(Fig. 3) for the removal technique. NOTE: Power Supply & Ringer cards have a lower hole
only, i.e. only one puller to be used on this card.
Figure 4 - Card removal technique
IMPORTANT:
All cards, except the Power Supply & Ringer Card, have an upper and lower
hole at the front allowing both pullers to be used. The Power Supply & Ringer card has a
lower hole only and the single puller must be angled to be central - providing an even
removal force. Each card is polarised. Ensure that cards are inserted in the correct slot.
Forcing a card into the wrong slot may result in damage to the connector pins.

Factory set for 50V operation. Item 13 is located on the motherboard, to the right hand side
of the Power Supply and Ringer Card.
