General Safety and Installation
Standards and Guidelines
WARNING:
• For safe installation, operation, service and repair of this equipment, follow the safety
precautions and instructions described below, as well as any additional safety information in
Motorola Solutions product service and installation manuals and the Motorola Solutions R56
Standards and Guidelines for Communications Sites manual (which can be obtained by
ordering CDROM 9880384V83). To obtain copies of these materials, please contact
Motorola Solutions as directed at the end of this section. After installation, these instructions
should be retained and readily available for any person operating or servicing this repeater
or working near it.
• Failure to follow these safety precautions and instructions could result in serious injury or
property damage.
• The installation process requires preparation and knowledge of the site before installation
begins. Review installation procedures and precautions in the Motorola Solutions R56
manual before performing any site or component installation. Personnel must use safe work
practices and good judgment, and always follow applicable safety procedures, such as
requirements of the Occupational Safety and Health Administration (OSHA), the National
Electrical Code (NEC), and local codes.
MN001436A01-AD
The following are additional general safety precautions that must be observed:
• To continue compliance with any applicable regulations and maintain the safety of this equipment,
do not install substitute parts or perform any unauthorized modifications.
• All equipment must be serviced by Motorola Solutions trained personnel.
• If troubleshooting the equipment while the power is on, be aware of live circuits which could contain
hazardous voltage.
• Do not operate the radio transmitters unless all RF connectors are secure and all connectors are
properly terminated.
• All equipment must be properly grounded in accordance with the Motorola Solutions R56 and
specified installation instructions for safe operation.
• Slots and openings in the cabinet are provided for ventilation. Do not block or cover openings that
protect the devices from overheating.
•
• Maintain emergency first aid kits at the site.
• Never store combustible materials in or near equipment racks. The combination of combustible
Some equipment components can become extremely hot during operation. Turn off all power
to the equipment and wait until sufficiently cool before touching.
material, heat and electrical energy increases the risk of a fire hazard.
Equipment shall be installed in a site that meets the requirements of a
"restricted access location", per (UL60950-1 & EN60950-1), which is defined as follows: "Access
can only be gained by service persons or by users who have been instructed about the reasons for
the restrictions applied to the location and about any precautions that shall be taken; and access is

through the use of a tool or lock and key, or other means of security, and is controlled by the
authority responsible for the location."
•
Burn hazard. The metal housing of the product may become extremely hot. Use caution
when working around the equipment.
•
RF energy burn hazard. Disconnect power in the cabinet to prevent injury before
disconnecting and connecting antennas.
• Shock hazard. The outer shields of all Tx and Rx RF cables outer shields must be grounded per
Motorola Solutions R56 manual.
• Shock hazard. DC input voltage shall be no higher than 60 VDC. This maximum voltage shall
include consideration of the battery charging "float voltage" associated with the intended supply
system, regardless of the marked power rating of the equipment.
• All Tx and Rx RF cables shall be connected to a surge protection device according to Motorola
Solutions R56 manual. Do not connect Tx and Rx RF cables directly to an outside antenna.
•
Compliance with National and International standards and guidelines for human exposure to
Electromagnetic Energy (EME) at Transmitter Antenna sites generally requires that persons having
access to a site shall be aware of the potential for exposure to EME and can exercise control of
exposure by appropriate means, such as adhering to warning sign instructions. See this installation
manual and Appendix A of Motorola Solutions R56.
This product complies with the requirements set forth by the European R&TTE regulations and
applicable CENELEC standards concerning human exposure to Electromagnetic Energy (EME) at
Transmitter Antenna sites. Appendix F: MOTOTRBO Repeater – EME ASSESSMENT on page 155 in
this manual includes an EME exposure analysis of a typical system configuration for this product.
For a different system configuration than the typical configuration, compliance with applicable EME
exposure standards (current versions of the EN50384 and EN50385 standards for occupational and
general public exposure, respectively) can be evaluated by either employing the method illustrated in
the typical system configuration EME exposure analysis included in Appendix F: MOTOTRBO
Repeater – EME ASSESSMENT on page 155 in this manual, or employing another suitable method
among those described in the current version of the EN50383 standard.
Once the occupational and general public compliance boundaries are determined, means to ensure
that workers and people are outside the respective boundaries, for instance using appropriate signage
or restricted access, should be implemented; if this is not possible or practically achievable for the
specific system configuration, the configuration should be modified in order to make it possible. The
R56 Standards and Guidelines for Communications Sites manual (which can be obtained by ordering
CDROM 9880384V83) provides examples of signage that can be used to identify the occupational or
general public compliance boundaries.
Refer to product specific manuals for detailed safety and installation instructions. Manuals can be
obtained with product orders, downloaded from https://businessonline.motorolasolutions.com, or
purchased through the Motorola Solutions Aftermarket & Accessory Department.
WARNING: This is a class A product. In a domestic environment, this product may cause radio
interference in which case the user may be required to take adequate measures.

Description
The Motorola Solutions SLR 5000 Series Repeater provides a modular, flexible analog and digital
station designed for today's communication systems and for the future.
The station is available for use in these configurations:
• Analog Conventional
• Digital (MOTOTRBO)
- MOTOTRBO DMR Tier 2 Conventional – Single Site
- MOTOTRBO DMR Tier 2 Conventional – IP Site Connect
- MOTOTRBO Capacity Plus Trunking
- MOTOTRBO Connect Plus Trunking
- MOTOTRBO Digital Voting
• LTR Trunking
• Passport Trunking
• MPT1327 Trunking
NOTICE: Certain software features enabled through the CPS can be configured with the Online
Help or with a regional representative. Refer to the regional Ordering Guide to determine the
features available within the respective regions.
The SLR 5000 series can either be configured as a stand-alone repeater or as a repeater connected to
a back-end network, as in the case of operating in IP Site Connect mode. As a repeater, it listens on
one uplink frequency, and then re-transmits on a downlink frequency, thus providing the RF interface to
the field subscribers. When configured for analog station operation, the repeater is designed to operate
with most existing analog systems, which enables a smooth migration to the MOTOTRBO system.
When configured for digital operation, the repeater offers additional services. The digital repeater
operates in TDMA mode, which essentially divides one channel into two virtual channels using time

slots; therefore the user capacity is doubled. The repeater utilizes embedded signaling to inform the
field radios of the busy/idle status of each channel (time slot), the type of traffic, and even the source
and destination information.
The SLR 5000 series facilitates the field replaceable unit (FRU) concept of field repair to maximize
system uptime. The FRU concept also aids in allowing the end user/maintainer to lower their inventory
costs. The base model SLR 5000 series FRUs are as follows:
• Modem FRU
• Power Amplifier FRU
• Power Supply FRU
• Front Panel FRU

Theory of Operation
The SLR 5000 series repeater provides the radio frequency (RF) link between the repeater and the
subscriber radios.
The repeater acquires inbound signals via its external receive (Rx) antenna and then amplifies, filters
and demodulates the signals into data or voice packets. From that point, the data is either forwarded to
the repeater’s transmitter to subscriber radios, and/or the data is delivered via a wired interface for
distribution to networked repeaters, consoles, or other networked infrastructure.
The SLR 5000 series repeater consists of a Modem, Power Amplifier (PA), Front Panel and Power
Supply (PS). These modules are also known as field replaceable units (FRU).
• The Modem module is comprised of three subsystems, which are the Receiver subsystem, Exciter
subsystem, and Station Control subsystem. At a high level, these subsystems are further explained
as follows:
- The Receiver subsystem is a dual heterodyne Receiver which receives the RF signal from the
subscriber’s transmitter. It then converts the resulting final intermediate frequency (IF) from an
analog signal to that of a digital word in IQ signal format. Finally, the Receiver delivers the IQ
signal, via the SSI bus, to the Station Control subsystem for demodulation. Additionally, the
Receiver subsystem also provides for its own metering and diagnostics via software, as well as
self-contained calibration (no field tuning is needed for the Receiver subsystem).

MN001436A01-AD
Chapter 1: SLR 5000 Series Repeater
- The Exciter subsystem converts a two-port base band data signal, sent over the SSI bus from
the Station Control subsystem, to an analog signal representation. The analog signal is then
modulated with a low power RF transmitter carrier that is generated by the Exciter subsystem.
The power modulated RF carrier is then amplified and delivered to the PA at an intermediate
level of approximately +36 dBm for further amplification. The Exciter subsystem and PA
constitute the transmitter of the SLR 5000 series repeater. Additionally, the Exciter subsystem
also provides its own metering and diagnostics via software, as well as a self-contained
calibration (no field tuning is needed for the Exciter subsystem).
- The heart of the Station Control subsystem is the Texas Instruments DM8148 Host/ DSP
processor. In general, the SCM controls the entire coordination of the repeater functions.
Specifically, the Station Control subsystem provides for the following functionalities:
+ Contains and runs the preloaded repeater software
+ Manages inbound and outbound RF and Audio traffic
+ Provides an on-board USB port for local configuring, alignment and diagnostics via the
following applications:
• Customer Programming Software (CPS)
• Tuner application
• Repeater Diagnostic and Control (RDAC) software
+ Provides an Ethernet port for IP site connectivity and remote RDAC
+ Provides GPIO connectivity for third party controller interfaces
+ Provides for analog repeater audio connectivity
+ Data and Control to the Receiver subsystem via the SPI and SSI respectively
+ Data and Control to the Exciter subsystem via the SPI and SSI respectively
+ Control of the PA’s set power via the SPI
+ Configuration and fault management of all subsystems including the PS and PA
+ Generates the internal station reference
+ Provides control of the front panel module’s indicator LEDs.
- The PA module amplifies the intermediate level modulated RF signal from the Modem. It then
delivers the amplified signal to the transmitter antenna port at a power level within the rated
power band of the repeater, for transmission to the subscriber radios. In addition to its primary
task of amplification, the PA provides the following hardware functions for the repeater.
+ Harmonic attenuation
+ Inter-modulation attenuation (IMA) suppression
+ VSWR detection
+ RF power control (primary means)
+ Meters for diagnostics
+ Power rollback for temperature, VSWR, and voltage
+ Self-Contained calibration (no field alignment is needed for PA)
- The Front Panel module provides LED indications for general assessment of the status and
operational condition of the repeater. Additionally, the front panel also provides a USB service
port for configuration and alignment of the repeater.
- The PS Module provides DC power to the Modem, PA and Front Panel. It can also be used to
provide auxiliary power (nominal 13.6 VDC) to a number of third party controllers. Additionally, it
can operate in three different input modes:

+ AC with Battery Revert
In addition to providing power to the noted FRU and controllers, the PS also provides the following:
• AC Failure detect signaling to the Modem
• Output over-current protection
• Integrated 2 stage 3 amp battery charger
Further details can be found in the individual sections of the respective FRU chapters of this manual.
1.7
Basic Repeater Level Troubleshooting – RDAC and LEDs
Diagnostic tests are available for the Modem, PA, and Power Supply Modules. If a problem occurs
during station operation, it is logged as an alarm that is read with the Repeater Diagnostic and Control
application (RDAC).
Figure 5: RDAC Diagnostic Screen
The station operator will then evaluate the problem locally or remotely, as the station maintains an
Alarm Log with the name of the alarm that has failed since the last power up. Via the RDAC
application's Alarm Log, the alarm messages will aid in identifying the FRU that failed along with the
fault condition.
After booting up the repeater, the seven LEDs (Power/Status, Tx Slot 1, Tx Slot 2, Rx Slot 1, Rx Slot 2,
Network, and Reference LEDs) will flash in unison.
The general status and condition of the SLR 5000 series repeater can be obtained by observing the
seven LED indicators on the front panel. Table 8: Front Panel LED indicators on page 45 shows the
LED symbols and their meaning, while Table 9: SLR 5000 Series Front Panel LED Definitions on page

Transmitter Exciter Subsystem
The Exciter Subsystem in the Modem Module (in conjunction with the Power Amplifier Module)
provides the transmitter functions for the station. The Exciter circuitry generates a low-level modulated
Radio Frequency (RF) signal which is input to the Power Amplifier (PA) module for further amplification
and output to the transmit antenna. A coaxial cable is used to connect the Tx exciter output to the PA
module. See Figure 8: Modem Module Connector Locations on page 52 for the exact location of this
connector. The Exciter Module interfaces directly with the controller section, which provides control
signals and monitoring, and routes transmit data to the Exciter.
The RF carrier is generated by a frequency synthesizer consisting of synthesizer circuitry and VoltageControlled Oscillator (VCO) circuitry. Exciter circuit control signals, monitoring, and audio processing
are handled by the controller section of the Modem Module. The power leveling circuitry of the
transmitter system is located in the Power Amplifier Module and passed onto the exciter stages
through the PA-Modem interface flex cable. See Figure 8: Modem Module Connector Locations on
page 52 for the location. Included in the exciter section are:
• Frequency Synthesizer Circuitry – Consists of a phase-locked loop and Voltage-Controlled
Oscillator (VCO), generates a modulated RF signal at the transmitter carrier frequency.
• RF Isolation Switch – Allows the controller section to turn on/off the Exciter RF input signal which
greatly reduces the signal supplied to the Power Amplifier module.
• Analog to Digital Converter (ADC) Circuitry – Converts the analog Exciter status signals to the
digital format for transfer, upon request, to the controller section of the Modem Module.
• Low Level Amplifiers – Amplify and buffer the modulated RF signal from the VCO for delivery to the
Power Amplifier Module.

Description
The Power Amplifier Module is described in this section. A general description, identification of inputs
and outputs and functional theory of operation are provided. The information provided is sufficient to
give service personnel a functional understanding of the module, allowing maintenance and
troubleshooting to the module level.
4.1.1
General Description
The Power Amplifier (PA) is a forced convection-cooled RF power amplifier. It accepts a low-level
modulated RF signal from the Exciter Module, and amplifies it for transmission via the site transmit
antenna port. The PA is non-linear, and is therefore used for Continuous Wave (CW) applications only.
The output power is continually monitored and regulated by a feedback and control loop, with a power
output control voltage being generated by the transmitter control circuitry located on the PA. All
configuration and control signals are connected to the modem module via the flex connected between
the modules.
NOTICE: The power amplifier cooling fan is replaceable and external to the power amplifier
itself. See SLR 5000 Series Maintenance and Disassembly/Reassembly on page 97 for
replacement details.

Description
In this chapter, a general description, performance specifications, and identification of the inputs and
outputs are given for the power supply. The information provided is sufficient to give service personnel
a functional understanding of the module, allowing maintenance and troubleshooting to the module
level. (See SLR 5000 Series Maintenance and Disassembly/Reassembly on page 97 for detailed
removal or installation procedures for all modules in the SLR 5000 series repeater.)
5.1.1
General Description
The power supply, with front-to-rear airflow, operates from either an AC or DC input and provides the
DC operating voltage for the SLR 5000 series repeater. The power supply also provides an integrated
battery charger to maintain the charge on a negatively grounded 12 VDC (nominal) battery system.
Figure 17: Front View of the SLR 5000 Series Power Supply on page 64 displays the front and rear
views of the SLR 5000 series Power Supply.
Additionally, the power supply affords the following performance features:
• Power Factor Correction (PFC) – aids in lowering the ampacity requirements of the AC power
source.
• Over-Voltage Protection (OVP) – lowers the risk of damaging the repeater should input AC or DC
levels approach damaging levels.
• Over-Current Protection (OCP) – aids in preventing a cascaded failure within the repeater.
• Reverse Polarity Protection – aids in preventing damage to the repeater due to installation mishaps.
• Configurable Battery Charger Voltage – tailors the float voltage to your battery manufactures
charging recommendations.
• Configurable Low Voltage Disconnect (LVD) – tailors the battery disconnect voltage to your battery
manufactures recommendations.
• Configurable Power Source Preference – when both AC and DC sources are present (and within
their respective operational bounds), this feature allows one to select the primary power source the
repeater uses.
• Battery Revert – should the AC source be interrupted, this function allows the power supply to
seamlessly transfer to a DC source until the AC source is restored. This results in uninterrupted
radio service for as long as DC power can be provided.
NOTICE: A user supplied external 12 V (nominal) battery system is required to support the
battery backup feature so that when the AC power fails, the SLR 5000 series repeater can
be powered from a DC battery source if it is connected to the PS.
NOTICE: The power supply cooling fan is replaceable and external to the power supply
itself. See SLR 5000 Series Maintenance and Disassembly/Reassembly on page 97 for
replacement details.

SLR 5000 Series Performance Check
or Testing
9.1
General
The SLR 5000 Series Repeater meets published specifications through the manufacturing process by
utilizing high-accuracy laboratory-quality test equipment. The recommended field service equipment
approaches the accuracy of the manufacturing equipment with few exceptions. This accuracy must be
maintained in compliance with the equipment manufacturer’s recommended calibration schedule.
NOTICE: Although these repeaters function in digital and analog modes, all testing is done in
analog mode. Digital Repeater tests can be performed using an Aeroflex 3900 Series Service
Monitor, if the DMR Digital Repeater Test Option is purchased. This auto testing could be
performed in lieu of the following Manual testing.
9.2
Transmitter Testing
CAUTION: The SLR 5000 Series Repeater needs to be taken out of service in order to carry
out performance testing procedures. Unless the repeater is already out of service, it is
recommended to perform the procedures during off-peak hours in order to minimize disruption
of service to the system subscribers.
9.2.1
Introduction
While most module faults can be detected by running the repeater diagnostics, the following procedure
provides a more traditional method of troubleshooting the transmitter circuitry.
This procedure allows the service technician to make minor adjustments and verify proper operation of
the SLR 5000 Series Repeater's transmit circuitry, including:
• Exciter Section of Modem Module
• Power Amplifier Module
• Power Supply Module
In general, the transmitter circuitry is exercised by injecting and measuring signals using a Service
Monitor (or equivalent). Incorrect measurement values indicate a faulty module(s); measurement
values within the acceptable range verify proper operation of the listed modules and circuitry.
9.2.2
Test Equipment
The following test equipment are required to perform the procedure:
• Aeroflex 3920 Digital Radio Test Set (or equivalent)
• Microphone (GMMN4063_)
• Power Meter and Sensor
• Station Rear Accessory Test Cable

9.2.3
Verifying Transmitter Circuitry Procedure
Procedure:
1 Connect and set up test equipment as shown in Figure 37: Test Equipment Setup for Verifying
Transmitter Circuitry on page 85.
2 Apply input power (AC or DC) to the repeater. The power supply, modem, and PA fans should
run a few seconds to confirm fan operation.
3 Press the PTT switch of the microphone and observe the PA Keyed LED indicator on the
Repeater Front Panel.
If PA Keyed fails to light, suspect the following:
• Faulty Power Amplifier Module
• Faulty Modem Module
• Loose or bad Exciter-to-PA RF cable
• Loose or bad PA-to-antenna RF output cable
• Improperly terminated PA RF output cable
• Faulty Power Supply Module
4 Measure output power by pressing the PTT button and observing reading on an in-line
wattmeter.
• If PA output is not at proper power (as set for particular site), adjust the output power as
described in the CPS online help.
5 If PA output power is proper, set up the Service Monitor for spectrum analyzer display. Press the
PTT button and observe the display. The display should show a single frequency carrier:
• If the display shows multiple carriers evenly spaced about the carrier, suspect a faulty Exciter
module or PA module.
• If the display shows a solid carrier but it is off frequency, suspect the following:
• Faulty Modem Module
• Faulty external 5/10 MHz reference source (if used)
• If the display shows a single carrier moving erratically, suspect a faulty Modem Module.
6 If display is proper, set up Aeroflex 3900 Series Communications System Analyzer to display
modulation. Using the microphone, push the PTT button and speak into the microphone. Verify
that the display shows an audio signal.
• If the proper display is not obtained, suspect faulty SCM or Exciter Module
7 Set the Aeroflex 3900 Series Communications System Analyzer for GEN/MON MTR. Press the
PTT button and speak loudly into the microphone to cause maximum deviation. Display should
read:
• 4.60 kHz maximum for a 25 kHz system
• 3.68 kHz maximum for a 20 kHz system
• 2.30 kHz maximum for a 12.5 kHz system
If the proper display is not obtained, suspect faulty SCM or Exciter Module.
8 This completes the Verifying Transmitter Circuitry test procedure. If all displays and
measurements are correct, the transmitter circuitry may be considered to be operating properly.

Verifying Receiver Circuitry Procedure
Procedure:
1 Connect equipment as shown in Figure 38: Test Equipment Setup for Verifying Receiver
Circuitry on page 86.
2 Set the Service Monitor to generate a 1.0 μV (-107 dBm) FM signal at the Receiver frequency,
modulated by a 1 kHz tone at 3 kHz deviation for 25/30 kHz channel spacing, or 1.5 kHz
deviation for 12.5 kHz channel spacing. The 1 kHz tone should be audible through the external
speaker. If no audio is heard, suspect the following:
• Faulty Modem Module
• Faulty antenna-to-Receiver preselector RF cable (for the repeater with external metal
preselector)
• Faulty Service Monitor-to-station RF cable
• Faulty Antenna Relay (If installed)
• Faulty Preselector (If installed)
• Rear Panel to Modem Module cable unplugged
• Faulty rear panel to Modem Module Cable
3 If Audio is heard (the audio volume can be adjusted on the rear of the HSN1006), look at the
Oscilloscope window on the Aeroflex 3920 (or a separate O-Scope) and verify that the Audio
level Sine Wave measures between 0.75 to 1.5 Vpp. If not, connect to Tuner and increase the
RX Audio level until this is achieved. If the level cannot be obtained, suspect a faulty Modem.
4 Move the BNC cable from the Scope CH 1 input to the Audio 1 input.
5 Change System Monitor injection signal level to the noted levels in .
6 Measure the Receiver 12 dB SINAD sensitivity.
• If the SINAD level is less than 12 dB, suspect faulty Modem.
7 This completes the Verifying Receiver Circuitry test procedure. If all displays and measurements
are correct, the Receiver circuitry may be considered to be operating properly. Remove test
equipment, restore the repeater to normal service, and (if applicable) return to the
troubleshooting flow chart to resume troubleshooting sequence.

SLR 5000 Series Maintenance and
Disassembly/Reassembly
11.1
Introduction
This chapter provides details about the following:
• Routine maintenance
• Preventive maintenance (inspection and cleaning)
• Safe handling of CMOS and LDMOS devices
• Disassembly and reassembly of the repeater
• Repair procedures and techniques.
11.2
Routine Maintenance
NOTICE: Clean the repeater with a soft dry cloth while in service.
The SLR 5000 Series Repeater and ancillary equipment have been designed with state-of-the-art
technology and operate under software control, thus requiring minimal routine maintenance. Virtually
all repeater operating parameters are monitored and self-corrected by the Modem and the firmware it
runs, which makes adjustments and tuning virtually unnecessary.
Provided that the equipment is installed in an area which meets the specified environmental
requirements, the only routine maintenance task required is the calibration of the repeater reference
oscillator circuit.
11.3
Preventive Maintenance
Periodic visual inspection and cleaning is recommended.
11.3.1
Inspection
Check that the external surfaces of the SLR 5000 Series Repeater are clean, and that all external
controls and connections are in order. It is not recommended to inspect the interior electronic circuitry.
11.3.2
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 SLR 5000 Series Repeater. External surfaces
include the top cover and repeater enclosure.
Periodically clean smudges and grime from exterior enclosure. Use a soft, non-abrasive cloth
moistened in a 0.5% solution of mild dishwashing detergent and water solution. Rinse the surface
Send Feedback 97
MN001436A01-AD
Chapter 11: SLR 5000 Series Maintenance and Disassembly/Reassembly
using a second cloth moistened in clean water, and clean any dirt or debris from the fan grill and
louvers on the front side.
NOTICE: Internal surfaces should be cleaned only when the repeater is disassembled for
service or repair.
The only factory recommended liquid for cleaning the printed circuit boards and their components is
isopropyl alcohol (100% by volume).
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 repeater. 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. Once the cleaning process is complete,
use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol to the
top cover and repeater enclosure.
NOTICE: Always use a fresh supply of alcohol and a clean container to prevent contamination
by dissolved material (from previous usage).
11.4
Safe Handling of CMOS and LDMOS Devices
Complementary metal-oxide semiconductor (CMOS) and laterally diffused metal-oxide semiconductor
(LDMOS) devices are used in this family of stations, 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/LDMOS circuits and are especially important in low
humidity conditions.
DO NOT attempt to disassemble the repeater without first referring to the following CAUTION
statement.
98 Send Feedback
MN001436A01-AD
Chapter 11: SLR 5000 Series Maintenance and Disassembly/Reassembly
CAUTION: This repeater contains static-sensitive devices. Do not open the repeater unless you
are properly grounded. Take the following precautions when working on this unit:
• Store and transport all CMOS/LDMOS devices in conductive material so that all exposed
leads are shorted together. Do not insert CMOS/LDMOS 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/LDMOS device. We
recommend using the Motorola Solutions Static Protection Assembly (part number
0180386A82), which includes a wrist strap, two ground cords, a table mat, and a floor mat,
ESD shoes and an ESD chair.
• 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 Solutions part number
4280385A59).
• Do not wear nylon clothing while handling CMOS/LDMOS devices.
• Do not insert or remove CMOS/LDMOS devices with power applied. Check all power
supplies used for testing CMOS/LDMOS devices to be certain that there are no voltage
transients present.
• When straightening CMOS/LDMOS pins, provide ground straps for the apparatus used.
• When soldering, use a grounded soldering iron.
• If at all possible, handle CMOS/LDMOS 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.

Disassembly
11.5.1
Disassembly – General
Station modules suspected of being faulty must be replaced with known good modules to restore the
repeater to proper operation. The following are typical procedures to remove each of the repeater
modules.
Procedure:
1 Power cord (and battery backup power, if used) and all external cables must be disconnected
before opening up repeater. Label each removed cable as required to ensure it is properly
reconnected.
2 Take the proper grounding precautions as stated in Safe Handling of CMOS and LDMOS
Devices on page 98.
3 When disassembling repeater, retain all screws for reuse.
The following tools are required for disassembling and reassembling the repeater:
• Torque Drivers (T10, T20 and T30). See Torque Charts on page 117 for the different size
fasteners of screw torques.
• Hex Nut Drivers (16 mm, ¾ inch [19 mm])
• Needle Nose Pliers (optional)
• Torque Gauge capable of measuring torque up to 20 in-lb (2.3 N-m) within
+/- 1 in-lb (0.1 N-m)
