BOOKLET PUBLICATION No. 6866537D37_.

!

C a u t i o n

FOR THE LATEST SAFETY INFORMATION REFER TO THE SEPARATE SAFETY
BOOKLET DELIVERED WITH YOUR TERMINAL.

BEFORE USING THIS TERMINAL READ THIS INFORMATION WHICH
CONTAINS IMPORTANT OPERATING INSTRUCTIONS FOR SAFE USAGE AND
RF ENERGY AWARENESS AND CONTROL INFORMATION FOR COMPLIANCE
WITH RF ENERGY EXPOSURE LIMITS IN APPLICABLE NATIONAL AND
INTERNATIONAL STANDARDS.

RF Energy Exposure Awareness and Control Information, and Operational Instructions for FCC Occupational Use Requirements.

Note: This terminal 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 FCC/ICNIRP lim­its. This terminal device is NOT authorized for general population, consumer or any other use.

This 2-way terminal 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 organisations 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 2-way terminals 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 2-way terminals. 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 Web sites for more information on what RF energy exposure is and how
to control your exposure to assure compliance with established RF exposure limits.

viii CM5000 Mobile Repeater/Gateway - Basic Service Manual Product Safety and RF Exposure

Federal Communications Commission Regulations (US markets only)

The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for mobile
2-way terminals before they can be marketed in the U.S. When 2-way terminals 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
label directing users to specific user awareness information. Your Motorola 2-way terminal has an
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 Standard

Your Motorola terminal is designed and tested to comply with a number of national and international
standards and guidelines (listed below) regarding human exposure to radio frequency
electromagnetic energy. This terminal complies with IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environments at duty factors of up to 50% talk–50% listen
and is authorised by the IEEE/ICNIRP for occupational use. In terms of measuring RF energy for
compliance with these exposure guidelines, your terminal antenna radiates measurable RF energy
only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode.

Your Motorola two-way terminal 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, Brasil Regulatory Authority, Resolution 256 (April 11, 2001) “additional requirements
for SMR, cellular and PCS product certification.”

Product Safety and RF Exposure CM5000 Mobile Repeater/Gateway - Basic Service Manual ix

RF Exposure Compliance and Control Guidelines and Operating Instructions

To control exposure to yourself and others and to ensure compliance with the RF 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.

Instructions:

• Transmit no more that 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 terminal generates measurable RF energy exposure only
when transmitting (in terms of measuring for standards compliance).

• Transmit only when people outside the vehicle are at least the recommended minimum

lateral distance away, as shown in Table 1, from the body of a vehicle with a properly
installed antenna. This separation distance will ensure that there is sufficient distance from a

properly installed (according to installation instructions) externally-mounted antenna to satisfy
the RF exposure requirements in the standards listed above.

Note: Table 1 lists the recommended lateral distance for bystanders in an uncontrolled
environment from the body of a vehicle with an approved, properly installed transmitting antenna
(i.e. monopoles over a ground plane, or dipoles) at several different ranges of rated radio power
for mobile terminals installed in a vehicle.

Table 1. Recommended lateral distance for bystander

Mobile terminal Rated Power
(see Note below)

Less than 7 Watts 20 cm (8 Inches)
7 to 15 Watts 30 cm (1 Ft)
16 to 39 Watts 60 cm (2 Ft)
40 to 110 Watts 90 cm (3 Ft)

Note: If you are not sure of the rated power of your terminal, contact your Motorola representative or
dealer and supply the terminal model number found on the terminal model label. If you cannot deter­mine the rated power out, then assure 90cms (3 feet) separation from the body of the vehicle.

Mobile Antenna Installation Guidelines

• These mobile antenna installation guidelines are limited to metal body motor vehicles or vehicles
with appropriate ground planes.

• Antennas should be installed in the centre area of the roof or the trunk lid taking into account the
bystander exposure conditions of backseat passengers and according to the specific instructions
and restrictions in the Radio (Terminal) Installation Manual along with the requirements of the
antenna supplier.

• Trunk lid installations are limited to vehicles with clearly defined flat trunk lids, and in some
cases, to specific terminal models and antennas. See the Radio (Terminal) Installation Manual
for specific information on how and where to install specific types of approved antennas to
facilitate recommended operating distances to all potentially exposed persons.

• Use only Motorola-approved supplied antenna or a Motorola approved replacement
antenna. Unauthorised antennas, modifications, or attachments could damage the terminal and
may result in non-compliance with RF Safety Standards.

Approved Accessories

• This terminal has been tested and meets the RF Safety Standards when used with the Motorola
accessories supplied or designated for this product. Use of other accessories may result in non­compliance with RF Safety Standards.

Compliance and Control Guidelines and Operating Instructions for Mobile Two-Way Terminals Installed as Fixed Site Control Stations

If mobile terminal equipment is installed at a fixed location and operated as a control station or as a
fixed unit, the antenna installation must comply with the following requirements in order to ensure
optimal performance and compliance with the RF energy exposure limits in the standards and
guidelines listed on previous page:

• The antenna should be mounted outside the building on the roof or a tower if at all possible.

Product Safety and RF Exposure CM5000 Mobile Repeater/Gateway - Basic Service Manual xi

• As with all fixed site antenna installations, it is the responsibility of the licensee to manage the
site in accordance with applicable regulatory requirements and may require additional
compliance actions such as site survey measurements, signage, and site access restrictions in
order to insure that exposure limits are not exceeded.

Electromagnetic Interference/Compatibility

Note: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inade­quately shielded, designed or otherwise configured for electromagnetic compatibility. It may be nec­essary to conduct compatibility testing to determine if any electronic equipment used in or around
vehicles or near fixed site antenna is sensitive to external RF energy or if any procedures need to be
followed to eliminate or mitigate the potential for interaction between the terminal transmitter and the
equipment or device.

Facilities

To avoid electromagnetic interference and/or compatibility conflicts, turn off your terminal 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.

Vehicles

To avoid possible interaction between the terminal transmitter and any vehicle electronic control
modules, such as, ABS, engine, or transmission controls, the terminal should be installed only by an
experienced installer and that the following precautions be used when installing the terminal:

1. Refer to the manufacturer’s instructions or other technical bulletins for recommendations on

terminal installation.

2. Before installing the terminal, determine the location of the electronic control modules and their

harnesses in the vehicle.

3. Route all terminal wiring, including the antenna transmission line, as far away as possible from

the electronic control units and associated wiring.

Driver Safety

Check the laws and regulations on the use of terminals in the area where you drive. Always obey
them. When using your terminal while driving, please:

• Give full attention to driving and to the road.

• Pull off the road and park before making or answering a call if driving conditions so require.

OVERVIEW CM5000 Mobile Repeater/Gateway - Basic Service Manual 11

System Controller

System Controller consists of System On Chip (SOC), ROM / RAMs, and supply voltage regulator.

The SOC (IC 601) contains Microprocessor (CPU), DSP (Digital Signal Processor) and peripheral
circuit. It is constantly working when the radio unit is turned on. It is sampling the signal cause from
switch operation of the radio and the received control signal from a TRBS which is processed by dig­ital signal processor circuit.

Once any of these signal lines have been changed the microprocessor knows what to do and then
sends out the control signal to the necessary circuit.

The system program for the Main unit is installed in the Flash-ROM (IC602).

The microprocessor in the SOC copies the program from Flash-ROM to the SDRAM (IC603) when
the radio is powered up. The microprocessor reads the program from SDRAM, and executes the
instructions accordingly.

The radio parameter of the equipment is installed in the free area of the Flash-ROM (IC602).
The temporary data of the equipment is stored in the SDRAM (IC603) and SRAM (IC604). The radio
parameters (e.g. output power adjustment, receiver adjustment) are stored in the EEPROM (IC605).

Digital Signal Processing

Digital signal processing circuit is consist of the following devices.

• Channel CODEC DSP, Voice CODEC DSP and signal processing hardware in the SOC (Sys­tem On Chip)

• ADC, DAC and Linear CODEC in the AFE (Analog Front End).

• Peripheral 10 bit ADC and 12 bit DAC

Receive Process and Decoding

Received analog signal that is converted to the IF frequency was converted to the digital signal by
the 10 bit ADC and fed to the SOC.

The digital signal is quadrature detected and filtered, then converted to the I/Q signal.

The channel CODEC recover the I/Q signal to the original signal stream by delay detection, and per­form Channel Decoding.

Then the decoded signal is fed to Voice CODEC in case of voice signal or fed to CPU in case of con­trol signal or message data.

Transmit Process and Coding

The voice CODEC DSP sends the coded voice data to the Channel CODEC. The CPU sends the
control and message data to the Channel CODEC.

The channel CODEC DSP perform channel encoding and framing the provided signal, then convert
to the I/Q signal.

The I/Q signal is filtered (roll off alpha = 0.35) by the signal processing hardware in the SOC. Then
converted to the analog signal as I/Q signal by the 12 bit DAC.

12 CM5000 Mobile Repeater/Gateway - Basic Service Manual OVERVIEW

Voice CODEC (ACELP)

Transmit analog voice data is converted to the digital signal by the linear CODEC and fed to the
Voice CODEC DSP.

The Voice CODEC DSP compresses the input digital signal by ACELP algorithm to the coded voice
data. And the data is fed to the Channel CODEC DSP.

Received digital voice data is fed to the voice CODEC DSP from Channel CODEC DSP as coded
voice data.

The Voice CODEC DSP expands the coded voice data and fed to the linear CODEC. The digital sig­nal is converted to the analog signal by the linear CODEC and output as analog signal.

Frequency Compensation

The Channel CODEC DSP calculates frequency error between the radio and base station (Master
station in DMO). It controls the VC-TCXO by DAC so as to minimize the frequency error. The VC­TCXO works as time base reference of the radio.

Transmit Power Control and Linearization

The Channel CODEC DSP controls the output power by the DAC based on the receive signal
strength and broadcast information from the base station.

Also the DSP calculates so as to minimize the distortion of the transmitter and carrier leak and con­trols the Cartesian Loop by DAC.

VC-TCXO

The reference signal for the PLL synthesizer is generated by VC-TCXO. The oscillation frequency of
the 13 MHz reference signal is fine controlled by Channel CODEC DSP. The frequency error
between the Radio Terminal and TRBS is detected and error correction signal is generated by DPS.
And the error correction signal is fed to Voltage Control circuit of the TCXO to make fine frequency
tuning.

Interface Unit

The Main unit has analog interface circuit and digital interface circuit for external interface.

Digital Interface

Digital interface is connected to the connector J902 and J904 at the rear of the Main unit. Those
connectors are combined in the one connector, but electrically independent. One is RS232 level
interface, and the other is 0 V / 3 V interface level.

The RS232 level serial communication is connected to the 7 pins connector (J904) at the rear of the
Main unit. This connector is used for the programming of the radio parameter, AT command control,
data output for the log etc.

0 V / 3 V level serial communication is connected to the 20 pins connector (J902). This connector is
used for same purpose. Features of those connectors are configured by programming. When con­necting the external equipment with the 20 pins connector (J902), appropriate level converter is
required.

ADC of the control circuit and comparator. The control circuit calculates the phase and amplitude dif­ference between the modulate signal and demodulate signal. Amplitude balance is adjusted at the
factory.

Phase difference is adjusted dynamically by phase shifter (IC319) to adjust the phase of quadrate
demodulator.

The DAC (IC702) output voltage is controlled and this voltage controls phase of the carried via buffer
amplifier (IC318).

The DC offset of the demodulated I and Q signal is corrected by adding the DC voltage from DAC
(IC702) at adder IC (IC318). Each I and Q signal is fed to the comparator and compared with refer­ence modulation signal.

Transmit signal level is controlled by operating the forward attenuator (CD301) and reverse attenua­tor (CD303) complementary.

Those attenuator should be controlled depend on the transmit power level. Output voltage of the
DAC (IC702) is changed and this voltage is fed to the buffer amplifier (IC307) and attenuator
(CD301). Then the output level of attenuator (CD301) is changed and input level of the Power ampli­fier is changed.

Due to transmit level change, the picked up signal by the coupler for quadrature demodulator is
changed. To maintain the input level of the demodulator, attenuation of the reverse attenuator
(CD303) should be change. DAC (IC702) generates the control voltage for the reverse attenuator to
maintain the input level of the quadrature demodulator.

Power Supply

The voltage regulator of the RF circuit is series drop type. DC power via the power switch is fed to
the 9 V regulator IC (IC206). This voltage is used for transmit circuit.

9 V power is fed to the 5 V and 3.3 V regulator.

5 V voltage regulator (IC207) provides 5 V power for PLL circuit. Also this voltage is switched by
transistor (TR204) and fed to PLL circuit.

3.3 V voltage regulator (IC210) provides 3.3 V power for PLL circuit.

5 V regulator (IC208) provides 5 V power for the transmitter and receiver circuit. Also this voltage is
switched by transistor (TR206) and fed to receiver circuit.

5 V regulator (IC209) provides 5 V power for the transmitter circuit. Also this voltage is switched by
transistor (TR208) and fed to transmitter circuit.

Key and display Unit

Panel CPU and Peripheral Circuit

Panel CPU (IC001) is communicating with Main CPU in the main unit. It transfer key operation to the
Main CPU and control the LCD based on the command from Main CPU.

CPU contains FLSH ROM, SD RAM interface, ADC, DAC, LCD controller and serial communication.

The Flash ROM (IC003) stores the source code, font data and portrayal bit map data. SDRAM
(IC002) is working area.

The panel CPU communicates with the main unit CPU via buffer IC (IC008). The serial communica­tion is baud rate 115.2kbps, 8 bits, non parity and 0 V / 3.3 V level.

Temperature sensor IC (IC004) is used for the temperature compensation of the LCD contrast. The
CPU reads the temperature data of temperature sensor by ADC.

White color LED driver IC (IC106) controls the intensity of the LCD back light LED.

The intensity is controlled by the output voltage of the DAC in the CPU.

Interface

Key

Switch

CPU oscillates clock frequency with crystal (X001) and multiplies 8 times internally.

The core of the CPU operates at 115.2 MHz, Bus clock operates at 57.6 MHz and peripheral block
operate at 28.8 MHz.

The Connector (J006) connects the Key/Display unit and main unit.

Microphone signal, received signal for handset, hook signal, control signal and power source of
key/display unit are connected to the J006.

Key is switched ON and OFF by metal dome contacts (SW101 to SW124).

SW101 to SW114 and SW116 to SW124 are scanned by key matrix. The emergency key SW115 is
independent input contact.

Keys are back lighted by the blue LEDs. The back light intensity is controlled as 3 levels (OFF - Low

- High) by controlling the transistor (TR107 and TR108) by the control signal of the CPU.

The power switch and volume control are adjusted by the rotary knob (SW001).

Pushing the rotary knob turns the radio on. Turning the encoder controls the audio volume and
selects the screen menu.

Other than pushing the rotary knob, pressing the emergency button will turn the radio on. In this
case an emergency call will be originated as soon as power on the radio.

2 colors LED indicator (CD102) indicates the status of the radio. The panel CPU controls the LED as
red, green or amber via the transistor (TR101 and TR102)

Connector

Microphone is connected to the Key/Display unit via the RJ-45 type connector (J005).

Microphone signal, hook signal, receive signal and function key signal for handset are connected to
the microphone connector.

Audio Circuit

The microphone signal fed to the connector (J005) is amplified by the microphone amplifier (IC107)
and fed to the main unit via interface connector (J006).

Receive signal for the handset is amplified by the audio amplifier (IC107) and fed to the microphone
connector.

Power Supply Circuit

The power supply for the Key/Display unit converts the DC 9 V from the main unit to generates each
voltage power for the Key/Display unit.

The 9 V voltage is fed to the audio circuit, indicator LED and back light LED.

The 5 V voltage is generated by the voltage regulator IC (IC102) and fed to the back light of the LCD.

The 3.3 V voltage is generated by the voltage regulator IC (IC103) and fed to the CPU, LCD module
and other digital circuit.

The 1.5 V voltage is generated by the voltage regulator IC (IC105) and fed to the CPU core.

1.5 V power will be turn on after turn ON the 3.3 V regulator.

REPLACEMENT PARTS & KITS CM5000 Mobile Repeater/Gateway - Basic Service Manual 47

APPENDIX A

REPLACEMENT PARTS & KITS

Servicing CM5000 Mobile Units

Service for the mobile units is based on the substitution method; a faulty part is replaced by a work­ing one, providing quicker service to the customer. For example, if the controller board is faulty, it is
replaced. If the mobile requires more complete testing or servicing than that is available at field level,
it is sent to the European Radio Service Centre; where it is serviced, and returned to the Regional
Service Centre.

Level 1 Maintenance

This manual covers Level 1 Maintenance: at Level 1 maintenance you replace the transceiver
and/or accessories and send the faulty transceiver and/or accessories to higher level of mainte­nance. For details, please refer to Technical Support and Further Assistance from Motorola.

The CM5000 mobiles are programmed at the factory. They cannot be tuned at the field service
level.

Level 2 and Level 3 Maintenance

The Level 2 and 3 maintenance can be only performed at the Motorola Service Center/Depot.
Contact your local Motorola G&PS for information.
