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.

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.
