Section 2 MAINTENANCE Introduction This chapter provides details about the following: Preventive maintenance (inspection and cleaning). Safe handling of CMOS and LDMOS devices. Repair procedures and techniques.
Preventive Maintenance Periodic visual inspection and cleaning is recommended. Inspection Check that the external surfaces of the repeater are clean, and that all external controls and switches are functional. 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 4280385A59).
Do not wear nylon clothing while handling CMOS devices. Do not insert or remove CMOS devices with power applied. Check all power supplies used for testing CMOS devices to be certain that there are no voltage transients present.
When damaged parts are replaced, identical parts should be used. If the identical replacement part is not locally available, check the parts list for the proper Motorola part number and order the part from the nearest Motorola Radio Products and Solutions Organization listed in Appendix A of this manual. Repair Procedures and Techniques — General Chip Components Use the RLN4062 Hot-Air Repair Station for chip component replacement. Adjust the temperature control to 370°C (700°F), and adjust the airflow to a minimum setting.
Airflow can vary due to component density. To remove a chip component:. Repair Procedures and Techniques — General Shields Removing and replacing shields is recommended to be done with an Air Blower, BOSCH GHG 600-3 or equivalent.
The temperature should be set to approximately 400°C (752°F). To remove the shield:. Place the circuit board in the circuit board holder. Add solder paste flux around the base of the shield. Repair Procedures and Techniques — General Notes.

Section 1 THEORY OF OPERATION Overview This section provides a detailed theory of operation for the Repeater Indicator Board and its components. Repeater Indicator Board The Repeater Indicator board contains circuitry to drive the front panel indicator LEDs, an RTC battery for the RTC in the transmit radio, as well as an Ethernet controller. Ethernet Interface The power LED is the only LED that is not controlled by the software. This bi-color LED gets turned on green when the 13.8 V output from the power supply is valid. It turns on red when A/C power is lost, and the repeater's backup battery is used.
