DGX-305/DGX-505 TEST No. LCD (initial) Test Functions and Judgment Criteria Output the sine wave by changing the channels in sequence from C2 to G4.[32 notes] Check the sound by hearing that there is not noise or abnormal sound. After auto-scaling is finished, individual keys can be played. (If playing two or more keys simultaneously, the first pressed key has priority to make a sound.) Connect the frequency counter to the [PHONES/OUTPUT] jack.
