2. PRECAUTIONS
• When placing the SET in its case, first remove its battery and place it in the case
in accordance with the layout plan.
Maintenance
• Always clean the instrument before returning it to the case. The lens requires
special care. First, dust it off with the lens brush to remove tiny particles. Then,
after providing a little condensation by breathing on the lens, wipe it with the
wiping cloth.
• If the display is dirty, carefully wipe it with a soft, dry cloth. To clean other parts
of the instrument or the carrying case, lightly moisten a soft cloth in a mild
detergent solution. Wring out excess water until the cloth is slightly damp, then
carefully wipe the surface of the unit. Do not use any organic solvents or
alkaline cleaning solutions.
• Store the SET in a dry room where the temperature remains fairly constant.
• Check the tripod for loose fit and loose screws.
• If any trouble is found on the rotatable portion, screws or optical parts (e.g.
lens), contact your SOKKIA agent.
• When the instrument is not used for a long time, check it at least once every 3
months.
"26. CHECKS AND ADJUSTMENTS"
• When removing the SET from the carrying case, never pull it out by force. The
empty carrying case should be closed to protect it from moisture.
• Check the SET for proper adjustment periodically to maintain the instrument
accuracy.
