2.1.3 Battery Installation

Note: Three “AA” alkaline batteries must be installed in the unit

before the monitor will operate. The unit must be recalibrated whenever new batteries are installed and the HI and LOW alarm set points must be reset to the desired values

To install the batteries:

1.Turn the unit off (if it is on).

2.Hold the instrument face down in the palm of your hand. Use a coin to pry up the latch that secures the battery compartment door. Remove the battery compartment door.

CAUTION: IMPROPER INSTALLATION OF THE BATTERIES MAY RESULT IN DAMAGE TO THE UNIT AND BATTERIES.

Note: Use alkaline batteries only. Other battery types will produce erroneous battery test readings.

3.Install 3 “AA” alkaline batteries into the holder as shown in Figure 2-6. Each battery has its own slot. To insure proper polarity, place the bottom (flat) or negative end of the battery in the end of the holder marked “–”. Place the top (button) or positive end of the battery in the end of the holder marked “+”. Do this for each battery.
