● Panel mechanism
• Auto-panel close inhibition when set-in the CD.
• The panel operation inhibition at power ON/OFF and ACC
ON/OFF.
• The panel position changing Eject→Last with a short press
of the PLAY/PAUSE keys.
● Other specifications
• No displays such as “CODE OFF/ON” during Power-ON.
• The LINE MUTE inhibition time is one second from 10 sec-
onds when start-up the test mode.
• Do not write the security code with the security jig on the
test mode.
• Do not write the serial with the serial writing jig on the test
mode.
• OEM display output is not stop if OEM display not connec-
tion on the test mode.
● Switching the frequency span (K/M type)

unit.
●Check the Flash ROM (KDC-X979, KDC-9026R,
KDC-W9027)
1. Display to the following effect at ALL OFF by assortment
system computer and panel for cover the customization
model attach the panel with no Flash ROM.
• Customization system computer + Flash ROM panel : All
lighting
• Non customization system computer + Non Flash ROM pan-
els : All lighting
• Customization system computer + Non Flash ROM panel :
Panel NG
• Non customization system computer + Flash ROM panel :
Panel NG
2. Output (Hi) to the FLASHROM_CHECK terminal on 102
pin when Flash ROM is function properly.
3. Flash ROM data is initialized when pressing the AM key
long hold at all lighting.
Display is “Data Erase....” in data erasing mode. Do not touch
anything this mode. When the data erase completed, dis-
play is “Erase OK!!”.
If display is “Erase NG!!!!!!”, Flash ROM data unable erase
for some kind or another factors.
When same effect as pressing the AM key long hold and
data erase once again, Flash ROM is defective.

● Demonstration mode
1. How to enter to the Demonstration mode
1. Hold down the [Q] key and [TI (AME)] key button when the
power is on and press the Reset button.
2. This will enter to the Demonstration mode.
2. How to chancel the Demonstration mode
1. Hold-down the Preset [5] key button when the power is on
and press the Reset button.
2. This will cancel the Demonstration mode.
● Security information
1. Forced Power ON mode (All models)
Even when the security (Cord) is approved, resetting the
unit while holding the Q and Preset 4 keys makes it pos-
sible to turn the power ON for 30 minutes.
After 30 minutes have elapsed, it is not possible to return to
the previous condition unless the unit is reset again. (Secu-
rity code is doing not clear at this mode. Put the power on
fill-in.)
When panel security was set up for the unit when it is can
not power on.
In this case, you can use new ROM for the TDF panel that
the unit can be power on for test mode.
Note : Don’t enter the panel security set up for new ROM
panel. User can not power on the unit.
2. Method of registration of the security code after
EEPROM (F/E) replacement (Code security model)
1. Enter the test mode. (See How to enter the test mode)
2. Press the MENU key to enter the Menu mode.
3. When the message “Security” is displayed, press and hold
the Track Up/Down key for 1 second to enter the security
registration mode.
4. Enter the code using the FM/AM/Track Up/Track Down keys.
FM key : Number up
AM key : Number down
Track Up key : Cursor right shift
Track Down key : Cursor left shift
5. Hold down the Track Up key for at least 3 seconds and the
message, “RE-ENTER” appears, so once again enter the
code according to Step 4 above.
6. Press and hold the Track Up key for 3 seconds until “AP-
PROVED” is displayed.
7. Exit from the test mode. (See 2. How to exit from the test
mode)
Note 1 : All Clear is not applicable to the security code of
this model.
Note 2 : When the F/E changed, need re-inscription be-
cause the panel security is clear.
3. How to inscription the panel security code
1. Enter the test mode.
2. Pressing the AM key on all lighting, check the “P-ROM WAIT”
display.
3. The NEXT key is long press 2 seconds, writing the code.
4. Display is “P-ROM OK”.
5. Exit from the test mode.
Note : E2PROM connection is NG when display is “P-ROM
NG”, so detach the panel and rewrite after the display is
“PROM WAIT”. This code can not clear.
4. Simple way to clear the security code (K type only)
1. During code request mode, press the Track UP key for at
least 3 seconds while holding down the AUTO key. (– – – –
will disappear)
2. Enter, “KCAR” with the remote controller as described be-
low.
• Press the remote controller 5 key twice, and press the Track
Up key. (Enters a “K” )
• Press the remote controller 2 key three times, and press
the Track Up key. (Enters a “C” )
• Press the remote controller 2 key once, and press the Track
Up key. (Enters an “A” )
• Press the remote controller 7 key twice, and press the Track
Up key. (Enters an “R” )
3. Security function is canceled and unit sets to All-Off mode.
4. Code request mode appears if a mistake was made in en-
tering the numbers.
