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 1/2-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 2-1/2 cm (1-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 1/2-turn clockwise.
