Installing the AXC-232++ in a CardFrame:

1. Remove all static electricity by grounding yourself.
2. Hold the card by the tab end and slide the card into the frame, into one of the slots. Make sure
the card is correctly positioned in the guide slot.
3. Gently push the card in until it is firmly seated in the card connector slot. You do not have to
disconnect the power to the CardFrame when you install the card. When power is applied to
the card, the LEDs blink to indicate the connection.
