• For details of each adjustment mode, refer to “5. Electrical Adjustments”.

For details of “ERR DP MODE”, refer to “Self-Diagnosis Function” on page 2.

•If a different mode has been selected by mistake, press the MENU/NO button to exit that mode.

•Modes with (X) in the Mark column are not used for servicing and therefore are not described in detail. If these modes are set accidentally, press the MENU/NO button to exit the mode immediately. Be especially careful not to set the modes with (!) as they will overwrite the non-volatile memory and reset it, and as a result, the unit will not operate normally.
