SYSTEM Q is in FLAT Bla

27、nk skip is OFF. (C/R model) LEDs are white, no scanning. (VLCD model) 4. Special displays in Tuner When the following displays appear in tuner mode it shows a problem with the front end. “TNE2P NG” . F/E is not aligned and EEPROM is in reset (no settings) such as when shipped. “TNCON NG” . Cannot co

28、mmunicate with F/E (front end). 5. K3I switching Each time the Preset 6 key is pressed in Tuner mode, switches one at a time through the following sequence: AUTO Forced Wide Forced Middle Forced Narrow AUTO. When reset, displays the following in AUTO. AUTO . FMA Forced Wide . FMW Forced Middle . FMM

29、 Forced Narrow . FMN 6. CD receiver test mode specifications No automatic ejection during reset-start. Does not make a CD check in reset with a CD loaded. Using the Track up key jumps to the following tracks. No.9No.15No.10No.11No.12No.13No.14and back to No. 9 Using the Track down key moves 1 track

30、downwards from the track being played. 7. Audio items Momentarily pressing the Q key calls up audio adjustment mode. Pressing the key on the remote control calls up audio alignment mode. Continuous forward is disabled on the remote control. Bass/Middle/Treble are settable in 3 steps of MIN/ CENTER/M

31、AX with the Track up/down keys. Balance is settable in 3 steps of Left MAX/CENTER/Right MAX with the Track up/down keys. Fader is settable in 3 steps of Rear MAX/CENTER/Front MAX with the Track up/down keys. HPF is settable in 2 steps of THRU/220Hz with the Track up/down keys. LPF is settable in 2 s

32、teps of THRU/120Hz with the Track up/down keys. Bass f/Bass Q/Bass EXT/Middle f/Middle Q/Treble f do not appear in the audio alignment. 8. Menu items Momentarily pressing the CLK key calls up the Menu mode. The DNPP/SBF keys on the remote control calls up Menu mode. Continuous forward is disabled on

33、 the remote control. Calendar adjust, calendar display switching and calendar memo are eliminated from forward (FL model) In color alignment mode, Preset 1 is red, 2 is blue, 3 is green and 4 is white. (VLCD model). Contrast is set in 3 steps of 0, 5, 10 and the reset value is 5. (VLCD/LCD models) B

34、rightness adjustment is set in 3 steps of 0, 5, 10 and the reset value is 10. (Normal FL model) 9. Backup current measurement The MUTE terminal turns off 2 seconds (not 15 seconds) after being reset in ACC off (backup on). (The panel, CD and tape mechanisms are disabled during this time.) 10.

39、) No displays such as “CODE OFF” during Power-ON. Pressing the TI (AUTO) key during changer operation turns on 2zone. Cancel by pressing the TI (AUTO) key again. The P/S dot is lit during 2zone. Pressing the CLK key for 1 second or more during All OFF, calls up the Mask Key (security) write mode. Se

40、curity items Forced power-ON mode (all models) Even when writing is permitted by the security function (mask key), Power-on can be set for a 30 minute period each time the reset key is pressed while holding down the ATT key and Preset 4 keys. After 30 minutes elapses, can only be restored by using r

41、eset. How to register the security code for EEPROM (F/E) replacement (coded security models) 1. While holding the FM key and the preset 6 key, reset the unit. 2. Call up security register mode by pressing the CLK key. 3. Enter the code with the Preset 1/2/3/4 keys. For example, to enter the number,

42、“3510”. - Press the Preset 1 key 4 times. - Press the Preset 2 key 6 times. - Press the Preset 3 key 2 times. - Press the Preset 4 key 1 time. 4. Hold down the DISP key for at least 3 seconds and the message, “RE-ENTER” appears, so once again enter the code according to Step 3 above. 5. Hold down th

43、e DISP key for at least 3 seconds, and the message, “APPROVED” appears. 6. Cancel test mode. (See, 2. How to cancel the test mode.) Note: All clear cannot be performed on the security code for this model. Simple way to clear the security code (K type only) 1. During code request mode, press the VOL

44、UP key for at least 3 seconds while holding down the DISP key. (- will disappear) 2. Enter, “KCAR” with the remote controller as described below. (Same as on 00 model.) Press the remote controller 5 key twice, and press the Track Up key. (Enters a “K”) Press the remote controller 2 key three times,

45、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 app
