MAINTENANCE AND TROUBLESHOOTING
3.1 MAINTENANCE PROCEDURES
The operator should inspect the CNVD-T3 before each use
and after it has been in extreme conditions, such as
prolonged exposure to intense temperatures. The following
procedures will prolong the life of the CNVD-T3 and help
ensure safe operation.
3.1.1 Batteries
. Inspect the batteries for cracks, dents,
leakage, or bulging. If a battery shows signs of damage,
remove and dispose of properly. Replace batteries as
required per paragraph 2.2.2.
3.1.2 Battery Compartment . Inspect the battery
compartment for dirt, dust, or corrosion. Dirt or debris that
cannot be shaken loose from the battery compartment may
be removed using a cotton swab. If necessary, clean battery
contacts with a cotton swab and isopropyl alcohol.
Periodically lubricate the battery compartment o-ring with
fluorinated grease. Replace the o-ring if it becomes cut,
nicked, or dried out.
3.1.3 Objective Lens and Eyepiece . Inspect the objective
lens and eyepiece for dirt, dust, and grime. Remove any
large particles or loose dirt using the lens pen retractable
brush. Fine cleaning of the optical surfaces should be
performed using the lens pen cleaning tip. Avoid using
excessive force as this may scratch the lenses.
