SAFETY INSTRUCTIONS
• You must confirm that the batteries powering the HHM-NCV40
are not weak or dead before you use the unit to test for the
presence of AC voltage. It is essential that you do this
each time you use the instrument.
The usual way to check the batteries is to insert the blade
tip (Fig. 1, Callout 1) into both slots of a 110VAC outlet
known to be energized with the HHM-NCV40 sensitivity set
to maximum. If the beeper does not sound and the LED does
not light for either slot, replace both "AAA" batteries before
proceeding. Another simple way to check for live batteries
is to briskly rub the tip of the unit through your hair with
sensitivity maximized; static electricity has more than
enough voltage to activate the beeper and LED.
• Remember to move the power switch of the HHM-NCV40 to
the OFF position after you have finished using the unit. This
is safety instruction because leaving the instrument powered
