(a) Battery Installation
1) Rotate battery-box cap counterclockwise to open it. (A coin fits
easily into this slot.)
2) Insert 3 AAA batteries (note polarity) and then rotate battery-box
cap clockwise to close it.
3) When the battery voltage is low, the unit will display a low battery
indicator and there will be a buzzing "reminder" sound every 2-4
seconds. You will still be able to use the instrument for a short
period of time, but should change the battery soon. (Note: When
the low battery indicator is displayed, the illumination function
cannot be used. (See "Using the Illumination Function.)
Note:
a) Remove the batteries when the unit is being stored for a long time.
b) When the low battery indicator is displayed, change the battery soon.
c) Turning off the sound and illumination functions will allow you
to use the unit longer.
