SECTION 3
TEST MODE
[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 [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]
• 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] 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
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.
(3) Press the [TAPE] button, and the VACS level is displayed on
the liquid crystal display.
5. To release from these mode, press three buttons in the same
manner as step 2, or remove the power cord.
[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
[ENTER] , [DISPLAY] , and
[TUNER MEMORY] simultaneously.
3. The set is reset, and becomes standby state.
