TEST MODE
DDX7015/7025/7035
DDX7045/7065
● How to enter the test mode
While pressing and holding the Eject key and SRC key, reset
the unit.
● How to exit from the test mode
While holding the Reset key, reset the unit.
Note : Turning ACC off, power off, momentary powers down
are does not exit for the test mode.
● Test mode operation
• Source selector : VIDEO
Each press of the V SEL key in TEST mode should switch
from VIDEO→NAVIGATION→DVD→VIDEO
•Volume : STEP 30
• Switching for Video detector or Test mode main menu (for
FNC key on)
• Microprocessor information
• Information for service menu / Serial code writing *
• Chroma adjustment *
•Writing value for LCD panels touch position adjustment *
•Panel mechanism position adjustment *
• Display position adjustment *
• Security code writing (E,M,X,C type only) *
You must adjustment for * mark function when you repaired
for IC200 (X14-939 : Video control unit).
● Simple way to clear the security code (without E,M,X,C type)
1)How to enter the security code entry
While pressing the Reset key when unit is security on mode.
2)Enter, “KCAR” with the remote controller as described below.
• Press the remote controller 5 key twice. (Enters a “K”)
• Press the remote controller 2 key three times. (Enters a
“C”)
•Press the remote controller 2 key once. (Enters an “A”)
• Press the remote controller 7 key twice. (Enters an “R”)
Code request mode appears if a mistake was made in entering the numbers.
3)Security function is canceled and unit sets to Menu display
mode.
● Specification of test mode on-screen
