SECTION II
MAINTENANCE
2.2. GENERAL.
This section describes beacon cleaning, disassem-
bly, O-ring replacement, battery replacement and battery testing.
2.3. BEACON CLEANING.
Clean the switch end of the beacon
with mild detergent then dry thoroughly with a clean cloth.
2.4. BEACON DISASSEMBLY.
Disassembly of the beacon is
limited to battery replacement, as outlined in Section 2.5.
2.5. BATTERY REPLACEMENT AND TESTING.
2.5.1. GENERAL. Perform an operational test (Section 2.1.) to
determine if beacon is operational. If not, insert a new battery and run
the test again (Section 2.1.) Battery replacement should be done in a
maintenance shop under clean conditions to prevent dust from contami-
nating O-ring and lubricant. Because the old O-ring may have devel-
oped a set with age, a replacement is recommended at the time of
battery change. O-ring lubrication should be applied to the new O-ring
and threads before installation.
