Intrinsically Safe Radio Information

2.1 FMRC Approved Equipment

Anyone intending to use a radio in a location where hazardous concentrations of flammable materials exist (hazardous atmosphere) is advised to become familiar with the subject of intrinsic safety and with the National Electric Code NFP A 70 (National Fire Protection Association) Article 500 (hazardous [classified] locations).

An Approval Guide, issued by Factory Mutual Research Corporation (FMRC), lists manufacturers and the products approved by FMRC for use in such locations. FMRC has also issued a voluntary approval standard for repair service (“Class Number 3605”).

FMRC Approval labels are attached to the radio to identify the unit as being FM Approved for specified hazardous atmospheres. This label specifies the hazardous Class/Division/Group along with the part number of the battery that must be used. Depending on the design of the portable unit, this FM label can be found on the back or the bottom of the radio housing. The FM Approval mark is shown below.

2-1

• Do not operate radio communications equipment in a hazardous

A R N I N

Radios must ship from the Motorola manufacturing facility with the Intrinsically Safe, hazardous atmosphere capability and FM Approval labeling. Radios will not be “upgraded” or converted to Intrinsically safe, and or labeled in the field, after it has been shipped from the manufactu ring location.

atmosphere unless it is a type especially qualified (for example, FMRC Approved) for such use. An explosion or fire may result.

• Do not operate an FMRC Approved 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 a radio off before removing or installing a battery or accessory.

• Do not disassemble an FMRC Approved Product unit in any way that exposes the internal electrical circuits of the unit.

2-2 Intrinsically Safe Radio Information

Modifications can only be made by the original product manufacturer (Motorola) at one of its FM audited manufacturing facilities.

• Failure to use an FMRC Approved portable radio unit with an

A R N I N

FMRC Approved battery or FMRC Approved accessories specifically Agency approved for that product may result in the dangerously unsafe condition of an unapproved radio combination being used in a hazardous location.

• Unauthorized or incorrect modification of an FMRC Approved Product unit will negate the Approval rating of the product.

2.2 Repair of FMRC Approved Products

REPAIRS FOR MOTOROLA PRODUCTS WITH FMRC APPROVAL ARE THE RESPONSIBILITY OF THE USER.

You should not repair or relabel any Motorola- manufactured communication equipment bearing the FMRC Approval label (“FMRC Approved Product”) unless you are familiar with the current FMRC Approval standard for repairs and service (“Class Number 3605”). Repairs and service to be done FM audited locations.

A R N I N

The following are key definitions, from the FMRC’s Approval Standard Class Number 3605, 1994.

2.2.1 Repair

A repair constitutes something done internally to the unit that would bring it back to its original condition-Approved by FMRC. A repair should be done in an FMRC audited facility. Items not considered as repairs are those in which an a ction is perform ed on a unit which do es not require the outer casing of the unit to be opened in a manner which exposes the internal electrical. You do not have to be an FMRC audited Repair Facility to perform these actions.

2.2.2 Relabeling

The repair facility shall have a method by which the replacement of FMRC Approval labels are controlled to ensure that any relabeling is limited to units that were originally shipped from the Manufacturer with an FM Approval label in place. F MRC Ap pr oval labe ls sh all not be stocked by the repair facility. An FMRC Approval label shall be ordered from the original manufacturer, as needed, to repair a specific unit. Replacement labels may be obtained and applied by the repair facility, provided there is satisfactory evidence that the unit being relabeled was originally an FMRC Approved unit. Verification may include, but is not limited to: a unit with a damaged Approval label, a unit with a defective housing displaying an Approval labe l, or a customer invoice indicating the serial number of the unit and purchase of an FMRC Approved model.

• Incorrect repair or relabeling of any FMRC Approved Product unit 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.

Intrinsically Safe Radio Information 2-3

2.2.3 Do Not Substitute Options or Accessories

The Motorola communications equipment certified by Factory Mutual is tested as a system and consists of the FM Approved portable, FM Approved battery, and FM Approved accessories or options, or both. This FM Approved portable and battery combination must be strictly observed. The re must be no substitution of items, even if the substitute has been previously Approved with a different Motorola communications equipment unit. Approved configurations are listed in the FM Approval Guide published by FMRC, or in the product FM product listing. This FM product listing is shipped from the manufacturer with the FM Approved radio and battery combination.

Maintenance

3.1 Introduction

This chapter provides details about the following:

l Preventive maintenance (inspection and cleaning) l Safe handling of CMOS and LDMOS devices l Disassembly and reassembly of the radio l Installation of Optional Retrofit Kit l Installation of Option Boards

3.2 Preventive Maintenance

The radios do not require a scheduled preventive maintenance program; however, periodic visual inspection and cleaning is recommended.

3-1

3.2.1 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.

3.2.2 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: Internal surfaces should be cleaned only when the radio is disassembled for service

or repair.

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).

CAUTION: Certain chemicals and their vapors can have harmful effects on certain

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

Cleaning External Plastic Surface

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 (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 sh ould direct the

3-2 Maintenance

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. Afte r 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).

3.3 Safe Handling of CMOS and LDMOS Devices

Complementary metal-oxide semico nductor (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 fir st referring to th e 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

a u t i o

unit:

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

leads are shorted together. Do not insert CMOS devices into conventional plastic “snow” trays used for storage and transportation of other semiconductor devices.

l Ground the working surface of the service bench to protect the CMOS d evice. W e

recommend using the Motorola Static Protection Assembly (part number 0180386A82), which includes a wrist strap, two ground cords, a table mat, and a floor mat.

l Wear a conductive wrist strap in series with a 100k resistor to ground.

(Replacement wrist straps that connect to the bench top covering are Motorola part number RSX-4015.)

l Do not wear nylon clothing while handling CMOS devices. l Do not insert or remove CMOS devices with power applied. Check all power

supplies used for testing CMOS devices to be certain that ther e ar e no voltage transients present.

l When straightening CMOS pins, provide ground straps for the apparatus used. l When soldering, use a grounded soldering iron. l If at all possible, handle CMOS devices by the package and not by the leads. Prior

to touching the unit, touch an electrical ground to remove any static charge that you may have accumulated. The package and substrate may be electrically common. If so, the reaction of a discharge to the case would cause the same damage as touching the leads.

3.4 Repair Procedures and Techniques — General

Parts Replacement and Substitution

When damaged parts are r eplaced, identica l p art s sh ould be used. If the ide ntical replacement p art 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 “Piece Parts” section of this manual (See page 1-2).

Maintenance 3-3

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:

l Avoid accidentally getting solder in the connector. l Be careful not to form solder bridges between the connector pins. l Examine your work closely for shorts due to solder bridges.

Flexible Circuits

The flexible circuits are made from a different material than the rigid boards, and require different soldering techniques. Excessive prolonged heat on a flexible circuit can damage the mater ial. Therefore, avoid excessive heat and excessive bending.

For parts replacement, use the ST-1087 Temperature-Controlled Solder Station with a 600-700 degree tip, and use small diameter solder such as ST-633. The smaller size solder will melt faster and require less heat to be applied to the circuit.

To replace a component on a flexible circuit:

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

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.

3.5 Disassembling and Reassembling the Radio — General

Since these radios may be disassembled and reassembled with the use of only four (board to casting) screws, it is important to pay particular attention to the snaps and tab s, and how parts align with each other.

The following tools are required for disassemb ling the radi o :

l 3/16” flat blade screwdriver l Penknife-size screwdriver l TORX™ T6 screwdriver

If a unit requires more complete testing or serv ic e than is customarily performed at the basic level, send this unit to a Motorola Authorized Service Center. (See Chapter, section 1.2.4 Technical Support on page 1-3 for a list of authorized service centers.)

The following disassembly procedures should be performed only if necessary: section 3.6.2 Chassis Assembly/Disassembly on page 3-6 section 3.6.3 Keypad, Display, and Keypad/PassPort/Option Board Disassembly on page 3-6 section 3.6.4 Speaker, Microphone, and Universal Connector Flex Disassembly on page 3-8 section 3.6.5 PTT Disassembly on page 3-9 section 3.6.6 Control Top Disassembly on page 3-9 section 3.7.7 DTMF Retrofit Kit Procedure (Optional Upgrade Procedure) on page 3-12 section 3.7.8 Option Board Installation on page 3-13

Chapter 4 Transceiver Performance Testing

4.1 General

These radios meet published specifications through their 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 manufacturer’s recommended calibration schedule.

4.2 RF Test Mode

When the radio is operating in its normal environment, the radio’s microcontroller controls the RF channel selection, transmitter key-up, and receiver muting. However, when the unit is on the bench for testing, alignment, or repair, it is removed from its normal environment and cannot receive commands from its system. Therefore, the internal microcontroller does not key the transmitter or unmute the receiver. This prevents the use of a normal tuning procedure. To solve this problem, a special “test mode” is incorporated into the radio.

Note 1: On VHF/UHF, LTR models, the radio must be in either conventional or LTR mode. Note 2: The test mode procedure that follows assumes that the Customer Programming Software

Front Panel Access screen has both the FPA and RF TEST boxes selected. Select from the programming screen to enable or disable certain features of the radio RF test mode.

l FPA entry not selected blocks all test modes. l FPA entry selected and RF TEST not selected blocks RF test mode. l FPA entry selected and RF TEST selected enables all test modes.

5.4 Cloning (Conventional and LTR)

Cloning is the same for both the Conventional and LTR radio. Cloning is the process of copying the content of one radio (source radio) into another radio (ta rget radio). Radio content refers to systemtype features such as frequency, squelch type options, trunking, etc.

NOTE: Cloning can be performed only on radios with identical model numbers and software options. Radio functionality inherent in one radio cannot be cloned to another radio that does not contain the

same functionality. Tuning and alignment information are not transferable and are not affecte d by cloning.

Signaling Identification Numbers (IDs) are duplicated in the cloning process. Unique IDs may be assigned with the CPS.

NOTE: Unsuccessful cloning attempts will not damage the radio. Procedure:

1. Turn source and target radios off.

2. Connect cloning cable to side connector of both radios.

3. Turn on target radio.

4. On source radio, simultaneously press ‘side buttons 1 and 2’, shown in Figure 5-3, then turn radio on. Both radios produce a “clone-entry” tone and turn on their green LEDs. Display radios show “Cloning To” (sourc e ra dio ) an d “ Program” (target radio).

5. Release both side buttons. The electronic transfer process begins and will take approximately one to three minutes.

6. When cloning is completed, both radios reset themselves and turn their green LEDs off. The

5-4 Radio Tuning, Programming, Cloning, Lowband Antenna Cutting Procedure, PassPort Tone Options, and Diagnostic Functions

source radio produces a “clone-exit” tone and displays “Clone Complete”.

7. Turn both radios off.

8. Disconnect the cloning cable from both radios and turn them on for normal operation.

5.4.1 Error Codes (Display Radios Only)

l “ERR: Mismatch” - The model numbers or the code plug versions are not the same for both

radios. Cloning cannot be performed.

l “ERR: Timeout” - Communication between the two radios was not established or was disrupted

during the cloning process. If this occurs, check the cloning cable and all connections. Repeat the cloning procedure.

5.5 Cloning (Privacy Plus)

This function is used to copy codeplug information from one radio to another . A radio and RIB must be properly connected to the computer and power turned on before you attempt the PROGRAM function. The time required to PROGRAM a codeplug will depend on the computer and the size of the codeplug you are programming. Only radios with the same model number, protocol option and codeplug version may be cloned. Trunked radios may not be cloned unless System Keys have been loaded for each trunking system ID. Tuning and alignment information are not transferable and are not affected by cloning. Signalling Identification are du plicated in the cloning process. Unique IDs may be assigned with the CPS.

Radio Tuning, Programming, Cloning, Lowband Antenna Cutting Procedure, PassPort Tone Options, and Diagnostic Functions 5-5

WARNING: Do NOT turn off the radio or disconnect it from the computer while attempting to PROGRAM the codeplug. Interrupting the programming process WILL DESTROY the code-

plug contents and completely DISABLE the radio

A R N I N

Procedure:

1. Use the READ RADIO function to read the radio codeplug to be cloned. i.e. the “Source” codeplug.

2. If required, enter the Individual ID’s for the new radio. Trunking system keys (or FTR Key) are required for cloning the Trunking System Data.

3. If required, go to the SDF merge screen, to merge SDF Trunking System Data.

4. Connect “Target” radio to the computer and press READ SERIAL NUMBER button to read the “Target” radio’s serial number. This number must be different from the “Source” codeplug, or the cloning progress will fail.

5. Connect “T arget” rad io to the computer, and press the PROGRAM button to program the “Source” codeplug into the “Target” radio.

6. The CPS will validate the code plug.

7. If it fails a warning screen will be displayed informing of the incompatibility between the CPS and code plug, otherwise the information is written into the radio’s code plug.

5.6 Cloning (PassPort)

Cloning of PassPort data in the HT1250•LS+ may only be accomplished via the PPCPS. In order to “clone” the contents of one radio into another radio, the user must attach the first radio to the RIB cable and read the contents of the PassPort personality by pressing the “Read Device” icon on the toolbar (or by choosing “Read Device” from the file menu and selecting the proper COM port). The user should then select each PassPort zone and change the MIN for each zone. He/She may then attach the second radio to the RIB cable and write the personality into it by pressing the “Write Device” icon on the toolbar (or by choosing “Write De vice” from the file menu a nd choosing the proper COM port). Alternatively, the information may be cloned to multiple radios by saving the personality data to a file. The file may, at a later time, be re-read and the MIN may be ch anged for ea ch zone an d then written to the radio through the procedure described above. Care must always be taken by the user to ensure that the MIN is unique for each radio to avoid undesirable results in the system.

5.8 HT1250•LS+ PassPort Tone Options

In order to provide more detailed information about the radio’s state to a user or service technician various Tones and Display options are available.

One Tone option is a short low pitched tone that sounds whenever the radio loses contact for any reason with its registered PassPort site and begins to se arch for another site. This Tone is enabled by the “Enable LOS Search start tone” option.

Service technicians who are determining system coverage and RSSI settings may want to be able to discriminate between the LOS (Loss of System) for complete loss of data from the site or when the site RSSI drops below required levels. A second T one following the first LOS Tone indicating that LOS was caused by complete LOS of Passport data from the site and not low.

RSSI can be activated with the “Enable LOS CRC Search start tone” option. Enable just the “Enable LOS Search start tone” option. Allow the radio to register. Turn off the Home

repeater. The radio will sound a single tone and st art to search. Turn on the Home repeater. Allow the radio to register. Remove the antenna. The radio will sound a single tone and start to search. Replace the antenna.

Enable the “Enable LOS CRC Search start tone” option also. Allow the radio to register. Turn off the Home repeater. The radio will sound two tones and st art to search. T urn on the Home repeater. Allow the radio to register. Remove the antenna. The radio will sound a single tone and start to search.

5.9 HT1250•LS+ Special Diagnostic Functions

Some special diagnosis functions can be turned on “as needed” basis by accessing the “Service Menu”. In order to enter this menu please proceed as follows

1) Press the Menu Key. (You don't need to be registered).

2) Quickly press the P1 then the P2 key.

3) Service Menu appears on the screen.

4) Press the Menu key to select it. A series of functions then become available to you as you scroll up and down. They are as follows: PassPort ESN: Enter the Service Menu and using the Up/Dn keys scroll to “PassPort ESN”. Press

the Select key. Use the Up/Dn and Select Keys to activate or deactivate this function. This function momentarily displays the radio's PassPort Electronic Serial Number.

PassPort Information Report - Enter the Service Menu and using the Up/Dn keys scroll to “Repor t”. Press the Select key. The display will sequentially show, the search method preference, the number of NearNeighbors from the last registered site neighbor list, All Neighbors, the total number of unique stored Neighbor frequencies and then display the known list of Neighbor Frequencies. The report will complete and the radio will search and re-register.

Monitor - This Service Menu option defeats Pa ssPort coded squelch and allows a technician to hear all transmissions on the system. This function can be enabled or disabled using the PassPort CPS (PPCPS).

Show RSSI - Enter the Service Menu and using the Up/Dn keys scroll to “Show RSSI”. Press the Select key. Use the Up/Dn and Select Keys to activate or deactivate this function. This diagnostic momentarily displays the ASID and RSSI of all received site IDLE messages in the format “WXXXYYY-ZZZ” where W is a “-” on an Idle channel and a “+” on a busy one, XXX is the ASID of the site, YYY is the RSSI of the message just received and ZZZ is the current running average RSSI. This can be helpful in determining RSSI roaming settings. Also while this feature is enabled and the radio is searching, each new search frequency is momentar ily displa yed i n order to tr ack the radio's prog ress through the known frequencies.

Search Freq-(Enter Search Frequencies): Enter the Service Menu and using the Up/Dn keys scroll to “Search Freq”. Press the Select key. Using the numeric keys and Left (P1) key for backup/delete a nd

the “*” key for the decimal point, enter the desired Search Frequency in MHz. Press the Select key when the entry is complete or the Escape/Exit Key to exit the function without entering a search frequency. After pressing the Select key the radio will exit the Menu mode and begin searching the entered frequency for a period of time equal to twice the initial search delay. This utility allows a new radio or a radio with an empty Neighbor List Almanac to search an initial frequency other than its Home Frequency or a Seed List Frequency. This can be helpful when programming and delivering a new radio to a customer in an area not served by a site on his Home Frequency.

Clear Almanac – (Clear Neighbor list Almanac): Enter the Service Menu and using the Up/ keys scroll to “Clear Almanac”. Press the Select key. The stored Neighbor frequencies will be erased. This utility allows clearing obsolete Neighbor frequencies collected.

Chapter 6 Power Up Self-Test

6.1 Error Codes - Conventional and LTR Radios

Turning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM hardware, and EEPROM checksum. If these checks are successful, the radio generates two highpitched self-test pass tones, or a musical tone (selected in CPS). If the se lf-test is not successful, one low-pitched tone is heard. Radios with displays are able to display the error codes. The displayed error codes and related corrections are listed as follows:

Table 6-1: Power-up Display Codes - (Conventional Radios)

6.2 Error Codes - Privacy Plus

At power-up, the radio performs cursory tests to determin e if its basic electronics and software are in working order. Problems detected during these tests are presented as error codes on the radio display. The presence of an error code should prompt the user that a problem exists and that a service technician should be contacted. Self-test errors are classified as either fatal or non-fatal. Fat al errors will inhibit user operation, non-fatal errors will not. Use Table 6-2: Power-up Display Codes to aid in understanding particular power-up error code displays.
