Clearing CD mechanism information and
service information (Clearing E2PROM data)
1. While pressing the [Q] key and [ATT] key, reset-start to start
CD mechanism and service information initialization.
[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
2. After the initialization process is completed, the following is
displayed.
Normal termination
: “CD_O_ _ _”
Abnormal termination : “CD_X_ _ _”
3. This mode is cancelled by resetting. (The last screen will
not be retained.)

Clearing DC offset error detection data
(E2PROM data clearing)
If DC voltage difference (DC offset error) is detected be-
tween audio power amplifier (power IC)
±
outputs,
“DC_ERR_ _” is displayed on the display. When this oc-
curs, the audio is forced-mute and the display displays only
“DC_ERR_ _”.
Once this product detected a DC offset error, even if it is
restarted (or reset), its display displays “DC_ERR_ _”.
However, if the error is detected while in Test Mode, it is not
saved in E2PROM.
1. Press and hold [3] and [6] keys and reset-start to go into
the DC offset error display mode.
2. While in STANDBY source, the current DC offset error con-
dition is displayed.
When detected
: “DC_ERR_ _”
When not detected : “DC_OK_ _ _”
3. While error condition is being displayed, press [AUTO] /
[TI] key to clear the detection data. (Clear E2PROM)
4. DC offset error display mode is cancelled by resetting. (The
last screen will not be retained.)
●
FM/AM channel space switching
While power is OFF, press and hold [1] and [5] keys, and
press [SRC] key to power ON.
●
IC10 (X34-) Stereo adjustment (VCO adjustment)
While in test mode and all lights are lit (STANDBY), press
and hold [1] key and press [6] key for 3 seconds or longer.
(Adjusted data will be written on E2PROM.)
