Clearing Cd Mechanism Information And Service Information; Clearing Dc Offset Error Detection Data; Fm/Am Channel Space Switching - Kenwood KDC-MP4032 Service Manual

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.
(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
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
not be retained.)
TEST MODE

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 occurs,
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.
(While "– – – –" is being displayed, power can be ON for 30
minutes.)
2. While in STANDBY source, the current DC offset error con-
dition is displayed.
When detected
When not detected : "DC_OK_ _ _"
3. While error condition is being displayed, press [AUTO] 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.
