played during step 1 above (Resetting
potentiometer input signal)

shown in step 1 above, if the potentiometer
input signal (voltage) is out of the range in
the following table, an error code is dis-
played during the resetting operation and
resetting cannot be completed.

If an error code is displayed during the resetting
operation and the starting switch is turned to
the OFF position with the error code left dis-
played and the starting switch is turned to the

signal is deleted.
Accordingly, remove the all factors of the error
code, then reset securely.
