➤ Denatured alcohol (use in conjunction with cotton swabs to remove unwanted

deposits of dirt and grease

➤ A pencil with an erase tip in good condition

➤ A small Phillips head screwdriver.

You should also have at your disposal a suitable working area. This area should be

clean and well lit, and as far away as possible from excessive moisture and wind-

blown sand, dirt, rain or salt spray. A dive boat is not a good place change your

NiTe k’s battery.

Replacement procedures—Here are the steps to follow to replace your NiTek’s

battery, using the items described above.

1. Locate the battery compartment access panel on the back of your NiTek (It is the

section that does not hold the wrist strap).

2. Use the Phillips head screwdriver, remove the four bolts holding the panel in

place.

4. Note the condition of the old battery and battery compartment. If you detect

any signs of leakage, such as a build up of corrosion, remove—but do not

replace—the old battery. Instead, take the NiTek to an authorized Dive Rite

dealer for further service.

5. If the old battery appears in good condition, carefully remove and dispose of

it properly.

6. Clean the new battery’s contacts using the pencil eraser. If you detect any build

up of dirt or grease in the area where the compartment door O-ring makes

contact, remove it using a cotton swab soaked in a small amount of denatured

alcohol.

7. Remove the O-ring from the its slot. Be careful not to damage it. Do not use any

sharp objects to pry the O-ring out.

8. Install the new battery in the exact same position as the old one occupied. The

negative side of the battery should face the inside of the computer; the positive

side should face the battery compartment door.

9. Use a clean paper towel or wipe to remove any dirt or excess grease from the

O-ring. Inspect the O-ring carefully for any signs of nicks, cracks, ﬂ at spots or

deformities. If necessary, obtain a replacement O-ring from an authorized Dive

Rite dealer.

10. The O-ring should have a smooth, shiny appearance. If it appears dry, apply a

very light coating of silicone grease.
