(e) Using the Illumination Function
With the detector turned ON, press the illumination switch. This
switch turns the background illumination of the LCD on and off.
(f) Power Saving Function
When the instrument cannot receive the laser signal for 6 continuous
minutes, and there is no detection occurring during this 6 minutes,
the unit will shut off automatically to prolong the battery’s life.
(g) Low Battery Indicator
If the LCD shows a blinking battery sign, it is indicating
that you have low charge on your batteries and that
you need to change them soon (Fig. 21).
If the battery power is too low, the instrument will shut
off automatically. At this time, you must change the
batteries in order to continue using the detector.
5. 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.
