8. HANDLING PRECAUTIONS

• Use care to avoid shock to the instrument. Always provide some cushioning to
minimize risk of shock during transportation. The instrument cannot be expected to
function properly if exposed to heavy shock.
• Check the battery indicator. Be sure to check the voltage level before using
the instrument.
• Carrying the instrument. Always remove the instrument from the tripod when
carrying at the job site. If the instrument must be carried on the tripod, hold the
instrument as vertically as possible and keep it in front of you. Never carry the
instrument horizontally over your shoulder. Any long distance transport should be
done with the instrument in the carrying case.
• Do not expose the instrument to direct sunlight for long periods. Never
leave the instrument exposed to extreme heat longer than necessary. It could affect
the instrument's performance.
• Store the instrument properly. The instrument should be stored in an area of
low humidity and where the temperature will not exceed 110° F (45° C). Always
remove the batteries before storing the instrument.
• Cleaning the instrument. Any dust on the lenses should be removed first with a
small brush, then use a lens tissue or soft clean cloth (use a light touch to avoid
scratching the lenses).
Dry the instrument after use in the rain. Do not use harsh chemicals to clean the
instrument or carrying case. A mild detergent or water dampened rag is all that is
necessary.
