Care and Use of MAM Kits

(1)

Each kit consists of certain printed circuit cards and memory stacks that suffer

high casualty rates. These kits are subdivided into a "Fixed Kit" and a "Variable

Kit". The Fixed Kit contains cards which are common to all single bay AN/UYK-

7s. The Variable Kit contains circuit cards which are peculiar to AN/UYK-7s

used with the Mk 92 Mod 1 Fire Control System (FCS).

The kits were delivered with a listing of the cards showing their arrangement in

the storage boxes. This is the definitive list for the MAM Kit. Part III, Section CF-

OSI of the cutter's COSAL Manual also contains a list of the MAM cards.

Stowage. The kits were shipped in two electrostaticproof boxes which shall also serve

as storage boxes for the kits. The kits shall be stored in a workspace. The kits shall not

be stored in the cutter's storeroom under individual circuit card stock numbers.

Although only a few of the circuit cards are electrostatically sensitive, handling of all

the cards should be kept to a minimum and the individual cards should be kept wrapped

in the original foil wrapper.

Use. If computer diagnostics indicate a particular card is suspect, the appropriate MAM

card should be installed in place of the suspect card. If the problem is corrected, the

MAM card is to be removed and a replacement card drawn from the storeroom installed.

If the problem is not corrected, the MAM card is to be removed and the original card

reinstalled. If a storeroom spare is not available to replace a defective card, the MAM

card may be used as a temporary repair if operational requirements dictate. A

replacement card must be requisitioned immediately to replenish the MAM kit.
