DIAGRAMS
FL DISPLAY/KEY LED TEST MODE
Press the REPEAT, ENTER/NEXT and SURROUND buttons
simultaneously.
1. All FL segments and all LEDs turn on.
2. To access the microprocessor information, press the P FILE
key . Each pressing of the P FILE ke y adv ances the display on
the FL tube in the following sequence.
STR microprocessor version number
HCD microprocessor version number
VCD microprocessor version number (VCD model only)
Model name
Destination
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 counterclockwise 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 v olume
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.
