4. Clear the status counter
After repairing the matter which caused the error [C 410], perform the following:
(1) Turn ON the power while [0] and [8] are pressed  simultaneously.
(2) Key in “400”, then press [START]. 
(3) Change the current status counter value “1” or “ 2” to “0”, then press [ENTER] or [INTERRUPT] 
(to cancel [C410]).
(4) Turn the power OFF and then back ON. Make sure t hat the equipment enters the normal ready 
state.
