• 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 acciden- tally, 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.
