Storing The Battery; Replacing The Fuses - HP PageWriter 100 User Manual

Note
J
Battery should be removed from unit and placed in
storage if cardiograph will not be used for more than
three months without AC power.
Storing the Battery
To prepare the battery for storage, charge it in
the cardiograph for 16 hours. Then remove it from
cardiograph and store it in a cool, dry location.
Recharge a lead-acid battery in storage for at least 16
hours every six months. This ensures that the battery
does not completely discharge while in storage. The
battery's shelf life is longer with cooler temperatures,
but do not store below freezing level.
Replacing the
Fuses
To replace the AC fuses:
1. Unplug the cardiograph from AC power.
2. Turn the cardiograph bottom-side up.
3. Locate the two AC fuse holders on the bottom of the
cardiograph, as shown in Figure 4-3.
4. Using a screwdriver, turn the fuse cap l/2-turn
counter-clockwise. As the fuse cap is untwisted, it
extends above the surface of the cardiograph case.
5. Pull the fuse cap straight up approximately 2-l/2 cm
(l-inch), until it stops.
6. Remove the fuse. You may need to tap the fuse
holder to shake the fuse out.
7. Insert a new fuse in the holder, slide the fuse cap back
into the case. Fuse must be of the same type and
rating as described on the label located next to the
fuse holders.
8. Tighten the fuse cap l/2-turn clockwise.
