TEST MODE
HCD-XG60/XG500
[MC Cold Reset]
• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.
Procedure:
1. Turn the power ON or set to the DEMO mode.
2. Press three buttons of [ /CLOCK SET], [ENTER/NEXT], and
?/1 simultaneously.
3. The set is reset, and displays “COLD RESET”, then becomes
DEMO mode.
[MC Hot Reset]
• This mode resets the set with the preset data kept stored in the
memory. The hot reset mode functions same as if the power
cord is plugged in and out.
Procedure:
1. Turn the power ON or set to the DEMO mode.
2. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],
and [DISC 1] simultaneously.
3. The set is reset, and becomes standby state.
[Change-over the AM Tuning Interval]
(EXCEPT AEP, UK, and Saudi Arabia models)
• The AM tuning interval can be changed over 9 kHz or 10 kHz.
Procedure:
1. Press the ?/1 button to turn the power ON.
2. Select the function “TUNER”, and press the [TUNER/BAND]
button to select the BAND “AM”.
3. Press the ?/1 button to turn the power OFF.
4. Press the [ENTER/NEXT] and ?/1 buttons simultaneously,
and the display on the fluorescent indicator tube changes to
“AM 9 K STEP” or “AM 10 K STEP”, and thus the tuning
interval is changed over.

[CD Delivery Mode]
• This mode moves the optical pick-up to the position durable to
vibration. Use this mode when returning the set to the customer
after repair.
Procedure:
1. Press the ?/1 button to turn the power ON.
2. Press the [LOOP] and ?/1 buttons simultaneously.
3. A message “LOCK” is displayed on the fluorescent indicator
tube, and the CD delivery mode is set.
[LED and Fluorescent Indicator Tube All Lit, Key Check
Mode]
Procedure:
1. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],
and [DISC 2] simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
Press the [DISC 2] button, and the key check mode is activated.
3. In the key check mode, the fluorescent indicator tube displays
“K 0 J0 V0”. Each time a button is pressed, “K” value increases. However , once a button is pressed, it is no longer taken
into account.
“J” value increases like 1, 2, 3 ... if turn the JOG dial clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial counterclockwise.
“V” value increases like 1, 2, 3 ... if turn the [VOLUME] dial
clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial
counterclockwise.
4. To release from this mode, press three buttons in the same
manner as step 1, or disconnect the power cord.

[Aging Mode]
This mode can be used for operation check of tape deck section.
Tape deck section work in parallel.
• If an error occurred:
The aging operation stops and display then status.
• If no error occurs:
The aging operation continues repeatedly.
Procedure:
1. Load the tapes into the decks A and B respectively.
2. Press the [FUNCTION] button to select the function “CD”.
3. Press the [PLAY MODE] b utton to set the “ ALL DISCS” mode,
and press the [REPEAT] button to “REPEAT” off.
4. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],
c
and [DISC 4] simultaneously.
5. The aging mode is activated, if the indicator of disc tray num-
ber on the fluorescent indicator tube is blinking.
6. To release from the aging mode, press the ?/1 button to turn
the power OFF and operate the cold reset. (Refer to the “MC
Cold Reset”)
1. Display at the Aging Mode
• Display operating state of tape deck section alternately.
• If an error occurred, stop display.
2. Tape Deck Section
• The sequence during the aging mode is following as below.
• If an error occurred, stop display that step.
Aging mode sequence (Tape deck section) :
