e) Sound function
• If the detector is working in a circumstance that makes it difficult to
use the display function, the sound function can be used instead.
• Press the sound function button. The sound symbol is displayed
which means it is in sound mode.
• When the sound signal has a rapid sound, move the detector
slightly up.
• When the detector has a short sound, move it slightly down.
• When the detector makes a continuous sound, it is level with the
rotating laser beam.
• If there is no sound heard, the detector is not receiving a laser
signal.
(f) Turn-off timer
• The detector will automatically turn off if it has not received laser
signal for 10 minutes
(g) Detector Maintenance
• When you are done using the detector, return it to its carrying case.
• Keep the detector, particularly the detecting window, clean. If
detector becomes dusty, use a clean cloth to gently wipe it clean.
• Avoid knocking the detector over or allowing it to fall on the
ground.
• Although the detector is rain resistant, you should avoid
submerging the unit in water or other liquids. If the detector
comes into contact with water or other liquids, wipe it dry
immediately.
• Do not use detector around fire or expose it to fire in any way.
