BATTERY INSTALLATION/REPLACEMENT
A battery strength icon is located at the lower right corner of the display
which indicates the approximate battery capacity. Battery replacement
is necessary when the display icon displays an empty battery silhouette
and flashes a countdown timer in seconds indicating the maximum time
before instrument shut down. This timer begins at 300 seconds and
decreases to 0. During the low power indications the green LED will flash
and a warning beep will be sounded. Prior to shut down the display will
show BAT LOW in the main display.
⚠
WARNING: Always change batteries in a non-hazardous location.
Remove the battery sleeve cover by removing the retaining screw (#10
Torx). Depressing the locking tab on the front of the handle with a coin
or flat object and pull the handle away from the top or display area of the
instrument.
NOTE:
Observe the polarity markings on the inside of the battery holder.
Instrument will not operate with improperly installed batteries.
⚠
WARNING: Never mix batteries of different type or age.
Place three (3) approved batteries into the battery holder. For best results
hold the battery compartment so that it lays in one of your hands. With
your other hand slide the first battery with the negative (-) contact toward
the battery spring. Insert the remaining batteries in the same direction.
The last battery will contact the positive (+) tab at the end of the holder.
If you do not use one of your hands to hold the bottom of the battery
compartment the batteries may come out.
Replace the battery sleeve and allow the locking tab to snap into position.
Replace and secure the retaining screw. Check to be sure the handle is
secure to the instrument body by firmly pulling the handle away.
