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.
