This is only available on Comcard or CWIDKey Basic systems (i.e. 'b'
setting digit 3 = 2.
Compin does not require any Access Code.
Depress the Parameter switch 24 or more times, without holding it
depressed long enough to change any digits, until 'AXXXX' appears on the
display. This number is different for each Compac Card/Key System, which
ensures that the cards/keys for any one system cannot be used on any
other systems.
The access code can be changed by the usual press/hold/release method
using the Parameter switch.
Access Code will only need to be changed to prevent an
existing Card/Key System being used, or to allow a new card system to be
issued in the case of several lost or stolen cards. Refer also to Displaying
and Printing Totals (see page 41)
