TB 11-5820-890-12

Latch Snap. To replace a broken cover latch, use the following procedure. Refer to Figure 4-1, and "Insert B" of the

figure for part location.

STEP 1

Using a flat tip screwdriver carefully press on the retaining lip of the latch (1).

STEP 2

Move the screwdriver to push the latch out of the retainer and lift the latch off the housing assembly.

STEP 3

Push a new latch into the retainer and press down until the latch snaps into position.

STEP 4

Close the top and latch it; if the latch is properly seated, the latch will lock the top; if not, the latch will

pop out of the retainer.

Battery Cover(s). To replace the battery cover use the following procedures for replacement. See Figure 4-2 for part

location.

STEP 1

Loosen the four captive screws on the cover (2) and lift the assembly off the housing.

NOTE

The battery cover is keyed to hold the battery pack in the proper position for good electrical contact and

can only be installed one way by inserting the positive battery contact first into the housing.

STEP 2

Install the replacement assembly over the battery opening and tighten the four captive screws.

Housing Battery Contacts. The battery contacts are unique to the polarity of voltage applied; that is, the positive

contact is different in appearance from the negative contact. Both contacts use the same attaching hardware, so the

replacement procedure is the same for both contacts as described below refer to Figure 4-2 for location of parts.

STEP 1

Remove the battery cover (3) and battery holder (2).

STEP 2

Using a 1/16 inch hex driver, remove the screw (1) from the defective contact (4 of 5).

STEP 3

Carefully remove the defective contact (4 or 5) from the ANCD battery cavity.

STEP 4

Place the new contact into position.

STEP 5

Install the hex-screw (1) into the contact and tighten the screw carefully.

NOTE

Do not over tighten the screws (1) as damage will occur to the housing and the ANCD will

have to be replaced.

Keypad. The ANCD uses two keypads, full function and limited function. They are both replaced in the same fashion.

The following is a description of the replacement procedure; refer to Figure 4-3.
