How to exit from the test modeWhile holding the Preset 6 key, reset the unit.(Note) The test mode cannot be terminated by ACC OFF,power OFF or momentary power down.3. Initial status in the test mode• Sources : ALL OFF• Display : All segments are lit.• Volume : -10 dB (displayed as " 30 ")• Loudness : OFF• CRSC : OFF regardless of the presence ofswitching function.• SYSTEM Q : Flat4. Special display in Tuner modeWhen any of the following messages is displayed in Tunermode, the F/E may be abnormal.• " TNE2P NG ": The EEPROM is set to the default(unstable values) because the F/E was shipped withoutpassing through the adjustment process, etc.• " TNCON NG ": Communication with the F/E is notpossible.5. Forced switching of K3IEach press of the Preset 6 key in Tuner mode should switchK3I from AUTO → Forced Wide → Forced Middle → ForcedNarrow → AUTO.The initial status is AUTO and the display shows thesemodes as follows.• AUTO : FMA• Forced Wide : FMW• Forced Middle : FMM• Forced Narrow : FMN6. Test mode specifications of the CD receiver• Forced ejection is inhibited in the reset start operation.When the unit is reset while a CD is loaded in it, the CDis not recognized by resetting.• Each press of the Track Up key jumps to the followingtrack numbers:No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13→ No. 14 → No. 9 (The cycle restarts from here.)• Each press of the Track Down key jumps to the previoustrack number to the track being played.7. Audio-related specifications• A short press of the Q key initiates the audio adjustmentmode.• Pressing the ∗ key on the remote initiates the audioadjustment mode.• Continuous holding of a remote control key is inhibited.• Bass, Middle and Treble are adjusted in 3 steps of Min /Center / Max with the Track Up/Down keys.• Balance is adjusted in 3 steps of Left Max / Center / RightMax with the Track Up/Down keys.• Fader is adjusted in 3 steps of Rear Max / Center / FrontMax with the Track Up/Down keys.• HPF is adjusted in 2 steps of Through/220Hz with theTrack Up/Down keys.• LPF is adjusted in 2 steps of Through/120Hz with theTrack Up/Down keys.• Bass f, Bass Q, Bass EXT, Middle f, Middle Q and Treblef are not dealt with by the audio adjustment.8. Menu-related specifications• A short press of the CLK key initiates the Menu mode.• Pressing the DNPP/SBF key on the remote initiates theMenu mode.• Continuous holding of a remote control key is inhibited.• Contrast is adjusted in 3 steps of 0/5/10 and the default is 5.9. Backup current measurementWhen the unit is reset while ACC is OFF (i.e. by turningBackup ON), the MUTE terminal goes OFF in 2 seconds inplace of 15 second. (The panel and CD mechanism are notactivated at this time.)10. Special display when the display is all onPressing the Preset keys while the power is ALL OFFdisplays the following information.[PRESET 1] Version display (8 digits, Month/Day/Hour/Minute)(Display) SYS xxxxxxxx System microcomputer[PRESET 2] Serial No. display (8 digits)(Note) CD/RK type eXcelon model(Display) S. No. xxxxxxxx[PRESET 3] Short press : View power ON time. (The AllOFF period is not counted.)Long press/hold : Clear power ON time.(Display) PonTim xxxxx Max. 65535 (hours)[PRESET 4] Short press : Display CD operation time.Long press/hold : Clear CD operation time(Display) CDTime xxxxx Max. 65535 (hours)[PRESET 5] Short press : Display CD ejection count.Long press/hold : Clear CD ejection count.(Display) EjeTim xxxxx Max. 65535 (times)[PRESET 6] Short press : Display Panel open/close count.Long press/hold : Clear Panel open/close count.(Display) PnCnt xxxxx Max. 655350 (times)11. Other specifications• Automatic panel closing when a CD is inserted is inhibited.(M&T model)• Panel operation by turning power OFF/ON is inhibited.(M&T model)• Messages such as "CODE OFF" are not displayed whenpower is turned ON.• Pressing the ATT key opens or closes the panel. (M&Tmodel)• Pressing the TI (AUTO) key during changer operationturns 2zone ON. 2zone can be turned OFF by pressingthe TI (AUTO) key again. The P/S dot lights while 2zoneis ON.• Pressing and holding the CLK key for a second in theALL OFF status the Mask Key (security) write mode.tongueTurn 2 times.End of Roller ass’yFPCSecurity-related information1. Forced Power ON mode (All models)Even when the security (Mask key) is approved, resettingthe unit while holding the ATT and Preset 4 keys makes itpossible to turn the power ON for 30 minutes.After 30 minutes have elapsed, it is not possible to returnto the previous condition unless the unit is reset again.2. Method of registration of the security code afterEEPROM (Tuner Unit Ass'y) replacement (Codesecurity model)1. Enter the test mode. (See 1. How to enter the test mode)2. Press the CLK key to enter the security registration mode.3. Enter the code using the Preset 1/2/3/4 keys.Example: To enter " 3510 "• Press the Preset 1 key 4 times.• Press the Preset 2 key 6 times.• Press the Preset 3 key twice.• Press the Preset 4 key once.4. Hold down the DISP key for at least 3 seconds and themessage, " RE-ENTER " appears, so once again enterthe code according to Step 3 above.5. Press and hold the DISP key for 3 seconds until" APPROVED " is displayed.6. Exit from the test mode. (See 2. How to exit from the testmode)(Note) All Clear is not applicable to the security code ofthis model.3. Simplified method of clearing the security code(K Type only)1. While the code entry is requested, press and hold theVOL UP key for 3 seconds while holding the DISP keypressed. (This should turn "----" off.)2. Enter " KCAR " from the remote. (Same way as the 00model)• Press the 5 key on the remote twice, then press theTrack Up key. (This enters " K ".)• Press the 2 key on the remote 3 times, then press theTrack Up key. (This enters " C ".)• Press the 2 key on the remote once, then press theTrack Up key. (This enters " A ".)• Press the 7 key on the remote twice, then press theTrack Up key. (This enters " R ".)3. The security code is cleared and the unit enters the ALLOFF mode.4. If you commit a mistake in the code entry, the unit entersthe code request mode again.4. Method of writing the Mask key while the EEPROMis in the initial status1. Enter the test mode. (See 1. How to enter the test mode)2. Press the CLK key to enter the Mask key registrationmode. " TRANSMIT1 " should be displayed now. Thedisplay at this time should show " < > " in place of " [ ] ".3. Point the Mask key remote toward the light sensor, andpress and hold its key for more than 0.5 second.4.When " TRANSMIT2 " is displayed, press and hold thekey on the Mask key remote for more than 0.5 secondagain. The first and second counter codes are notcompared at this time.5.When " APPROVED " is displayed, the write operation iscomplete. Now the demonstration mode is initiated andthe test mode is terminated.(Note) In the same way as previous models, if 30 minuteshave elapsed with no code written, an error occursand the power is turned OFF.5. Method of initializing the Mask key (How to resetthe unit from the Mask key approved condition tothe factory condition)1.Enter the test mode. (See 1. How to enter the test mode)2." TRANSMIT1 " is displayed and the Mask key entryrequest mode is initiated. The display at this time shouldshow " ∗ ∗ " in place of " [ ] ".3.Press and hold the key on the Master key remote formore than 3 seconds.4.When " TRANSMIT2 " is displayed, press and hold thekey on the Master key remote for more than 3 secondsagain.5.When " APPROVED " is displayed, the Mask key iscleared, the demonstration mode is initiated, the testmode is terminated and the unit returns to the factorycondition.6. Method of clearing all Mask key-related data1.Enter the test mode. (See 1. How to enter the test mode)2.Press the CLK key to enter the Mask key registrationmode. " TRANSMIT1 " should be displayed now.3.Point the Master key remote toward the light sensor, andpress and hold its key for more than 3 seconds (until thelevel display shows the full condition).4.When " TRANSMIT2 " is displayed, hold the key on theMask key remote for more than 3 seconds again. If "TRANSMIT1 " is displayed in place of " TRANSMIT2 ",restart the procedure from step 3.5.When " APPROVED " is displayed, all security data iscleared and the unit returns to the condition before Maskkey writing with the EEPROM in the initial status.ATTENTIONAssembly of FPC(Flexible PC board) onto Roller ass’yTurn Roller ass’y by 2 times.Hook the end of Roller ass’y to the tongue.Insert the FPC into the slit of Roller ass’y then release theend of Roller ass’y and the tongue.
