3.2 INSPECTION / CLEANING (Continued)
Battery Pack
Inspect the battery pack for dirt, dust, or corrosion. If
necessary, clean the battery contacts with isopropyl alcohol
and a cotton swab. Periodically lubricate the battery pack
o-ring with fluorinated grease. Replace the o-ring if it
becomes cut, nicked, or dried out (see section 3.3).
Objective Lens and Eyepiece
Inspect the objective lens and eyepiece for dirt, grime,
scratches, and cracks. Remove any large particles or loose
dirt using air or a soft cloth. Fine cleaning should be
performed using lens cleaning towelettes. Avoid using
excessive force as this may scratch the lenses.
I/O Jack
Inspect the I/O jack for corrosion, dirt and damage. Gently
remove any large particles of foreign matter and clean the
contacts with a cotton swab dipped in isopropyl alcohol.
