How to enter the test mode • Reset the unit while holding preset 1 key and preset 3 key. 2. How to exit from the test mode • RESET • POWER OFF • ACC OFF • Bu OFF • Panel detach 3. Initial status in test mode • Sources : ALL OFF • Display : All segments are lit. • Volume : -10 dB (displayed as 30) • LOUD : OFF • CRSC : OFF regardless of the presence of switching function. • SYSTEM Q : Flat • BEEP : ON • DEMO : OFF 4. Special display during Tuner mode If the following display appears during the TUNER mode, the front end is defective. • "TNE2P NG": EEPROM remains in the initial value (don't care) because the product is shipped without passing the F/E adjustment process. • "TNCON NG": Communication with the F/E is not possible. 5. Forced switching of K3I Every pressing of the Preset 6 key during the TUNER mode, changes the status from Forced middle → Forced narrow → AUTO → Forced wide → Forced middle. When the product is set to the Forced middle: FMM in the initial state, the following message appears. • Forced middle : FMM • Forced narrow : FMN • AUTO : FMA • Forced wide : FMM 6. Test mode specifications of the CD receiver • Forced eject operation is prohibited during the reset start mode. CD cannot be recognized when the product is reset with CD remains inserted. • Track jump takes place to the following track when the Track up key is pressed. No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13 → No. 14 → No. 9 (The cycle restarts from here.) • When the Track down key is pressed, track returns back by one track during playback. 7. Audio system • The product enters the audio adjustment mode when the Q key is pressed momentarily. • Continuous advance operation from remote control is prohibited. • The Bass/Middle/Treble is adjusted to either one of the 3 steps of MIN/Center/MAX with Track up/down key. • Balance is adjusted to either one of the 3 steps of Left MAX/Center/Right MAX with Track up/down key. • Fader is adjusted to either one of the 3 steps of Rear MAX/Center/Front MAX with Track up/down key. • HPF (high-pass filer) is adjusted to either Through or 220 Hz with Track up/down key. • LPF (low-pass filer) is adjusted to either Through or 120 Hz with Track up/down key. • Bass f/Bass Q/Bass EXT/Middle f/Middle Q/Trable f do not appear on the audio adjustment. 8. MENU system • The product enters the MENU mode when the CLK key is pressed momentarily. • The product enters the MENU mode when the DNPP/ SBF key of the remote control is pressed. • Continuous advance operation from remote control is prohibited. • The calendar adjustment, calendar display switching and calendar memo are deleted from the advance operation. (FL model) • Red is set by the preset 1, blue by 2, green by 3 and white by 4 in the color adjustment mode. (VCLD model) • Contrast can be adjusted in 3 steps of 0/5/10. Initial value is 5. (VCLD/VCLD model) • Brightness can be adjusted in 3 steps of 0/5/10. Initial value is 10. (Normal FL model) 9. Backup current measurement If RESET is activated in the ACC OFF state (when BACKUP button is turned ON), the MUTE terminal turns OFF in 2 seconds, not in 15 seconds. (At this time, the panel/CD/ TAPE mechanism does not operate.) www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 KRC-665R/591/591V/591Y/591YV 7 TEST MODE 2.Enter the security registration mode by pressing the CLK key. 3.Enter the CODE by pressing the Track up/down and AM/ FM key. Example: To enter "3510" • Press the FM key four times. • Press the Track up key once and the FM key six times. • Press the Track up key once and the FM key twice times. • Press the Track up key once and the FM key once times. • When the AM key is pressed, the codes are searched in reversed direction. When Track down key is pressed, the entry digits return. 4.When the DISP key is pressed for three seconds, the message "RE-ENTER" appears. Then enter the code referring to step 3. 5.Press the DISP key for three second so that the message "APPROVED" appears. 6.Quit the test mode. (See item 2. How to quit the test mode.) (Note) The security code of this model cannot be all cleared. • Simple security code clear procedure (K type only) 1.Press the VOL UP key longer for 3 seconds while pressing the DISP key during requesting the code. (The message ---- disappears.) 2.Enter "KCAR" from remote control. (Same as the 00 model) • Press the 5 key twice on remote control and press the Track up key. (Enter "K".) • Press the 2 key on the remote 3 times, then press the Track Up key. (This enters "C".) • Press the 2 key on the remote once, then press the Track Up key. (This enters "A".) • Press the 7 key on the remote twice, then press the Track Up key. (This enters "R".) 3.The security is released and the product enters the ALL OFF mode. 4.If incorrect code is entered by mistake, the product enters the code-requesting mode. 10. Special display when the display is All ON If the PRESET key is pressed while all displays are turned on by ALL OFF, the following display appears. PRESET 1 Version display (8 digits, Month/Day/Hour/Minute) (Display) xxxxxxxx System microcomputer PRESET 2 All displays are turned on. Short press : Power-ON time display PRESET 3 Long press : Power-ON time is cleared.
