4. Sleep test
• Pressing the x
•B key causes the set to enter the sleep state.
• When the HOLD switch is ON, the LCD is turned off. When
OFF, the LCD is turned on.
• Press any keys to exit the sleep state.
5. Beep test
• Beep sound of 1.3 kHz or 2 kHz is output.
6. SIO test
• Perform the connection test of the RTC, EEPROM and serial to
parallel conversion IC.
• As to the test result, if all of the connection test are OK,
“****OK****” is displayed. If the connection test of the RTC is
NG, “**RTCNG**” is displayed. If the EEPROM is NG,
“**EEPNG**” is displayed.
7. Key entry test
• When the any key is pressed, the entry key and the A/D converted
value (hexadecimal) of the two channel keys are displayed.
• When the  STOP  key is pressed, the A/D value of the key is
displayed while the key is depressed. When the key is released,
the screen returns to the test menu.
8. Battery remaining power test
• The detected A/D value (hexadecimal) of the battery remaining
power is displayed.
9. LED/EL test
• LED (red and green) and EL are all turned on.

10. USB test
• When the menu starts the USB self-check, either presence or
absence of the Vbus is judged.
(Vbus is present: “VBUS: ON”, Vbus is absent: “VBUS: OFF”)
• The USB driver always works regardless of presence or absence
of the USB signal only when Vbus is available during the USB
test. At this time, turning on  HOLD  causes the set to move to the
suspend state. Turning off the Vbus causes the set to return to the
test menu.
11. DC-IN test
LCD : Detection result of external DC power supply is display is
displayed of LCD.
12. DATA READ test (not used)
Not use for test command design check or verification.
13. Rest menu
• Pressing the  x
•B    key causes the set to enter the menu
initialization standby state.
• When the following keys are all entered and the  x
•B  key is
pressed, the initialization is executed. At the same time, the
WakeUp signal is checked, too.
Check keys: VOLUME+ , VOLUME– , A-B REPEAT ,
INDEX , STOP , zREC , ERASE , . ,
x•B , > , MENU , FOLDER
and check states of Memory Stick insert and
outsert ( EJECT ).
• If all tests end in success, “**ALLOK**” is displayed. If the key
entry is NG or if any of the keys is not pressed yet, “**KEYNG**”
appears. If saving in the EEPROM is NG, “**MENUNG**”
appears.

Replacement of IC6201, IC7102 used in this set requires
a special tool.
The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
from that of conventional IC.
Note on Printed Wiring Boards:
• Y
