2. Precautions
Using the Instrument
• The SDL30/50 is a precision instrument. Avoid severe shocks or
vibration.
• Be careful when removing the instrument from its case.
• Do not place the SDL30/50 directly on the ground.
• When the operator leaves the SDL30/50, the vinyl cover should be
placed on the instrument.
• Never carry the SDL30/50 on the tripod to another site.
• Always turn the instrument off and remove the battery before
storing the instrument in its case.
• When the instrument is placed in the carrying case, see "20.1
Standard Equipment".
• Always wipe off moisture and dirt adhering to the instrument during
survey work. Moisture or dirt on the lens may result in incorrect
readings.
• Consult your local dealer before using the instrument under special
conditions such as long periods of continuous use or high levels of
humidity. In general, special conditions are treated as being outside
the scope of the product warranty.
Maintenance
• Always clean the instrument before returning it to the case. The
lens requires special care. Dust it off with the lens brush first, to
remove tiny particles. Then, after providing a little condensation by
breathing on the lens, wipe it with the supplied cleaning cloth or
lens tissue.
• 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
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 instrument and accessories in a dry room where the
temperature remains fairly constant.
• If any trouble is found with the screws or optical parts (e.g. lens),
contact your local dealer.
