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 manufacturing location. Modifications can only be made by the original product manufacturer (Motorola) at one of its FM audited manufacturing facilities.
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”).
Intrinsically Safe Radio Information 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.

Intrinsically Safe Radio Information Notes...
In instances where the product is covered under a “return for replacement” or “return for repair” warranty, a check of the product should be performed prior to shipping the unit back to Motorola. This is to ensure that the product has been correctly programmed or has not been subjected to damage outside the terms of the warranty.
Technical Services (MTS). If no part number is assigned, the part is not normally available from Motorola. If the part number is appended with an asterisk, the part is serviceable by Motorola Depot only. If a parts list is not included, this generally means that no user-serviceable parts are available for that kit or assembly.
Introduction: Radio Model Chart and Specification Radio Model Chart and Specification The radio model charts and specifications are located in the Basic Service Manual listed under the Related Documents paragraph of this chapter. Radio Model Information The model number and serial number are located on a label attached to the back of your radio.

The microprocessor then samples the analog to digital voltages at the keypad row and keypad column, then makes a comparison with a map table to identify the key pressed.

Maintenance: General Repair Procedures and Techniques To remove a chip component: 1. Use a hot-air hand piece and position the nozzle of the hand piece approximately 1/8” (0.3 cm) above the component to be removed. 2. Begin applying the hot air. Once the solder reflows, remove the component using a pair of tweezers.
8. Remove the circuit board and inspect the repair. No cleaning should be necessary. Recommended Test Tools Table 8-1 lists the recommended tools used for maintaining this family of radios. These tools are also available from Motorola. Table 8-1. Recommended Test Tools Motorola Part Description...
Maintenance: Replacing the Circuit Board Fuse Replacing the Circuit Board Fuse In cases where the radio fails to turn on when power is applied, the circuit board fuse should always be checked as a probable cause of the failure. The radio must be disassembled to replace the fuses as described in the Basic Service Manual (see section Table 1-1.
2. Lift the circuit board out of the radio chassis, then remove and discard the thermal pad located between the circuit board and chassis. 3. After repairs, replace the thermal pad (Motorola P/N 7580556Z01) then reinstall the circuit board into the radio chassis.
Maintenance: Power Up Self-Test Error Codes Power Up Self-Test Error Codes 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 high- pitched self-test pass tones.
