If the IIC ports have
been checked and found to be incorrect Or not located then [ - -] will appear
in place of [OK] [01] in the line of the [PTCT] means the number of blinks of
the
Power LED is 1. [H09] in the line of the [PTCT] is the error code.
To exit the CAT mode switch off the main power
Power LED is 1. [H09] in the line of the [PTCT] is the error code.
To exit the CAT mode switch off the main power
Note: The line of the
[PTCT] displays when you get into the Selfcheck mode for the first time only
after the Power LED blinks.
