PROCEDURE FOR CHECKING/CLEARING SERVICE COUNTS OF MICROWAVE OVEN

The following procedure enables the servicer to obtain the total service counts (cook cycles) for memory cooking, double quantity cooking and defrost. The maximum capacity of the counter is 999,999 counts, above which the counter will reset to "0". The counter will retain the total counts (will not clear) in the event of a power disruption.

1)Practice for checking total service counts (eg; 234,567 Counts).
