Each pressing of the P FILE key advances the display on the FL tube in the following sequence. 3. To check the encoder, press the MUSIC key. The following display appears on the FL tube. K0J0V0 The number after K indicates the number of times that the key is pressed. The key which was pressed in the past, is not counted. The key which is pressed hereafter is counted. Pressing any key increases the number after K. The number after J indicates the number of rotations that the JOG dial is rotated. Turning the JOG dial clockwise increases the number after J. Turning the JOG dial counter-clockwise decreases the number after J. The number after V indicates the number of rotations that the VOLUME dial is rotated. Turning the VOLUME dial clockwise increases the number after V. Turning the VOLUME dial counter- clockwise decreases the number after V. To exit this mode, perform the Cold Reset (reset clearing memory) as described below. GENERAL TEST MODE (INCLUDING AMPLIFIER AND TUNER) Press the REPEAT, ENTER/NEXT and CLOCK TIMER SET buttons simultaneously while the main power is on. 1.Sound volume display segment starts blinking. 2.The tuning enters the PRESET mode. 3.Rotating the VOLUME control clockwise increases the volume level to maximum. Rotating the VOLUME control counter-clockwise decreases the volume level to minimum. 4.Pressing the MUSIC key decreases the equalizer curve to minimum and EQ CHECK appears on the display. Pressing the MOVIE key increases the equalizer curve to maximum. Pressing the GAME key makes the equalizer curve flat. 5.Pressing any of the DBFB, GROOVE or SURROUND key disappears EQ CHECK on the display. To exit this mode, perform the Cold Reset (reset clearing memory) as described below. SECTION 2 TEST MODE AGING MODE 1.CD aging mode To execute the CD aging, set the three discs to the CD tray and set the function to CD. REPEAT, ENTER/NEXT and LOOP buttons simultaneously. The CD aging mode starts and the disc calendar starts blinking. 2.Tape aging mode To execute the tape aging, set the two tapes to the tape A and B drives. Set the function to TAPE. Press the REPEAT, ENTER/ NEXT and LOOP buttons simultaneously. Press the A forward key to start the tape aging mode. AGING appears on the display. CD SERVICE MODE Turn on the main power. Press the REPEAT, ENTER/NEXT and KARAOKE PON/MPX buttons simultaneously. VACS toggles between ON and OFF. VACS LEVEL DISPLAY Turn on the main power. Press the EDIT, ENTER/NEXT and KARAOKE PON/MPX buttons simultaneously. VACS level appears on the display. CD SHIP MODE Turn on the main power. Press the PLAY MODE and POWER buttons simultaneously. The main power is turned off and LOCK appears on the display. TUNER STEP CHANGE Turn on the main power. Set the function to TUNER. Select MW band from the present tuning. Turn off the main power. Press the ENTER/NEXT and POWER buttons simultaneously. The main power is turned on and the changed step appears on the display. MD/VIDEO 1 FUNCTION CHANGE Press the FUNCTION and POWER buttons simultaneously while the main power is off. When the function is set to VIDEO 1, the function is changed to MD and MD appears on the display. When the function is set to MD, the function is changed to VIDEO 1 and VIDEO 1 appears on the display. COLD RESET (Reset which clears memory.) Press the REPEAT, ENTER/NEXT and DISPLAY buttons simultaneously at any time. The system is reset while clearing memory. HOT RESET (Reset which does not clear memory.) Press the REPEAT, ENTER/NEXT and TIMER SELECT buttons simultaneously at any time. The system is reset without clearing memory.
