cancel accenta optima 5 minute service beep?

press prog then engineer code 9999 default.
then press 7 to get into timers and counters menu.
then press 3 for service timer menu.
press 0 to turn off all service timers (this is usually set by default).
if you dont have engineer code you will have to reset panel to default values and go from there.
