The 8 channel AP25 may be upgraded to 16 channels by adding the H332 circuit card. Order P/N 9030H33200 latest
version.
H332 Card Installation
Tools required:
Phillips head #2 screw driver
Caution:
The H332 card contains parts that are static sensitive. Use caution when handling to avoid damage.
Keep the card in the anti-static bag until needed. Just before removing the card from the bag, hold the bag and
touch the chassis of the player. This will make your body the same electrical potential as the player (and will
prevent static discharge). It is a good idea to stand on a linoleum or cement floor (not carpet) when handling the
card.
