read this information before using the radio.

PRODUCT SAFETY AND RF EXPOSURE FOR PORTABLE TWO-WAY RADIOS.

This document provides information and instructions for the safe and efficient operation of Motorola

Portable Two-Way Radios.

RF Energy Exposure Awareness and Control Information and Operational

Instructions for Occupational Use

Note:This Radio is intended for use in occupational/controlled applications, where users have been

made aware of the potential for exposure and can exercise control over their exposure. This radio

device is NOT authorized for general population, consumer or similar use.

This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide

communications between two or more users over a distance. It uses radio frequency (RF) energy or

radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other forms

include, but are not limited to, sunlight and x-rays. RF energy, however, should not be confused with

these other forms of electromagnetic energy, which when used improperly, can cause biological

damage. Very high levels of x-rays, for example, can damage tissues and genetic material.

Experts in science, engineering, medicine, health, and industry work with organizations to develop

standards for safe exposure to RF energy. These standards provide recommended levels of RF

exposure for both workers and the general public. These recommended RF exposure levels include

substantial margins of protection.

All Motorola two-way radios are designed, manufactured, and tested to ensure they meet

government-established RF exposure levels. In addition, manufacturers also recommend specific

operating instructions to users of two-way radios. These instructions are important because they

inform users about RF energy exposure and provide simple procedures on how to control it.

Please refer to the following websites for more information on what RF energy exposure is and how to

control your exposure to assure compliance with established RF exposure limits:

http://www.fcc.gov/oet/rfsafety/rf-faqs.html

http://www.osha.gov/SLTC/radiofrequencyradiation/index.html

Federal Communication Commission (FCC) Regulations (US markets only)

The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for portable

two-way radios before they can be marketed in the U.S. When two-way radios are used as a

consequence of employment, the FCC requires users to be fully aware of and able to control their

exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a

product label directing users to specific user awareness information. Your Motorola two-way radio has

a RF Exposure Product Label. Do not remove this RF Exposure Label from the device. Also, your

Motorola user manual, or separate safety booklet includes information and operating instructions

required to control your RF exposure and to satisfy compliance requirements.

iv

Compliance with RF Exposure Standards

Your Motorola two-way radio is designed and tested to comply with a number of national and

International standards and guidelines (listed below) for 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 operating duty factors of up to 50% talk-

50% listen and is authorized by the IEEE/ICNIRP for occupational use only.

In terms of measuring RF energy for compliance with these exposure guidelines, your radio

generates measurable RF energy only while it is transmitting (during talking), not when it is

receiving (listening) or in standby mode.

Note: The approved batteries, supplied with this radio, are rated for a 5-5-90 duty cycle (5% talk–5%

listen–90% standby), even though this radio complies with IEEE/ICNIRP occupational exposure limits

at usage factors of up to 50% talk.

Your Motorola two-way radio complies with the following RF energy exposure standards and

guidelines:

●United States Federal Communications Commission, Code of Federal Regulations; 47 CFR 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 2003

●ANATEL ANNEX to Resolution No. 303 of July 2, 2002 "Regulation of limitation of exposure to

electrical, magnetic and electromagnetic fields in the radio frequency range between 9 KHz and

300 GHz" and "Attachment to resolution # 303 from July 2, 2002"

RF Exposure Compliance and Control Guidelines and Operating Instructions

To control your exposure and ensure compliance with the occupational/controlled environment expo-

sure limits, always adhere to the following procedures:

Guidelines:

●User awareness instructions should accompany device when transferred to other users.

●Do not use this device if the operational requirements described herein are not met.

Operating Instructions

●Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-To-

Talk (PTT) button. To receive calls, release the PTT button.

Transmitting 50% of the time, or less, is important because this radio generates measurable RF

energy exposure only when transmitting (in terms of measuring for standards compliance).

●When worn on the body, always place the radio in a Motorola-approved clip, holder, holster, case,

or body harness for this product. Using approved body-worn accessories is important because the

use of non-Motorola-approved accessories may result in exposure levels, which exceed the IEEE/

ICNIRP occupational/controlled environment RF exposure limits.

●If you are not using a body-worn accessory and are not using the radio in the intended use position,

along side the head in the phone mode (TETRA only), in front of the face in the hand held mode,

then ensure the antenna and the radio are kept 2.5 cm (one inch) from the body when transmitting.

Keeping the radio at a proper distance is important because RF exposures decrease with

increasing distance from the antenna.

v

Hand-held Mode - Operating Instructions

●Hold the radio in a vertical position in front of the face with the microphone (and other

parts of the radio including the antenna) at least 2.5 cm (one inch) away from the nose or

lips. Antenna should be kept away from the eye. Keeping the radio at a proper distance is

important since RF exposures decrease with increasing distance from the antenna.

Phone Mode (TETRA only) - Operating Instructions

●When placing or receiving a phone call, hold your radio product as you would a wireless telephone.

Speak directly into the microphone.

Approved Accessories

●Use only Motorola-approved supplied or replacement antennas, batteries, and accessories. Use of

non–

Motorola - approved antennas, batteries and accessories may exceed IEEE/ICNIRP RF exposure

guidelines.

For a list of Motorola-approved antennas, batteries, and other accessories please see your dealer

or local Motorola contact. Your nearest dealer can be found at the following web site:

http://www.motorola.com/cgiss/emea/dealerlocator.html

ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY

NOTE: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if

inadequately shielded, designed or otherwise configured for electromagnetic compatibility.

Facilities

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.

Aircraft

When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in

accordance with applicable regulations per airline crew instructions.

Medical Devices

Pacemakers

The Advanced Medical Technology Association (AdvaMed) recommends that a minimum separation

of 15 cms (6 inches) be maintained between a handheld wireless radio and a pacemaker.These

recommendations are consistent with those of the U.S. Food and Drug Administration.

Persons with pacemakers should:

●ALWAYS keep the radio more than 15 cms from their pacemaker when the radio is turned ON.

●Not carry the radio in the breast pocket.

●Use the ear opposite the pacemaker to minimize the potential for interference.

●Turn the radio OFF immediately if you have any reason to suspect that interference is taking place.

Hearing Aids

Some digital wireless radios may interfere with some hearing aids. In the event of such interference,

you may want to consult your hearing aid manufacturer to discuss alternatives.

Other Medical Devices

If you use any other personal medical device, consult the manufacturer of your device to determine if

it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this

information.

Use of Communication Devices While Driving

Always check the laws and regulations on the use of radios in the areas where you drive.

●Give full attention to driving and to the road.

●Use hands-free operation, if available.

●Pull off the road and park before making or answering a call, if driving conditions or regulations so

require.

OPERATIONAL WARNINGS

Vehicles with an air bag

Refer to vehicle manufacturer's manual prior to installation of electronic equipment to avoid

interference with air bag wiring.

Potentially explosive atmospheres

Blasting caps and areas

OPERATIONAL CAUTIONS

Antennas

Batteries

WARNING: Do not place a portable radio in the area over an air bag or in the air bag

deployment area. Air bags inflate with great force. If a portable radio is placed in the air bag

deployment area and the air bag inflates, the radio may be propelled with great force and

cause serious injury to occupants of the vehicle.

WARNING: Turn off your radio prior to entering any area with a potentially explosive

atmosphere, unless it is a radio type especially qualified for use in such areas as

"Intrinsically Safe" (for example, Factory Mutual, CSA, UL, CENELEC or ATEX Approved). Do

not remove, install, or charge batteries in such areas. Sparks in a potentially explosive

atmosphere can cause an explosion or fire resulting in bodily injury or even death.

NOTE The areas with potentially explosive atmospheres referred to above include fuelling areas such as

below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains

chemicals or particles, such as grain, dust or metal powders. Areas with potentially explosive

atmospheres are often but not always posted.

WARNING: To avoid possible interference with blasting operations, turn off your radio when

you are near electrical blasting caps, in a blasting area, or in areas posted:

"Turn off two-way radio". Obey all signs and instructions.

CAUTION: Do not use any portable radio that has a damaged antenna. If a damaged antenna

comes into contact with your skin, a minor burn can result.

CAUTION: All batteries can cause property damage and/or bodily injury such as burns if a

conductive material such as jewellery, keys, or beaded chains touch exposed terminals. The

conductive material may complete an electrical circuit (short circuit) and become quite hot.

Exercise care in handling any charged battery, particularly when placing it inside a pocket,

purse, or other container with metal objects.

INTRINSICALLY SAFE RADIO INFORMATION

The Intrinsically safe approval unit refers to a product that has been approved as intrinsically safe by

an approval agency (for example FM Approvals, CSA, UL, CENELEC or ATEX) and certifies that a

particular product meets the Agency's applicable intrinsic safety standards for specific types of

hazardous classified locations. A portable radio that has been approved for intrinsic safety will have

Approval label attached to the radio to identify the unit as being Approved for specified hazardous

atmospheres. This label specifies the hazardous Class/Division/Group along with the part number of

the battery that must be used. The Intrinsically Safe Approval Label will be located on the portable

radio unit.

Operational Cautions for Intrinsic Safe Equipment

Warnings for Radios Approved as Intrinsically Safe

Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability

and the intrinsic safety approval labelling (FM, UL, CSA, CENELEC or ATEX). Radios will not be

upgraded to this capability and labeled once they have been shipped to the field.

A modification changes the unit’s hardware from its original design configuration. Modifications can

only be made by the original product manufacturer.

●Do not operate radio communications equipment in a hazardous atmosphere unless it is a

type especially qualified (for example, FM, UL, CSA, or CENELEC or ATEX approved). An

explosion or fire may result.

●Do not operate a radio unit that has been approved as intrinsically safe product in a

hazardous atmosphere if it has been physically damaged (for example, 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 changeaccessories in a hazardous atmosphere. Contact sparking

may occur while installing or removing accessories and cause an explosion or fire.

●Turn the radio off before removing or installing a battery or accessory.

●Do not disassemble an intrinsically safe product in any way that exposes the

internal circuits of the unit.

●Failure to use an intrinsically safe approved battery or Approved accessories

specifically approved for the radio unit may result in the dangerously unsafe

condition of an unapproved radio combination being used in a hazardous location.

●Unauthorized or incorrect modification of the intrinsically safe approved Product

will negate the approval rating of the product.

●Incorrect repair or relabeling of any intrinsically safe Agency-approved radio 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.

ix

Repair

A repair constitutes something done internally to the unit that would bring it back to its original

condition.

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.

Do Not Substitute Options or Accessories

The Motorola communications equipment certified as intrinsically safe by the approving agency, (FM,

UL, CSA, CENELEC or ATEX) is tested as a complete system which consists of the listed agency

Approved portable, Approved battery, and Approved accessories or options, or both. This 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 by the Approving Agency (FM, UL, CSA,

CENELEC or ATEX).

The Intrinsically Safe Approval Label affixed to radio refers to the intrinsically safe classification of that

radio product, and the approved batteries that can be used with that system.

The manual PN referenced on the Intrinsically Safe Approval Label identifies the approved

Accessories and or options that can be used with that portable radio unit.

Using a non Motorola intrinsically safe battery and or accessory with the Motorola approved radio unit

will void the intrinsically safe approval of that radio unit.

REPAIRS FOR MOTOROLA PRODUCTS WITH INTRINSICALLY SAFE APPROVAL ARE

THE RESPONSIBILITY OF THE USER.

●Repairs to a Motorola FM approved radio product should only be done at a location

that has been FM audited under the FM 3605 repairs and service standard.

●Contact Motorola for assistance regarding repairs and service of Motorola

intrinsically safe equipment.

INTRINSICALLY SAFE RADIO INFORMATION

1.0 FMRC Approved Equipment

Anyone intending to use a radio in a location where hazardous concentrations of flammable material

exist (hazardous atmosphere) is advised to become familiar with the subject of intrinsic safety and

with the National Electric Code NFPA 70 (National Fire Protection Association) Article 500

(hazardous [classified] locations).

An Approval Guide, issued by Factory Mutual Research Corporation (FMRC), lists manufacturers

and the products approved by FMRC for use in such locations. FMRC has also issued a voluntary

approval standard for repair service (“Class Number 3605”).

FMRC Approval labels are attached to the radio to identify the unit as being FM

Approved for specified hazardous atmospheres. This label specifies the hazardous

Class/Division/Group along with the part number of the battery that must be used.

Depending on the design of the portable unit, this FM label can be found on the

back of the radio housing or the bottom of the radio housing.Their Approval mark is shown above.

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 done by the original product manufacturer at one of its FMRC audited manufacturing

facilities.

Unauthorized or incorrect modification of an FMRC Approved Product unit will negate the Approval

rating of the product.

WARNING: Do not operate radio communications equipment in a hazardous atmosphere

unless it is a type especially qualified (e.g. FMRC Approved) for such use. An explosion or

fire may result.

WARNING: Do not operate the FMRC Approved Product in a hazardous atmosphere if it has

been physically damaged (e.g. cracked housing). An explosion or fire may result.

WARNING: 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.

WARNING: 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.

WARNING: Do not operate the FMRC Approved Product unit in a hazardous location with the

accessory contacts exposed. Keep the connector cover in place when accessories are not

used.

WARNING: Turn radio off before removing or installing a battery or accessory.

WARNING: Do not disassemble the FMRC Approved Product unit in any way that exposes

the internal electrical circuits of the unit.

WARNING: 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.

2-2 INTRINSICALLY SAFE RADIO INFORMATION

2.0 Repair of FMRC Approved Products

REPAIRS FOR MOTOROLA FMRC APPROVED PRODUCTS 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.

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:

2.1 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.

2.2 Relabelling

The repair facility shall have a method by which the replacement of FMRC Approval labels are

controlled to ensure that any relabelling 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

providing satisfactory evidence that the unit being relabelled 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.

WARNING: Incorrect repair or relabelling of any FMRC Approved Product unit could

adversely affect the Approval rating of the unit.

WARNING: Use of a radio that is not intrinsically safe in a hazardous atmosphere could

result in serious injury or death.

2.3 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 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 with

FM Approved radio and battery combination from the manufacturer. The Approval guide, or the

Approval standard Class Number 3605 document for repairs and service, can be ordered directly

through Factory Mutual Research Corporation located in Norwood, Massachusetts.

Chapter 3

MAINTENANCE

1.0 Introduction

This chapter provides details about the following:

❏Preventive maintenance (inspection and cleaning)

❏Safe handling of CMOS and LDMOS devices

❏Disassembly and reassembly of the radio

❏Repair procedures and techniques

❥Installation of Option Boards

2.0 Preventive Maintenance

The radios do not require a scheduled preventive maintenance program; however, periodic visual

inspection and cleaning is recommended.

2.1 Inspection

Check that the external surfaces of the radio are clean, and that all external controls and switches

are functional. It is not recommended to inspect the interior electronic circuitry.

2.2 Cleaning Procedures

The following procedures describe the recommended cleaning agents and the methods to be used

when cleaning the external and internal surfaces of the radio. External surfaces include the front

cover, housing assembly and battery case. These surfaces should be cleaned whenever a periodic

visual inspection reveals the presence of smudges, grease, and/or grime.

The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild

dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit

boards and their components is isopropyl alcohol (70% by volume).

Cleaning External Plastic Surfaces

Apply the 0.5% detergent-water solution sparingly with a stiff, non-metallic, short-bristled brush to

work all loose dirt away from the radio. Use a soft, absorbent, lintless cloth or tissue to remove the

solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks,

or crevices.

NOTE The Servicing of your Intrinsically Safe Radios

In order to maintain compliance, radios that are FM Approved to intrinsically safe standards

MUST be repaired at FM audited service centers. See Paragraph 2.5 (Technical Support)

on page 1-3 for more information.

NOTE Internal surfaces should be cleaned only when the radio is disassembled for service or

repair.

CAUTION: The effects of certain chemicals and their vapors can have harmful results on

certain plastics. Avoid using aerosol sprays, tuner cleaners, and other chemicals.

!

3-2 MAINTENANCE

Cleaning Internal Circuit Boards and Components

Isopropyl alcohol (70%) may be applied with a stiff, non-metallic, short-bristled brush to dislodge

embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the

dislodged material out and away from the inside of the radio. Make sure that controls or tunable

components are not soaked with alcohol. Do not use high-pressure air to hasten the drying process

since this could cause the liquid to collect in unwanted places. After completing of the cleaning

process, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl

alcohol to the frame, front cover, or back cover.

3.0 Safe Handling of CMOS and LDMOS Devices

Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios, and

are susceptible to damage by electrostatic or high voltage charges. Damage can be latent, resulting

in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent

device damage during disassembly, troubleshooting, and repair.

Handling precautions are mandatory for CMOS circuits and are especially important in low humidity

conditions. DO NOT attempt to disassemble the radio without first referring to the following

CAUTION statement.

NOTE Always use a fresh supply of alcohol and a clean container to prevent contamination by

dissolved material (from previous usage).

CAUTION: This radio contains static-sensitive devices. Do not open the radio unless you are

properly grounded. Take the following precautions when working on this unit:

❏Store and transport all CMOS devices in conductive material so that all exposed

leads are shorted together. Do not insert CMOS devices into conventional plastic

“snow” trays used for storage and transportation of other semiconductor devices.

❏Ground the working surface of the service bench to protect the CMOS device. We

recommend using the Motorola Static Protection Assembly (part number

0180386A82), which includes a wrist strap, two ground cords, a table mat, and a

floor mat.

❏Wear a conductive wrist strap in series with a 100k resistor to ground. (Replacement

wrist straps that connect to the bench top covering are Motorola part number

RSX4015.)

❏Do not wear nylon clothing while handling CMOS devices.

❏Do not insert or remove CMOS devices with power applied. Check all power

supplies used for testing CMOS devices to be certain that there are no voltage

transients present.

❏When straightening CMOS pins, provide ground straps for the apparatus used.

❏When soldering, use a grounded soldering iron.

❏If at all possible, handle CMOS devices by the package and not by the leads. Prior

to touching the unit, touch an electrical ground to remove any static charge that you

may have accumulated. The package and substrate may be electrically common. If

so, the reaction of a discharge to the case would cause the same damage as

touching the leads.

!

Repair Procedures and Techniques — General 3-3

4.0 Repair Procedures and Techniques — General

Parts Replacement and Substitution

When damaged parts are replaced, identical parts should be used. If the identical replacement part

is not locally available, check the parts list for the proper Motorola part number and order the part

from the nearest Motorola Communications parts centre listed in the “Piece Parts” section of this

manual.

Rigid Circuit Boards

This family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not

accessible, some special considerations are required when soldering and unsoldering components.

The printed-through holes may interconnect multiple layers of the printed circuit. Therefore, exercise

care to avoid pulling the plated circuit out of the hole.

When soldering near the 20-pin and 40-pin connectors:

❏Avoid accidentally getting solder in the connector.

❏Be careful not to form solder bridges between the connector pins.

❏Examine your work closely for shorts due to solder bridges.

Flexible Circuits

The flexible circuits are made from a different material than the rigid boards, and require different

soldering techniques. Excessive prolonged heat on a flexible circuit can damage the material.

Therefore, avoid excessive heat and excessive bending.

For parts replacement, use the ST-1087 Temperature-Controlled Solder Station with a 600-700

degree tip, and use small diameter solder such as ST-633. The smaller size solder will melt faster

and require less heat to be applied to the circuit.

To replace a component on a flexible circuit:

1. Grasp with seizers (hemostats) the edge of the flexible circuit near the part to be removed.

NOTE Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit

boards) were developed and assembled using environmentally preferred components

and solder assembly techniques to comply with the European Union’s ROHS and WEEE

directives (Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC

and Restriction of Hazardous Subtances (ROHS) Directive 2002/95/EC). To maintain

product compliance and reliability, use only the Motorola specified parts in this manual.

For the identification of lead (Pb) free assemblies, all EPP products will carry the EPP

Marking, shown below, on the printed circuit board (PCB). This marking provides infor-

mation to those performing assembly, servicing and recycling operation on this product,

adhering to the JEDEC standard #97. The EPP Marking takes the form of a label or

marking on the PCB.

3-4 MAINTENANCE

2. Pull gently.

3. Apply the tip of the soldering iron to the component connections while pulling with the seizers.

5.0 Disassembling and Reassembling the Radio — General

Since these radios may be disassembled and reassembled with the use of only four (board to

casting) screws, it is important to pay particular attention to the snaps and tabs, and how parts align

with each other.

The following tools are required for disassembling the radio:

❏Small flat blade screwdriver

❏penknife-size screwdriver

❏TORX™ T6 screwdriver

❏Chassis opener (6680702Z01)

If a unit requires more complete testing or service than is customarily performed at the basic level,

send this unit to a Motorola Authorized Service Centre. (See Chapter 1 for a list of authorized

service centres.)

The following disassembly procedures should be performed only if necessary:

Chassis Assembly Disassembly (Paragraph 6.2)

Keypad, Display, and Keypad/Option Board Disassembly (Paragraph 6.3)

Speaker, Microphone, and Universal Connector Flex Disassembly (Paragraph 6.4)

PTT Disassembly (Paragraph 6.5)

Control Top Disassembly (Paragraph 6.7)

6.0 Radio Disassembly — Detailed

POWER UP SELF-TEST

1.0 Error Codes

Turning on the radio starts a self-test routine that checks the radio functionality. If the checks are

successful, the radio generates a high-pitched self-test pass tone. If the self-test is not successful,

one low-pitched (300Hz) error tone is heard and the RED LED flashes several times to indicate the

reason for the failure (see Table 7-1 below). After flashing the error code, the LED remains off for 5

seconds and then repeats the error code. The LED sequence and the error tone continue until the

radio is switched off. Radios with displays are also able to display error codes. The meaning of the

LED indication, the displayed error codes and the related corrections are listed in Table 7-1.
