5. MAInTEnAnCE PROCEDURES
The Spear should always be stored in the supplied packaging, particularly in heated and ventilated
rooms. To keep the device operational, please follow the instructions (below) regarding preparations
preparations for storage. The battery should be stored separately from the device, and be inserted into
the battery compartment only when the device is being prepared for use. The presence of both acids
and alkalis near the device is not recommended.
While stored, your Spear should be protected from exposure to direct sunlight or extreme tempera-
tures.
SPEAR ClEAnIng PROCEDURES
1) Gently remove any dirt from the sight’s body using a clean, soft cloth.
2) Wipe external surfaces down (with the exception of optical surfaces) with a clean cloth that has
been moistened with pure water.
3) Dry all wet surfaces with a different clean, dry cloth.
4) Carefully remove any dirt from the optical surfaces using a lens brush.
5) To avoid scratches, optical surfaces must be cleaned using a clean cotton swab that has been slight-
ly dampened with pure alcohol. The glass should be wiped in circular motions starting from the center
and moving out towards the edge, without touching the barrel. Change the cotton swab as soon as it
becomes dirty.
CAUTIOn:
Only apply photographic lens cleaning tissues to the optical surfaces. Avoid damaging or leaving
fingerprints on the lenses. A can of compressed air may be used to blow dust off of the lenses. Do
not tip the can while spraying, as you may cause the propellant to freeze as it exits the can. This
may damage the glass.
