(g) Detector Maintenance
• When you are done using the detector, return it to its packing case.
• Keep the instrument, particularly the detecting window, clean. If
unit becomes dusty, use a clean cloth to gently wipe it clean.
• Avoid knocking the unit over or allowing it to fall on the ground.
• Although the instrument is rain resistant, you should avoid
submerging the unit in water or other liquids. If unit comes into
contact with water or other liquids, wipe it dry immediately.
• Do not use unit around fire or expose it to fire in any way.

Level Vial Self-Check
A. X/Y-Direction Level Vial Self-Check
1. Fix the instrument on a platform or a leveling tripod. A tripod
with level vial is preferable.
2. Center the bubbles of X/Y-direction level vials by adjusting the
leveling knob.
3. Turn the instrument by 360° to observe whether those bubbles
are centered at any position, and the instrument is then level.
B. Z-Direction Vial Self-Check
1. Put the instrument with
adjusted X/Y-direction
vials on tripod 3 feet (1m)
from wall A, and level the
setup. Project laser beams
to wall A and wall B respectively, and mark the red laser points
shown on walls as e1 and f1.
