(g) Low Battery Indicator
If the LCD shows a blinking battery sign, it is indicat-
ing 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.
