10. Care and Handling

• Care must be taken to maintain the accuracy of the instrument.
• Do not aim the instrument's telescope directly at the sun.
• When mounting or removing the instrument from the tripod, hold
the instrument with one hand, turn the central screw on the tripod
with the other hand to prevent the instrument from falling. If the
instrument must be carried on the tripod, hold the instrument as
vertically as possible. Never carry the instrument on the tripod in
a horizontal position over your shoulder. Any long distance
transportation should be done with the instrument in its carrying case.
• Put the instrument in its carrying case to avoid possible damage
during transportation.
• After each use, the instrument should be wiped clean and kept in
its carrying case.
• Remove dust from the lenses with a soft brush or a nonabrasive
wipe. Never touch the lenses with your fingers.
• Store the instrument in a dust-free area with low humidity.
• A bag of silica gel dryer is included with each instrument.
• Always remove the batteries when the instrument is not being used
for a long time.
