SAFETY

Product Safety and RF Exposure for Portable Two-Way Radios

THIS CHAPTER IS AN EXTRACT OF THE MULTI LINGUAL PORTABLE SAFETY

BOOKLET PUBLICATION No. 6864117B25. FOR THE LATEST SAFETY

INFORMATION REFER TO THE SEPARATE SAFETY BOOKLET DELIVERED WITH

YOUR RADIO.

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/ICNIRP and International standards. This

radio device is NOT authorized for general population consumer 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

BEFORE USING THIS RADIO, READ THIS BOOKLET WHICH CONTAINS IMPORTANT OPERATING

INSTRUCTIONS FOR SAFE USAGE AND RF ENERGY AWARENESS AND CONTROL INFORMATION AND

OPERATIONAL INSTRUCTIONS FOR COMPLIANCE WITH RF ENERGY EXPOSURE LIMITS IN

APPLICABLE NATIONAL AND INTERNATIONAL STANDARDS. ALSO READ THE OPERATIONAL

INSTRUCTIONS FOR SAFE USAGE. FOR RADIOS THAT HAVE BEEN APPROVED AS INTRINSICALLY

SAFE, READ THE INSTRUCTIONS AND INFORMATION ON INTRINSIC SAFETY ON PAGE VII.

vi MTH800 TETRA Handportable Terminal / Basic Service Manual SAFETY

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.

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 the portable 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"

SAFETY MTH800 TETRA Handportable Terminal / Basic Service Manual vii

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:

• 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.

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:

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 centimeters (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 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 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.

SAFETY MTH800 TETRA Handportable Terminal / Basic Service Manual ix

Use of Communication Devices While Driving

Always check the laws and regulations on the use of radios in the area 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

Operational Cautions

For Vehicles With An Air Bag

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

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.

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.

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.

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 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.

xMTH800 TETRA Handportable Terminal / Basic Service Manual SAFETY

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

Operational Cautions for Intrinsic Safe Equipment

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 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.

SAFETY MTH800 TETRA Handportable Terminal / Basic Service Manual xi

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.

Digital Modulation Technology MTH800 TETRA Handportable Terminal / Basic Service Manual 3 - 1

CHAPTER 3

OVERVIEW

To achieve a high spectrum efficiency, the MTH800 uses digital modulation

technology and sophisticated voice-compression algorithm. The voice of the

person speaking into the microphone is converted into a digital bit stream

consisting of zeros (0) and ones (1). This stream is then modulated into a radio-

frequency (RF) signal, which is transmitted over the air to another terminal. The

process is called digital modulation.

Digital Modulation Technology

The MTH800 is a 380-430 or 440-470MHz TETRA Handportable Terminal that

can operate in dispatch and phone modes. The terminal can also operate in TMO

(Trunked Mode Operation) and DMO (Direct Mode Operation) modes. It uses two

digital technologies: π/4 DQPSK and Time Division Multiple Access (TDMA).

π/4 DQPSK is a modulation technique that transmits information by altering the

phase of the radio frequency (RF) signal. Data is converted into complex

symbols, which alter the RF signal and transmit the information. When the signal

is received, the change in phase is converted back into symbols and then into the

original data.

The system can accommodate 4-voice channels in the standard 25 kHz channel

as used in the two-way terminal.

Time Division Multiple Access (TDMA) is used to allocate portions of the RF

signal by dividing time into four slots, one for each unit.

Time allocation enables each unit to transmit its voice information without

interference from other transmitting units. Transmission from a unit or base

station is accommodated in time-slot lengths of 15 milliseconds and frame

lengths of 60 milliseconds. The TDMA technique requires sophisticated

algorithms and a digital signal processor (DSP) to perform voice

compressions/decompressions and RF modulation/demodulation.

Voice Compression Technology

Voice is converted into a digital bit stream by sampling the voice at a high rate

and converting the samples into numbers, which are represented by bits.

Voice compression reduces the number of bits per second while maintaining the

voice at an acceptable quality level. The MTH800 uses a coding technique called

ACELP (Algebraic Code Excited Linear Prediction). The compressed voice-data

bits modulate the RF signal.

3 - 2 MTH800 TETRA Handportable Terminal / Basic Service Manual Description

Description

Transceiver Description

All the terminal circuitry is contained in the Digital/RF Board and the keypad

board. The Digital/RF board is divided into the following sections: digital,

frequency generating, transmitter, and receiver.

Digital Section Description

The digital section includes the Patriot IC that consists of the Mcore risk machine

and the Digital Signal Processor (DSP).

The Mcore is the controller of the Digital/RF Board. It controls the operation of the

transmitter, receiver, audio, and synthesizer integrated circuits located in the RF

section. It communicates with the keypad and display.

The Digital Signal Processor (DSP) performs modulation and de-modulation

functions for the terminal. It also performs Forward Error Correction and other

correction algorithms for overcoming channel errors and ACELP speech coding.

It carries out linear 10-bit analog to digital conversions, audio filtering, and level

amplification for the microphone audio input and the received audio output.

The power and audio section is based on the GCAP III and includes power

supplies, 13-bit CODEC, audio routing, microphone and ear piece amplifiers. A

audio power amplifier is used for the loud speaker.

Transmitter Path Description

The transmitter circuitry includes a linear class AB Power Amplifier (PA) for the

linear modulation of the MTH800. It includes a cartesian feedback loop to

enhance its transmitter linearity and reduced splattering power into adjacent

channels.

The transmitter path consists of a cartesian feedback loop that contains the

forward and loop feedback paths.

The forward path includes the JAVELIN IC, BALUN, Attenuator, Power Amplifier

and Isolator.

The loop feedback path includes the directional coupler, attenuator, BALUN, and

JAVELIN IC.

Description MTH800 TETRA Handportable Terminal / Basic Service Manual 3 - 3

The cartesian Feedback output power passes to the antenna through the

Isolator, Antenna Switch, Harmonic Filter and Duplexer.

Receiver Path Description

The receiver section in MTH800 is based on the novel DCR (Direct Conversion)

technology, the main concept of this technology is down converting of the RF

signal directly into a base band signal, skipping the intermediate stage of IF

signal.

The receiver path includes the Antenna Switch, Limiter, 10dB Step Attenuator,

Tunable Filter, LNA integrated with 28dB Step Attenuator and 40dB of AGC

continuous attenuation, Pre-selector Band Pass Filter, Balun, Half-Life Mixer, 1-

CHAPTER 6

MAINTENANCE

Preventive Maintenance

This TETRA Handportable Terminal does not require a scheduled preventive

maintenance program. However, periodic visual inspection is recommended.

Inspection

Inspect the terminal’s external surfaces. A detailed inspection of interior circuitry

is not needed or recommended.

Cleaning

The following procedures describe the recommended cleaning agents and

methods to be used when cleaning the external and internal surfaces of the

radio. External surfaces should be cleaned whenever a periodic visual inspection

reveals the presence of smudges, compound, or grime. Internal surfaces (circuit

boards and components) should be cleaned only when the radio is disassembled

for servicing or repair.

The only recommended agent for cleaning external radio surfaces is a 0.5%

solution (one teaspoon of detergent per gallon of water) of mild dishwashing

detergent in water. The internal surfaces should be cleaned only with isopropyl

alcohol (100% by volume).

NOTE: Internal surfaces should be cleaned only when the radio is disassembled

for service or repair.

Take care to clean the bottom connector frequently and particularly prior

to the programming procedure e.g. with a soft brush (do not use fluids).

The effects of certain chemicals and their

vapors can have harmful results on certain

plastics. Avoid using aerosol sprays, tuner

cleaners, and other chemicals.

6 - 2 MTH800 TETRA Handportable Terminal / Basic Service Manual MAINTENANCE

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.

Cleaning Internal Circuit Boards and Components

Isopropyl alcohol (100%) 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.

Safe Handling of CMOS Devices

Complementary metal-oxide semiconductor (CMOS) devices are used in the

terminal. While the attributes of CMOS devices are many, their characteristics

make them susceptible to damage by electrostatic or high voltage charges.

Damage can be latent, resulting in failure occurring weeks or months later.

Therefore, special precautions must be taken to prevent device damage during

disassembly, troubleshooting, and repair. The following handling precautions are

mandatory for CMOS circuits, and are especially important in low humidity

conditions.

•All CMOS devices must be stored or transported in conductive material so that

all exposed leads are shorted together. CMOS devices must not be inserted

into conventional plastic “snow” or plastic trays of the type that are used for

storage or transportation of other semiconductor devices.

•All CMOS devices must be placed on a grounded bench surface and the

technician must also be grounded before handling the devices. This is done

most effectively by having the technician wear a conductive wrist strap in

series with a 100kW resistor to ground.

•Do not wear nylon clothing while handling CMOS circuits.

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

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

voltage transients present.

•When straightening CMOS device leads, provide ground straps for the

apparatus used.

•When soldering, use a grounded soldering iron.

•All power must be turned off in a system before printed circuit boards

containing CMOS devices are inserted, removed, or soldered.

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

contamination by dissolved material (from previous usage).

MAINTENANCE MTH800 TETRA Handportable Terminal / Basic Service Manual 6 - 3

Pre-baking of Integrated Circuits

Electronic components are generally coated with plastic material which has the

nature of not being waterproof. If kept unsealed, the components can absorb

humidity. When soldered to the board (especially with reflow techniques), the

sudden change in temperature can cause fissure or crack which can result in

malfunction or damage.

To avoid this problem, these moisture sensitive components (MS) should be

stored and shipped in a sealed wrapping (dry pack). Processing is not required

only with “dry components” when an uninterrupted dry storage can be

guaranteed, otherwise the components have to be pre-baked.

If a reflow procedure takes place close to MS components, the whole board

must be pre-baked.

Refer to the table below.

Baking Precautions for TETRA Power Amplifiers (PAs)

PAs in an open reel after baking should be used within 168 hours. After 168

hours the PAs must not be used until baked again. Because this is quite a short time,

use at least two reels for each build: one on the machine, and the other still in baking.

After 168 hours the reel on the machine should be replaced with the freshly baked

reel. It is recommended to order a sufficient reserve of PAs, so that at least two reels

will be available in each build.

In addition, please note the following very important precautions that must be

observed when baking TETRA PAs before builds:
