36、D mechanism clock line 99P94MS_DAI/OCD mechanism data line 100P95ONC MICROCOMPUTERS DESCRIPTION TEST MODE 1.Entering the test mode Reset the unit by pressing 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

37、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 moment. 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 th

38、e 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 mode. (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

39、-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 flashing 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 con

40、dition 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 tracks: 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

41、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 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

42、 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 and 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/fullre

43、ar 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 adjustments 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 second

44、s 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 security 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.

45、 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 into 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,

46、 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) 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.) 13.Simpli

47、fied method for clearing the security code (Only for type K) (1) When code is requested, continue pressing VOL UP key for three seconds 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.

48、 (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. (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 MAS

49、K 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) 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, 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
