Digital Output (Coaxial) Check On the preset menu, set D.OUT to ON.(PMD331/PMD340) Do waveform observation with the oscilloscope, and confirm the digital output level of JT01 to be 0.5Vp-p, square wave within 20% . 1.2. Balanced Output Adjustment (PMD331/PMD340) 1kHz, 0 dB are played back by using TEST disc. Turn RB01 on the rear panel, and adjust the output of JB53 (Balanced Out L-CH). Turn RB02 on the rear panel, and adjust the output of JB54 (Balanced Out R-CH). Adjust each output level to 16 dBu, within 0.5dB. 1.3. Service Mode 1) With power off, simultaneously press the PLAY/PAUSE, MODE and TIME buttons, and at the same time, press the power button. At this time the LCD shows the model name and firmware version. 2) Next, press CUE button. 3) At this time the LCD shows Test : Version . (TEST MODE select menu) 4) The NEXT and PREVIOUS buttons change the TEST MODE(refer to the chart below). The PLAY button selects it. 5) Pressing the CUE button returns to the TEST MODE select menu. 6) Press the STOP button to exit the service mode.
