18-1-2 Removing the slot card

Always switch the AR8200 off when removing a slot card. To access the
socket place the AR8200 on its back and open the front edge of the protective
door. An EJECT slider is mounted on the left hand side of the AR8200 cabinet.
With the AR8200 keypad facing upward slide the EJECT control toward the side
keys of the AR8200, the thumb is best for this purpose... hold the thumb of the
other hand one or two centimetres (one inch) from the bottom of the slot card to
prevent it shooting out of the AR8200 and falling on the floor.
The stiffness of the cards varies and may be tighter when used for the first few
times, the EJECT slider needs quite a push but don't use excessive force or
tools!
