• When started in Test Mode, duration of prohibiting LINE
MUTE shall be changed from 10 seconds to 1 second.
• While in Test Mode, serial number is not written with a se-
rial-number-writing jig.
• When in Test Mode, when DC offset error detection is run,
the detection information is not written into the E2PROM.
• DEMO mode shall not be operated while in Test Mode, CD
Mechanism Error Log Data Clearing Mode, or DC Offset
Error Detection Data Clearing Mode.
Also, do not display DEMO ON/OFF option items in the

CD mechanism and service information initialization.
(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 forced Power OFF data
2. After the initialization process is completed, the following is
displayed.
When successfully completed: “CD_O_ _ _ _”
When finished but unsuccessful: “CD_X_ _ _ _”
3. This mode is cancelled by resetting. (The last screen will
