last time the generator was used. This check
includes each of the 300 format storage locations.
All user created custom images and test sequences
are also checked. If no problems are found, the
generator goes on to step 3.
If one (or more) items have been corrupted, a
message containing a tally of the defective items
is displayed for 2 seconds. A message for two
corrupted items is shown here. Please note that
the checking routine does not identify the types
of items (format, custom image or test sequence)
that are corrupted. It is up to the user to check
the contents of the individual items. Attempting
to load a corrupted item will report and error
for that item.
❖ A corrupted format can be repaired be ei-
ther editing it or by downloading a new set
of data from a computer.
❖ In most cases, a corrupted custom image or
test sequence can not be repaired. This is due
to the variable data structure used. You will
need to recreate and save the data back into
memory.
❖ Repeated corruption of the data in non-vola-
tile memory usually indicates a weak bat-
tery. Battery replacement information can be
found in the chapter on “Maintenance”.
3. A power-on message, indicating the current firm-
ware and hardware revision levels, will appear
for 2 seconds at the end of the self test proce-
dure.
❖ If an animated image is displayed at power-
on, this message will not disappear until a
button is pushed or a knob is turned.
