CLEAR: Default Set
This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with the
[CLEAR]
 key, they cannot be restored after initialization.
So, before clearing, make a note of the adjusted data.
For reference, the drive has been designed so that the gain center
value is 20 and offset value is 80. Other values will be in a range
of 10 to 80. If extreme value such as 00 or FF is set, adjustment
will be faulty. In such a case, check for disc scratch or cable dis-
connection, then perform adjustment again.

6-10. IF  CON  SELF  DIAGNOSTIC  FUNCTION
1. FRONT  BOARD  TEST  MODE
The front board test mode is the IF CON self diagnostic mode.
The IF CON can diagnose the functions of the front panel boards
that the IF CON controls. Normally, the IF CON makes a serial
communication with the SYSTEM CONTROL and operates fol-
lowing thecommands from the SYSTEM CONTROL, but in the
Test mode, the IF CON operates independently from the SYS-
TEM CONTROL.
In the Test mode, the following functions can be checked.
1. Button function
2. Remocon receiving function
3. SYSTEM CONTROL-IF CON serial communication
4. Direct search dial function
5. Click shuttle function
6. Fluorescent display tube lighting check
Grid check
Anode check
7. LED control function
In the Test mode, the set operates same as usual, except voltage
monitoring, communication monitoring, display of fluorescent
display tube, and LED control.
1. The routine that monitors +3.3 V (PCONT) of MB-85 board is
not provided.
2. The monitoring timer for serial communication with the SYS-
TEM CONTROL is not provided. The set is not placed in the
Standby mode, even if the communication with SYSTEM
CONTROL is normal.
3. Display of fluorescent display tube (normally, display is made
following the commands from SYSTEM CONTROL)
4. LED control (normally, control is made following the com-
mands from SYSTEM CONTROL)
2. HOW  TO  ENTER  THE  TEST  MODE
The set must be placed in the Standby mode (red LED lights up).
In the Standby mode, press the 
[SET UP]
 key on the Remocon
while pressing simultaneously the 
[RETRUN]
 button and 
[STOP]
button on the set, so that the set enters the Test mode.
When the Test mode becomes active, the automatic display se-
quence of the FL display tube starts.
1. LEDs and FL display tube all light up for about 5 seconds.
2. Then, the prototypical model name is displayed.
(This model name is a typical name of the series. As the but-
ton arrangement varies depending on the model, make sure
the difference.)

3. Last updating date of the program is displayed.
Example: 981211
4. Following the “GRID TEST” display, odd grids and even grids
are blinking alternately (3 times).
5. Following the “ANODE TEST” display, even anodes and odd
anodes are blinking alternately (3 times). For the FL display
tube type A, even and odd numeric parts of music calendar are
blinking alternately (3 times).
6. All light-up mode restores.
Steps 1 through 6 are repeated. (Refer to “FLD Auto Test Opera-
tion” on page 6-12)
3. HOW  TO  EXIT  FROM  THE  TEST  MODE
Press the 
[POWER]
 buttons on the set and Remocon, and the FL
display tube turns off and the Standby mode is restored where
only the red POWER LED lights up. This is the case where the
SYSTEM CONTROL and IF CON are communicating normally.
To forcibly activate the Standby mode, press the 
[POWER]
 but-
ton together with the 
[STOP]
 button.
