Special display in Tuner mode
When any of the following messages is displayed in Tuner mode, the F/E may be abnormal. TNE2P NG : The EEPROM is set to the default (unstable values) because the F/E was shipped without passing through the adjustment process, etc. TNCON NG : Communication with the F/E is not possible.

Forced switching of K3I

Each press of the Preset 6 key in Tuner mode should switch K3I from AUTOForced WideForced MiddleForced NarrowAUTO. The initial status is AUTO and the display shows these modes as follows. AUTO : FMA Forced Wide : FMW Forced Middle : FMM Forced Narrow : FMN
Menu-related specifications
A short press of the Q key initiates the menu mode. Pressing the DNPP key on the remote initiates the Menu mode. Continuous holding of a remote control key is inhibited, and workings are short press of any keys. Contrast is adjusted in 3 steps of 0 / 5 / 10 with the Track Up/Down keys (Default value at 5).
AM key Display panel E2PROM condition. (Display) PROM OK (Registered code) PROM NG (Code is write in error) PROM WAIT (Unregistered code) P-ROM NON (Panel security nonfunctional)

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 EjectLast with a short press of the PLAY/PAUSE keys.
Backup current measurement
When the unit is reset while ACC is OFF (i.e. by turning Backup ON), the MUTE terminal goes OFF in 2 seconds in place of 15 second. (The CD mechanism is not activated at this time.)
Other specifications Special display when the display is all on
Pressing the Preset keys while the power is ALL OFF displays the following information.
[PRESET 1] Version display (8 digits, Month/Day/Hour/Minute) (Display) SYS xxxxxxxx : PAN xxxxxxxx : FL model only MEM xxxxxxxx : 4 contrasts FL model only [PRESET 2] Serial number display (8 digits) (Display) SNo xxxxxxxx [PRESET 3] Short press : View power ON time. (The All OFF period is not counted.) 2 seconds long press/hold : Clear power ON time at the power ON time displaying. (Display) PonTim xxxxx [PRESET 4] Max. 60000 (hours)
No displays such as CODE OFF/ON during Power-ON. The LINE MUTE inhibition time is one second from 10 seconds 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 connection on the test mode.

Switching the frequency span (K/M type)
While holding the Preset 1 key and Preset 5 key, reset the unit.
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.
Short press : Display CD operation time. 2 seconds long press/hold : Clear CD operation time at the CD operation time displaying. (Display) CDTim xxxxx Max. 60000 (hours)
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.

[PRESET 5]

Short press : Display CD ejection count. 2 seconds long press/hold : Clear CD ejection count at the CD ejection count displaying. (Display) EjeCnt xxxxx Max. 60000 (times)

[PRESET 6]

Short press : Display Panel open/close count. 2 seconds long press/hold : Clear Panel open/close count at the Panel open/close count. (Display) PnCnt xxxxxx Max. 600000 (times)

FM key

Display ROM collection version. (Display) ROM R xxx Invalid : R
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 possible 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. (Security 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 : Dont enter the panel security set up for new ROM panel. User can not power on the unit.
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 below. 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 entering the numbers.

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 APPROVED 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 because the panel security is clear.
