RF Energy Exposure Awareness and Control Information and Operational Instructions for Occupational Use
NOTICE: This radio is intended for use in occupational/controlled conditions where users
have full knowledge of their exposure and can exercise control over their exposure to meet the occupational limits in FCC and International standards. This radio device is NOT authorized for general population or consumer use.
-
iii
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
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.
Page 6
iv
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. 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.
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 FCC 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 factor (5% talk-
5% listen-90% standby) even though this radio complies with FCC occupational exposure limits and may operate at duty 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; 47CFR 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" "Additional Requirements for SMR, Cellular and PCS Product Certification"
RF Exposure Compliance and Control Guidelines and Operating Instructions
To control your exposure and ensure compliance with the occupational/controlled environment exposure limits, always adhere to the following procedures.
Guidelines:
Do not remove the RF Exposure Label from the device.
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.
Page 7
Operating Instructions
Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push­To-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).
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 one inch (2.5 centimeters) 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.
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 FCC 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 in front of the face, ensure the antenna and the radio are kept at least one inch (2.5 centime­ters) from the body when transmitting. Keeping the radio at a proper distance is important because RF exposures decrease with increasing distance from the antenna.
Approved Accessories
Use only Motorola-approved supplied or replacement antennas, batteries, and accessories. Use of Non-Motorola approved antennas, batteries, and accessories may exceed the FCC (IEEE) and ICNIRP RF exposure guidelines.
For a list of Motorola-approved accessories, visit the following website, which lists approved accessories for your radio model: http://www.motorola.com/governmentandenterprise.

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 6 inches (15 centimeters) be maintained between a handheld wireless radio and a pacemaker. These recommendations are consistent with those of the U.S. Food and Drug Administration.
Page 8
vi
Persons with pacemakers should:
ALWAYS keep the radio more than 6 inches (15 centimeters) 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 there is 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
For vehicle with air bags Refer to vehicle manufacturer's manual prior to installation of electronic equipment to avoid
interference with air bag wiring. 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.
Potentially Explosive Atmospheres (Explosive atmospheres refers to hazard classified locations that may contain hazardous
gas, vapors, or dusts.) Turn off your radio prior to entering any area with a potentially explosive atmosphere unless
it is a portable radio type especially qualified for use in such areas as Intrinsically Safe (for example, Factory Mutual, CSA, UL, or CENELEC).
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.
The areas with potentially explosive atmospheres referred to above include fueling areas such as below decks on boats, fuel or chemical transfer or storage facilities, and 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.
Blasting Caps And Blasting Areas 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.
Page 9
Operational Cautions
Antennas
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.
Batteries
All batteries can cause property damage and/or bodily injury, such as burns, if a conductive material such as jewelry, keys, or beaded chains touches 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, or Cenelec) 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.
vii
Operational Cautions for Intrinsic Safe Equipment
• Do not operate radio communications equipment in a hazardous atmosphere unless it is a type especially qualified (for example, FM, UL, CSA, or CENELEC 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.
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). Radios will not be upgraded to this capability and labeled once they have been shipped to the field.
Page 10
viii
Repair
A modification changes the unit's hardware from its original design configuration. Modifications can only be made by the original product manufacturer.
• 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.
• 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.
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.
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 that 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) 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).
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.

Section 2 MAINTENANCE

1.0 Introduction

This chapter provides details about the following:
Preventive Maintenance
Safe Handling of CMOS and LDMOS Devices
General Repair Procedures and Techniques
Disassembling and Reassembling the Radio

2.0 Preventive Maintenance

Periodic visual inspection and cleaning is recommended.
2-1

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.
NOTE
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).
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.
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.
Page 18
2-2 Safe Handling of CMOS and LDMOS Devices
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.
NOTE
Always use a fresh supply of alcohol and a clean container to prevent contamination by dissolved material (from previous usage).

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.
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

Repair Procedures and Techniques — General 2-3
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 center listed in the 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.
Piece Parts section of this
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 F 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.
2. Pull gently.
3. Apply the tip of the soldering iron to the component connections while pulling with the seizers.
NOTE
Do not attempt to puddle-out components. Prolonged application of heat may damage the flexible circuit.
Chip Components
Use either the RLN-4062 Hot-Air Repair Station or the Motorola 0180381B45 Repair Station for chip component replacement. When using the 0180381B45 Repair Station, select the TJ-65 mini­thermojet hand piece. On either unit, adjust the temperature control to 700 degrees F. (370 degrees C), and adjust the airflow to a minimum setting. Airflow can vary due to component density.
To remove a chip component, select a hot-air hand piece and position the nozzle of the hand
piece approximately 1/8” above the component to be removed. Begin applying the hot air. Once the solder reflows, remove the component using a pair of tweezers. Using solder wick and a soldering iron or a power desoldering station, remove the excess solder from the pads.
Page 20
2-4 Disassembling and Reassembling the Radio — General
To replace a chip component using a soldering iron, select the appropriate micro-tipped
soldering iron and apply fresh solder to one of the solder pads. Using a pair of tweezers, position the new chip component in place while heating the fresh solder. Once solder wicks onto the new component, remove the heat from the solder. Heat the remaining pad with the soldering iron and apply solder until it wicks to the component. If necessary, touch up the first side. All solder joints should be smooth and shiny.
To replace a chip component using hot air, select the hot-air hand piece and reflow the solder
on the solder pads to smooth it. Apply a drop of solder paste flux to each pad. using a pair of tweezers, position the new component in place. Position the hot-air hand piece approximately 1/8” above the component and begin applying heat. Once the solder wicks to the component, remove the heat and inspect the repair. All joints should be smooth and shiny.
5.0 Disassembling and Reassembling the Radio — General
For disassembly or reassembly of the radio, it is important to pay particular attention to all the snaps and tabs, and how parts align with each other.
The following tools are required for disassembling the radio:
Phillips screwdriver
Flat head screwdriver
Chassis Opener
Crab Eye Nut Opener
Tweezers
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 Center.

2.0 Programming Your Radio

2.1 Overview of the Programming Process

To prepare properly programmed radios for your customers, you should
1. program your radio with all the necessary parameters, as required by your customers, and
then
2. clone these parameters over to all your customer’s radios.

2.2 Cloning Radio Parameters to User Radios

Cloning duplicates the contents of Radio 1 (master radio) into Radio 2 (slave radio).

2.3 Parameters which are cloned

Radio Configuration parameters
Conventional Personality parameters

2.4 Parameters which are not cloned

Unit Serial Number.
Model Number

2.5 To Clone a Radio

Busy Channel Lockout (BCLO)
Carrier An electromagnetic signal that is transmitted on a selected frequency for the
CD Compact Disk.
Channel A single path separated by frequency or time divisions used for transmitting
Codeplug A solid-state chip inside a radio where the radio’s personality data is stored.
CPS Acronym for Customer Programming Software. Licensed Motorola software
Frequency (a) The location of the center of a channel of operation in the radio spectrum.
Model Number The model number identifies the type of radio. This information is stored in the
Normal Scan For Normal Scan, the radio assigns equal priority to all members in the Scan
If BCLO is activated, the radio will check for channel activity before transmit­ting. If activity is detected, transmission is prohibited. For carrier squelch mode, radio will not transmit, if it is receiving carrier. For coded squelch mode, it will not transmit, if it is receiving carrier with different PL/DPL code.
purpose of carrying voice or data transmissions along with it. Carrier can then be received by all radios listening on that frequency.

radio’s codeplug.
List selected for the current channel. When the radio is scanning a Scan List (Active Scan), all scan list members (including the Home Channel) will be allo cated equal time to be scanned. For example, if the Home Channel is H1, and the Scan List Members are Nn, then the scanning sequence is: N1, N2, N3, ..., H1, N1, N2, ..., etc.
-
PLL Phase-Locked Loop: a circuit in which an oscillator is kept in phase with a ref-
erence, usually after passing through a frequency divider.
Priority Scan For Priority Scan, the radio assigns the highest priority to the channel defined
in the CPS as Priority Channel. When the radio is scanning a Scan List (Active Scan), 50% of the scans are targeted at the Priority Channel. For example, if the Priority Channel is P1, and the non-priority Scan List Members are Nn, then the scanning sequence is: P1, N1, P1, N2, P1, N3, P1, N4, P1, N5, etc.
Program The transfer of CPS information from the computer’s temporary memory (RAM)
to the radio.
PTT Push-To-Talk: the switch located on the left side of the radio which, when
pressed, causes the radio to transmit.
RESET Reset line: an input to the microcontroller that restarts execution.
Reverse Burst / Turn Off Code
Causes a Tone Private Line (TPL) or Digital Private Line (DPL) code to be transmitted at the end of a transmission - once PTT is released, and while op erating on the current channel. This sub-audible tone causes the receiving ra­dio to mute its speaker before loss of a carrier is detected. Muting the speaker eliminates unwanted noise (squelch tail) during loss of carrier detection.

Scan List The Scan List determines which channels the radio scans, when operating in
the Scan Mode, on the current channel.
Scan List Member The Scan List allows you to select the grouping of channels that make up the
current Scan List Member channels. This grouping of Scan List Member chan nels can then be scanned for transmission activity - one at a time, when the ra­dio is in Scan Mode. A Scan List can have a maximum of 16 Scan List Members. Scan List Member scanning priority is definable.
Scan Mode When the radio is in one of the two Scan States: Active Scan and Landed Scan.
This mode is initiated when the programmable SCAN button is pressed.
Serial Number Each radio has its own unique serial number. This information is stored in the
radio’s codeplug.
Software Computer programs, procedures, rules, documentation, and data pertaining to
the operation of a system.
Squelch Muting of audio circuits when received signal levels fall below a pre-determined
value.

Tone Private Line (TPL)
Tx Frequency A designated frequency used when transmitting carrier for the current channel.
µC Microcontroller.
UHF Ultra High Frequency.
VHF Very High Frequency.
Transmitted when the receiving radio is to only receive calls from radios with specific TPL codes, this creates communications groups while operating in Conventional Dispatch mode. TPL allows for more use and privacy on a fre quency. TPL is transmitted at a sub-audible (not able to be heard) frequency. Also known as CTCSS.
