2. Press three buttons of s (DECK B), A (DISC 1), and S (CD)
simultaneously.
3. On liquid crystal display of the STR-NX1/NX3, the disc calendar blinks, and “ALC OFF” is displayed, then the function
which was set before the test mode became active is displayed.
4. The automatic level control of the tape deck is in OFF status,
but while the
pressed during recording, automatic level control goes in ON
status.
[Tape Deck Test Mode]
(In case of connected to the power feed jig)
Procedure:
1. Turn on the Power switch on the power feed jig.
2. Press three buttons of s (DECK B), A (DISC 1),
and s (CD) simultaneously.
3. The G (CD) and S (CD) LEDs blink, and then pressing G
(CD), G / g (DECK A), or G / g (DECK B) button can
make each play possible.
4. Also, the other functions are enabled by pressing two buttons
simultaneously.
A combination of respective functions and buttons is as follows.

SECTION 4
TEST MODE
[CD Delivery Mode]
• Execute only if connected to the HTC-NX1.
• 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 [ENTER] and ?/1 buttons simultaneously.
3. A message “LOCK” is displayed on the liquid crystal display ,
and the CD delivery mode is set.
[Change-over the MW Tuning Interval]
(EXCEPT AEP and UK models)
• The MW tuning interval can be changed over 9 kHz or 10 kHz.
Procedure:
1. Press the ?/1 button to turn the power ON.
2. Press the [TUNER] button to select the function “TUNER”,
and press the [TUNER BAND] button to select the BAND “MW”.
3. Press the ?/1 button to turn the power OFF.
4. Press the [TUNER MEMORY] and ?/1 buttons simultaneously,
and the display on the liquid crystal display changes to “MW
9 k STEP” or “MW 10 k STEP”, and thus the tuning interval
is changed over.
[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 the [GROOVE] and ?/1 buttons simultaneously.
3. The set is reset, and displays “COLD RESET”, then becomes
DEMO mode.
[Amplifier Test Mode]
Procedure:
1. Press the
2. Press three buttons of [ENTER] , [DISPLAY] , and
?/1 button to turn the power ON.
[TUNER BAND] simultaneously.
3. “ALC OFF” is displayed, then the function which was set be-
fore the test mode became active is displayed.
[LED and Liquid Crystal Display All Lit, Software Version Display, Key Check, VACS Level Display Mode]
Procedure:
1. Press the ?/1 button to turn the power ON.
2. Press three buttons of [ENTER] , [DISPLAY] , and
[STEREO/MONO] simultaneously.
3. LEDs and liquid crystal display are all turned on.
Rotating the JOG dial changes over the check patterns of liquid crystal display.
4. Successively, the following three modes can be activated.
(1) Press the [VIDEO/DVD] button, and the software version is
displayed on the liquid crystal display.
(2) Press the [MD] button, and the key check mode is activated.
In the key check mode, the liquid crystal display 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
