Each panel runs on eight (8) D-cell batteries, which are loaded
positive terminal down
into a removable tube
on the top of each panel, on the side of the panel that is not hinged. Each battery tube is sealed with an
O-ring-sealed, spring-loaded cap, shown in Figure 5.
Figure 5. Battery Tube Cap.
To load/change the batteries:
1)
Press firmly on the cap with your palm and rotate it approximately 1/16 turn counterclockwise. This will
release the entire battery tube.
2)
Rotate the tube as needed to remove it from the panel.
3)
Depress the opposing buttons that hold the cap on the tube, and pull the cap off; see the instruction label
on the tube (Figure 6).
4)
Remove the old batteries (if present). Then, holding the tube close to horizontal, slide the new batteries
into place
positive terminal down
.
CAUTION:
Do not hold the tube vertically and drop the batteries in;
doing so may break the positive contact assembly at the bottom of the tube.
See the instruction label on
the tube.
Figure 6. Remove the Battery Tube Cap and Insert the Batteries in the Correct Orientation.
5)
Reverse the above steps.
Change a panel’s batteries when the voltage drops to <8.5V or after 3 months, whichever comes first.
CAUTION:
Remove the batteries if the instrument will not be used for more than 30 days.
To keep moisture
out of the battery tubes, be sure to change the two O-rings on the cap according to the schedule and
instructions in Section A.2.
