TEST MODE  
● Security information  
3. How to inscription the panel security code  
1. Enter the test mode.  
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.  
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”.  
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.)  
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.  
When panel security was set up for the unit when it is can  
not power on.  
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)  
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. Enter, “KCAR” with the remote controller as described be-  
low.  
2. Method of registration of the security code after  
• Press the remote controller 5 key twice, and press the Track  
Up key. (Enters a “K” )  
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.  
• 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” )  
4. Enter the code using the FM/AM/Track Up/Track Down keys.  
FM key : Number up  
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.  
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.
