KVT-915DVD,925DVD,935DVD
KVT-945DVD,965DVD TEST MODE
●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 : AV IN1
Each press of the V SEL key in TEST mode should switch
from AV IN1→AV IN2→DVD→TV→NAVI→AV IN1
•Volume : STEP 30
•Switching for Video detector or Test mode main menu (for
FNC key on)
•Writing value for LCD panels touch position adjustment *
• Display position adjustment *
•Serial code writing *
• Microprocessor information
•Information for service menu
•Display for Region code information
•Security code writing (E, W type only)*
You must adjustment for * mark function when you repaired
for IC200 (X14-947 :Video control unit).
● Simple way to clear the security code (without E,W 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 be-
low.
•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 ofTest mode on-screen
Default display is Test mode Main when selected graphic dis-
play mode that in the test mode.
