Card Capacity
The number of scenes stored on the card depends on its capacity. Three
types of card are available offering different system capabilities:

outwards and with the 'arrowhead' symbol
pointing towards the slot.
2. After approximately one second, the
display should change to show scene zero.
If the display shows three dashes, this
indicates that the card cannot be read. This
may be caused by an unformatted card, or
if the card's internal battery is discharged
or missing.(Refer to the User Guide).
3. The S

connected to it. This may take up to 30
seconds in a large system, during which
time the display will not change.
4. If the diagnostic flag indicator is lit
(between the first two digits), one or more
diagnostic codes are waiting to be
displayed.
