3. While the DC error detection condition is being displayed
as above, press and hold [1] key for 2 seconds to clear
the information about the improper connection and other
detection. Press and hold [2] key for 2 seconds to clear
the information about the number of capacitor leaks.
(E2PROM Clear)
4. DC error display mode is cancelled by resetting. (The last
screen will not be retained.)
(Note) In this mode, the DC error detection display, "Protect"
is not shown.

1. While pressing [SRC] and [AUTO]/[TI] keys, start resetting
to start initializing the following information and NAND
FLASH MEMORY. (While "– – – –" is being displayed,
power can be ON for 30 minutes.)
[CD mechanism information]
• Displays I2C communication condition
• Displays CD mechanism error log
• Displays CD loading error data
• Displays CD ejection error data
• Displays CD time code error count data (missing count).
• Displays CD time code error count data (count not
updated)
[Service Information]
• Displays power ON time is displayed.
• Displays CD operation time.
• Displays number of CD EJECT times.
• Displays number of times panel was opened/closed.
• Displays forced Power OFF data
[DC error detection information]
• DC error detection display 1
• DC error detection display 2
2. During the initialization process, the followings are
displayed.

TEST MODE
3. After the initialization process is completed, the following
is displayed.
When successfully completed
CD_E2P_ _ _ _ :
AUDIO_E2P_ :
NAND_FLASH :
When finished but unsuccessful (Example 1): CD
mechanism information/service information/DC error
detection information initialization NG
CD_E2P_ _ _ _ : ×
AUDIO_E2P_ :
NAND_FLASH :
When finished but unsuccessful (Example 2): Backup/
installer memory initialization NG
CD_E2P_ _ _ _ :
AUDIO_E2P_ : ×
NAND_FLASH :
When finished but unsuccessful (Example 3): Internal
memory initialization NG.
CD_E2P_ _ _ _ :
AUDIO_E2P_ :
NAND_FLASH : ×
When finished but unsuccessful (Example 4): All the
initialization NG
CD_E2P_ _ _ _ : ×
AUDIO_E2P_ : ×
NAND_FLASH : ×
4. In this mode, even if the specifi ed time has passed, the
backup memory items are not written into E2PROM.
5. This mode is cancelled by resetting. (The last screen will
not be retained.)
(Note) In this mode, the DC error detection display, "Protect"
is not shown.
● Frequency span switching (K/M type)
While power is OFF, press and hold [FNC] and [ATT]
keys, and press [SRC] key to power ON.
● Security
• How to enter the forced POWER ON mode
While "– – – –" is being displayed, while simultaneously
pressing [FNC] key and [AUTO]/[TI] keys, press [RESET]
button. With this, it is possible to turn the power on for 30
minutes only.
