Chapter 7 Disassembly/Reassembly Procedures

This chapter provides detailed procedures for disassembling/reassembling SSE 5000 radios and also includes preventive maintenance and handling precautions, which provide information vital to the successful operation and maintenance of your radio.

When performing the disassembly/reassembly procedures, refer to the exploded view (Figure 7-1 on page 7-3) and to the parts list (Table 7-1 on page 7-4). Items in parentheses ( ) throughout this chapter refer to item numbers in the exploded view and its associated parts list.

This chapter also has procedures for removing and installing the SSE 5000 radio’s standard accessories and changing the Volume and Channel Select knobs.

7.1General Maintenance

In order to avoid operating outside the limits set by the FCC, we recommend that you align the SSE 5000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first. Periodic visual inspection and cleaning is also recommended.

7.1.1Inspection

Check that the external surfaces of the radio are clean, and that all external controls and switches are functional. A detailed inspection of the interior electronic circuitry is not needed.

7.1.2Cleaning

The following procedures describe the recommended cleaning agents and the methods to be used when cleaning the external surfaces of the radio. External surfaces include the housing assembly and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime.

The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild dishwashing detergent in water.

!	The effects of certain chemicals and their vapors can have harmful results
	on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals
C a u t i o n	should be avoided.

The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be used to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.
