1-4 1.3 Introduction Radio Model Information The model number and serial number are located on a label attached to the back of your radio. You can determine the RF output power, frequency band, protocols, and physical packages. The example below shows one portable radio model number and its specific characteristics. Table 1-1:Radio Model Number (Example: AAH25KDC9AA3AN) Type of Model Unit Series H H = Portable A or LA = Motorola Internal Use AA or LA 25 Freq.
2-1 Chapter 2 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 NFPA 70 (National Fire Protection Association) Article 500 (hazardous [classified] locations).
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 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.
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.

3-1 Chapter 3 Maintenance 3.1 Introduction This chapter provides details about the following: l l l l l 3.2 Preventive maintenance (inspection and cleaning) Safe handling of CMOS and LDMOS devices Disassembly and reassembly of the radio Installation of Optional Retrofit Kit Installation of Option Boards Preventive Maintenance The radios do not require a scheduled preventive maintenance program; however, periodic visual inspection and cleaning is recommended. 3.2.
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. 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.
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 l l Avoid accidentally getting solder in the connector.
3-4 3.6 Maintenance Detailed Radio Disassembly 3.6.1 Front Cover from Chassis Disassembly 1. Turn off the radio. 2. Remove the battery: a. Pull down on the two battery-release buttons. b. With the buttons pulled down, the top of the battery will fall from the radio. c. Remove the battery completely from the radio. Battery Release Buttons Battery Figure 3-1: Battery Removal 3. Remove the antenna. 3. Pull the volume and channel selector knobs off their shafts. NOTE: Both knobs slide on and off.
Maintenance 3-5 4. Separate the chassis from the internal electronics front cover assembly as follows: a. Insert a small, 3/16” flat-blade screwdriver, or similar instrument, in between the thin remaining wall and the chassis at the bottom of the radio. Do not mar the O-ring sealing area on the housing. b. Slowly pry the bottom of the chassis from the cover by pushing the 3/16” flat-blade screwdriver down, and rotating the handle of the tool over and behind the base of the radio.
3-6 Maintenance NOTE: At this point, if necessary, the DTMF Retrofit Kit Procedure can be performed. (See section 3.7.7 DTMF Retrofit Kit Procedure (Optional Upgrade Procedure) on page 3-12). 3.6.2 Chassis Assembly/Disassembly 1. If disassembly of the chassis or the main board is required, then use a TORX™ screwdriver with a T6 head to remove the four screws holding the main board to the chassis.
Maintenance 3-7 3. To remove the keypad retainer shield: a. Insert the tip of a “penknife size,” flat blade screwdriver in the opening at the end of the keypad retainer arm tab. b. Pry the tab away from the side of the front cover until it moves past the ledges on the side wall. Repeat this procedure for the four remaining retainer arm tabs. Flat Blade Screwdriver Speaker-Microphone Flex Circuit Tail Keypad Retainer Arm Tabs (4) Retainer Top Hooks Retainer Figure 3-6: Remove Retainer 4.
3-8 Maintenance Retainer Display Module Keypad Option Board Keypad Radio Body Figure 3-5: Removing the Keypad Retainer and Other Boards from the Radio NOTE: At this point, the Option Board Installation Procedure should be performed, if necessary. (See page 3-13) 3.6.4 Speaker, Microphone, and Universal Connector Flex Disassembly 1.
Maintenance 3-9 6. After the universal connector tail of the speaker-microphone assembly is removed, the assembly can be completely removed. If it is necessary to replace the speaker or microphone, or both, do it while the flex circuit is removed from the front cover. When reassembling the microphone in its boot, make sure the microphone port faces the round hole in the bottom of the boot.
3-10 3.7 Maintenance Detailed Radio Reassembly 3.7.1 Control Top Reassembly 1. Replace transmit light pipe and control top seal. 2. Peel off the liners from a new control top escutcheon and place it in the recess in the front cover. Press the control top escutcheon firmly against the adhesive. 3.7.2 PTT Reassembly 1. Put the PTT seal in the PTT bezel. 2. Place the bezel top tab in the top slot inside the front cover PTT opening.
Maintenance 3-11 Catches Retainer Figure 3-8: Lock Retainer Catches to the Radio’s Body 3.7.5 Chassis Assembly Reassembly 1. Slide on the ground contact (if it was removed) on the top corner boss of the chassis. 2. Replace the O-ring. The tabs on the O-ring should reach into the chassis and point down. 3. Stretch the O-ring to place it into the retaining pocket at the bottom end of the chassis. NOTE: When properly assembled, the retainers on the O-ring should align with the slots on the chassis.
3-12 Maintenance 8. Reassemble the knobs, dust cover, antenna, and battery. Radio Chassis Figure 3-9: Fastening the Chassis 3.7.7 DTMF Retrofit Kit Procedure (Optional Upgrade Procedure) If you are performing an upgrade from a basic model to a DTMF model, replace the existing front cover kit with kit number HLN9984 and follow the reassembly steps to reassemble the upgraded radio. (See paragraph 3.7 for details about reassembly.) To activate the retrofit using the radio software, follow these steps: 1.
Maintenance 3-13 NOTE: The CPS may display a warning dialog box when you attempt to write the codeplug back to the radio. It is safe to ignore this warning. Press the OK button. 3.7.8 Option Board Installation 1. With the keypad retainer removed the keypad backer board can be removed without the use of tools. 2. Remove the jumper flex from the connector on the keypad board. Notice the orientation of the flex to the connector.

6-1 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 self-test is not successful, one low-pitched tone is heard. Radios with displays are able to display the error codes.
6-2 Power Up Self-Test 6.2 Error Codes - Privacy Plus At power-up, the radio performs cursory tests to determine 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.
Power Up Self-Test 6.3 6-3 Error Codes - PassPort For the purpose of this document the phrase “PassPort Trunking Controller Board” and its acronym “PTCB” are used.
