a minimum of 10s to
complete the reset.

FACTORY reset function
A factory reset is a 3 step process:
-
Set DIP 15 to ‘on’ and boot the card.
-
Remove power and set the reset switch back to normal position (‘off’)
-
Power up card once again. The operation of the card will immediately reflect the freshly
loaded default settings. However, the card must be kept powered for at least 10
seconds to ensure that these settings are stored locally to be retrieved again at the
next start-up. The cards operational environment must also be kept static during those
10 seconds (i.e. no change in incoming video standard, no commands issued). Failing
to meet this requirement could result in an incomplete reset and require the user to
restart the factory reset sequence.
