There are three LEDs associated with the function of
the PC card slot. These are:
A green Micro Status LED which will blink steadily
once per second indicating that the microprocessor
is operating and will blink every 0.5 seconds if there
is no software or if it is loading software.
A green (PC) Card Status LED which comes on
when there is a PC card inserted in the slot. This
LED will:
1. Blink every 0.5 seconds when data is being trans-
ferred to, or from, the PC Card. Will be on steady
when the operation is complete indicating the PC
Card may be removed.
2. During Download, the light will blink once per sec-
ond and will blink every 1.5 seconds when the
Download is complete.
A red (PC) Card Fault LED blinks if there is a prob-
lem transferring data from the PC card that has
been plugged into the PC card slot. The red LED
will continue to blink until the PC card is removed.
The LED will also blink if there is an error reading
the card. Check the MessageCenter for description
of error.
