5.2 PREVENTATIVE MAINTENANCE
The procedures listed below for the RAY 210 should be performed at monthly
intervals to minimize the possibility of an equipment failure and assure optimum
performance.
1. Inspect the antenna system. Pay particular attention to the cleanliness of the
antenna connectors and the condition of any soldered connections.
2. Fuse holders and their connections may be subject to corrosion which can
increase circuit resistance. The in-line fuse should be removed from its holder,
inspected and cleaned of any accumulation of dirt or corrosion.
3. The radio front panel should be cleaned with a tissue or a soft non-abrasive
cloth. Care should be exercised when cleaning any plastic surface to prevent
scratching, especially the LCD window area. Mild soap and water may be used
in stubborn cases. The radio case should be cleaned of any salt spray or dust as
often as necessary.
CAUTION Do not use solvents or other chemicals for cleaning this equipment.
NOTE: The following alignment procedures have been provided in this manual
to aid FCC licensed technicians and service personnel only.
5.3 ALIGNMENTS AND SERVICE
The RAY 210 is completely aligned at the factory and normally does not require
any readjustment at installation. However, it is considered good a practice to
verify the power output, modulation, and receiver performance on occasion.
The test equipment listed in paragraph 5.3.1 is used for the test setup shown in
Figure 5-1. This test setup may be used either in part or completely to perform
the following adjustments should any alignments be required.
