Installing the Apricot LS Security Card
The Security Card is normally pre-installed at the factory. You
should not need to install the card except in very unusual
circumstances.
The card is intended to be fitted in an Apricot computer that has an
infrared sensor and an Apricot BIOS with LOC Technology v2.1
extensions.
