Maintenance and Safety
CLEANING: Do not wipe dust or dirt off the detector
reception window or display windows with a dry
cloth or other abrasive material as scratching could
occur, reducing visibility through these windows. A
soft cloth and mild soap and water are effective. The
unit may be submerged or sprayed with a low
pressure water hose if necessary. Do not use any
other fluids other than water or glass cleaner, as
they may attack polymer components.
TRANSPORT: Use the original carton or a laser
instrument case to transport the detector.
STORAGE: If the detector will not be used for a
month or more, remove the batteries.
BATTERIES: It is recommended to use only high
quality alkaline batteries.
INTENDED USES: The laser detector is designed
and suitable for detecting a rotating laser beam.
PROHIBITED USES:
- Operation without instruction.
- Operation other than the intended uses.
- Opening the detector, except the battery door.
- Modification or conversion of the detector.
- Use of accessories from other manufacturers.
PRECAUTIONS:
- The person in charge of the detector must under-
stand the instructions in this manual and ensure
other users do also.
- Periodically carry out test measurements, particularly
after the detector has been subjected to abnormal
