22、ressing the FM key and the Preset 6 key at the same time. When the test mode is entered, all indicators light up. 2.Releasing the test mode Reset the unit by pressing the Preset 6 key. Note: The unit cannot be reset by simply turning ACC off, turning power off, or turning power off for a brief momen

23、t. 3.Voltage adjustment on the FM S-meter (1) Enter the test mode. (2) While pressing the Preset 1 key, keep on pressing the Preset 6 key. (3) When the adjustment is made, ADJ OK is displayed. When adjustment cannot be made, ADJ NG is displayed. 4.Writing SD voltage for the AM (1) Enter the test mod

24、e. (2) While pressing the Preset 1 key, keep on pressing the Preset 6 key, which results in writing SD. 5.Forced switching of K2I Auto/Manual In tuner-mode, keeping on pressing TI key, and the Auto and Manual modes can be swieched. The initial condition is manual modes, which is indicated by flashin

25、g DUAL dots. 6.Forced narrow/wide switchng of K2I In tuner-mode, when Preset 6 is pressed, forced narrow/ wide mode switching is made. The initial condition is in wide mode and the NEWS dot flashes. 7.CD receiver test mode specification By pressing the track-up key, the unit jumps to the following t

26、racks: No. 9 No. 15 No. 10 No. 11 No. 12 No. 13 No. 14 No. 9 (Goes back to the first position.) When the track-down key is pressed, the unit jumps to the previous track. 8.MD test mode specification After loading MD, the unit plays No. 7. Then, the unit jumps as follows each time it track-ups. No. 2

27、 No. 13 No. 23 No. 30 No. 34 No. 7 (Goes back to the first position.) When the track-down key is pressed, the unit jumps to the previous track. 9.Tape test mode In the initial step, the blank skip is turned off. 10.Audio-related items The volume is -10dB (on display, it is 30). The loudness is off a

28、nd CRSC is off regardless of functions. Buss/treble and balance/fader are to be adjusted by the up/down key to full-boost/fullcut and fullfront/fullrear respectively. The high-pass filter is adjusted by the up-key to throughput/100Hz/200Hz and, by the down-key, to 200Hz/100Hz/throughput. Other adjus

29、tments are the same as before. 11.Backup current measurement When reset in ACC-off condition (backup is on), the mute terminal goes off after 2 seconds instead of 15 seconds, when the ACC is tuned off in the test mode. (In this case, the panel/CD/C/MD mechanisms are not activated.) 12.Registering se

30、curity code after changing E2PROM at the services (Only for type M. However, RDS models are excluded) (1) Put the unit into the test mode (Refer to 1. Above for how to enter the test mode.) (2) Press SRC key to put the unit into the tuner mode. (3) Press Audio key for one second and put the unit int

31、o the menu mode. (4) Press FM/AM key and then select SECURITY. (5) Press track up/down key for full 2 seconds. (6) Press Preset 1, Preset 2, Preset 3, and Preset 4 and then input codes. Example: Inputting 3510. Preset 1 key 4 times. Preset 2 key 6 times. Preset 3 key 2 times. Preset 4 key once. (7)

32、Press DISP key for 3 seconds and confirm that APPROVED is displayed. (8) Release the test mode. (Refer to 2. Releasing the test mode above.) KDC-9015/8080R 6 13.Simplified method for clearing the security code (Only for type K) (1) When code is requested, continue pressing VOL UP key for three secon

33、ds while pressing the DISP key. (. disappear.) (2) Input KCAR, using the remote controller (the same as the 98 Model) Press Tenkey 5 twice and then press track-up key. (Inputting K) Press Tenkey 2 three times and then press track-up key. (Inputting C) Press Tenkey 2 once and then press track-up key.

34、 (Inputting A) Press Tenkey 7 twice and then press track-up key. (Inputting R) (3) Then, the security is released and the unit goes into the Tuner Mode. 14.Writing MASK KEY on line (E2PROM in initial codition) (1) While pressing the FM key and Preset 6 key, press reset key to enter the test mode. (2

35、) Press AUDIO key for full one second to put the unit into the menu mode. (3) Select the MASK KEY, using the FM key or AM key. (4)Press on the track up/down key to display TRANSMIT 1. (5) Point the MASK KEY to the light receptor and press it for 0.5 second or longer. (6) When TRANSMIT 2 is displayed

36、, press MASK KEY for 0.5 second or longer. When this is conducted, the counter codes for the first time and the second time will not be compared. (7) When APPROVED is displayed, writing is completed. Time the demonstration mode is set and the test mode is released. Note: After an elapse of 30-minuit

37、e period, during which no code is written, an error is effected and the device will power off. 15.Releasing MASK KEY requests (When reset or backup is off when MASK KEY is approved) (1) When power is turned on, TRANSMIT 1 is displayed and the unit goes into MASK KEY request mode. (2)Point the MASK K

38、EY to the light receptor and press it for more than 3 seconds (until the level display indicates full) (3) When TRANSMIT 2 is displayed, press the MASK KEY again for more than three seconds. At this point, when TRANSMIT 1 is displayed, repeat the process in (2) above for the second time. (4) When AP

39、PROVED is displayed, MASK KEY is approved and the unit turns power on. 16.Initializing MASK KEY (returning to the default condition from MASK KEY approved state) (1) While pressing the FM key and Preset 6 key at the same time, press RESET to enter the test mode. (2) TRANSMIT 1 is displayed and the u

40、nit goes into MASK KEY request mode. The display at this point will be * instead of . (3) Use MASK KEY release remote controller for more than three seconds. (4) When TRANSMIT 2 is displayed, press the MASK KEY for more than three seconds for the second time. (5)When APPROVED is displayed, the MASK

41、KEY is released and the demonstration mode is set. Then, the test mode is released, returning the unit into default condition. 17.Clearing from the MASK KEY (1) While pressing FM key and Preset 6 key at the same time, press RESET to enter the test mode. (2) Press the AUDIO key for full one second to

42、 put the unit into the menu mode. (3) Select MASK KEY, using track up/down key. (4) Press on the FM key or AM key for full two seconds and the unit will display TRANSMIT 1. (5) Point the MASK KEY release controller to the light receptor and press it for 3 seconds or longer. (Until the level display

43、indicates full.) (6) When TRANSMIT 2 is displayed, press MASK KEY for 3 seconds or longer for the second time. If TRANSMIT 1 is displayed, start again from (5) above. (7)When APROVED is displayed, E2PROM is cleared. The unit goes back to the condition described in Line 14: Writing MASK KEY on line (

44、E2PROM in initial condition) 18.Other Automatic panel closing does not occur in case a TAPE, CD, or MD is inserted. Panel is opened/closed when ATT key is turned On/Off. (A remote controller is used when turning ATT on.) The DNPP/SBF key of the remote controller (RC-510) is used for tuning the menu

45、mode On/Off. The OPEN/CLOSE key of the remote controller (RC-510) is used for tuning the audio mode On/Off. The feed on the menu will be feeds only for necessary features. CODE OFF and other displays will not be issued when the power is turned on. The dimmer of the FL model and contrast on the LCD m
