Maintenance

• Always clean the instrument after use.
• Wipe off moisture completely if the instrument gets wet during survey work.
• Never use an abrasive cleaner, ether, thinner, benzene, or other solvents.

Other precautions

• Before starting work or during operation, check that the instrument is function-

ing correctly and performance is normal.

• Protect the instrument from heavy shocks or vibration.
• Always make sure the instrument is completely dry before storing. Dry any

moisture with a soft, clean cloth.

• Remove batteries before storing when the instrument will not be used for peri-

ods on 1 month or more. Batteries may leak fluid when left inside the instru-

ment causing malfunction.

Replacing the dry cell batteries

1

Remove the DB-79B battery holder by turning battery holder knob to “OPEN” side.

2

Install the new 4xD size dry cell batteries (alkaline) referring to the illustration on 
the battery holder.*1), 2), 3)

3

Install the battery holder. Tighten the battery cover knob to “LOCK” side.

*1 Replace all 4 batteries with new ones at the same time. Do not mix used and new 

batteries, and do not mix different types of batteries together.

*2 Use alkaline dry cells.

Nickel hydrogen dry cells and nickel cadmium dry cells can be used too, but the 
operating time is different from the time of alkaline dry cells.

*3 Generally, performances of dry cell deteriorate temporarily in low temperature, but 

recover in normal temperature.

CAUTION

• Perform checks at start of work and periodic checks and

adjustments with the laser beam emitted under normal

conditions. 

• When the instrument is not being used, turn off the power.
• When disposing of the instrument, destroy the battery

connector so that the laser beam cannot be emitted.

• Operate the instrument with due caution to avoid injuries

that may be caused by the laser beam unintentionally

striking a person in the eye. Avoid setting the instrument

at heights at which the path of the laser beam may strike

pedestrians or drivers at head height.
