DISPLAY CD PLAY MODE Select track Play display, the indicator light PLAY turn on. Program display Pause display, the track number flash, and the indicator light turn off. Program play, the indicator light turn on. The current track repeat play, the REPEAT indicator flash. All the track repeat play, the REPEAT indicator turn on. HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2008.03.24 Page 7 of 12 SC9636-006 In random mode, display track number for 5 seconds, and display circulate light for 5 seconds. Explanation of system operation according to application circuit: 1. If the Door SW input is “close” after resetting, the system starts the CD initialization and the display shows“- -”. If a disc is detected, the system will enter the stop mode and the display shows the total number of tracks. If the end of the tune of final track is reached, the system will go to stop mode and the display shows the total number of tracks. (it can set auto play according to the AUTOP1 and AUTOP2). 2. Function Keys: 1) PLAY key: When the system is STOP mode, if the key PLAY is pressed, the track number of the purpose will be reached and played. If the PLAY key is pressed during the CD play mode, the system goes to the pause mode from the play mode. If the PLAY key is pressed during the CD pause mode, the system returns to the play mode. 2) STOP key: If STOP key is pressed during the CD play mode, the system stops the disc motor, and moves the pickup the most inside. In the stop mode, display shows the total number oh tracks. 3) NEXT key: Use to select next track or fast forward play. While the key is holding continuously over 1 second during CD play mode, the current track is playing fast forward. Otherwise the system goes to next track. 4) PREV key: Use to reach back the tune head of the current track or select previous track of fast backward. If the key is pressed once, the system reaches back the tune head of current track. And the key is pressed twice in one second; the system goes to previous mode and goes to previous track. While the key is holding continuously over 1 second during CD play mode, the current track is playing fast backward. 5) 6) PROG key: use to go to program mode and save any desired track up to 20 in any order. REPEAT: If REPEAT key is pressed. The system changes the repeat mode cyclically from the no repeat mode the repeat-1 mode and then to repeat-all mode. 7) 3. Random: If Random key is pressed during the stop mode, the system searches at random and plays it. Display: 2 digits LED display. 1) If a disc isn’t detected, the CD function will become ineffective and display shows” NO”. 2) Display shows“- -”during the CD initializing. (Flashing) 3) If STOP key is pressed during the CD initializing, the display shows“- -”.（no flashing） 4) The display shows “7” not “07”during playing track 8. 5) The display shows the flashing track number in pause mode. 6) When system is STOP mode, the display shows total number of tracks. HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2008.03.24 Page 8 of 12 SC9636-006 7) In program mode, the flashing display number is the register number and the no-flashing display number is the track number chosen to register. 8) REPEAT display is on for in repeat mode. It flashes in REPEAT ONE mode. It does not flash in REPEAT ALL mode. 9) Program/Play display is on for playing mode. It flashes for Program status and program playing. 10) The LED flashes from A to F during random play mode. 11) The display shows“0 0”when the door SW is opened. 4. Program Modes: Any desired track up to 19 can be played in any order by program play. 12) If Program key is pressed during the CD Stop mode, the system goes to the program mode. 13) If Next or Previous key is pressed, the system chooses the track number which it wants to register. 14) If Play key is pressed during the system holding the program of more than one, it starts the program play. If Next or Previous key is pressed during the program play, the system skips to next or previous program. 15) If Stop key is pressed during the program play, the system stops the program play, and goes the stop mode. Until Stop key is pressed during the stop mode, the system keeps the contents of the program. If Stop key pressed during the program mode, the system removes the contents of the program, and cancels the program mode. 5. Random mode: 1) If Random key is pressed during the stop mode, the system searches at random and plays it. 2) The track will be play once only. 3) If whole track was finished during the random mode or if Stop key is pressed during the random mode, the system goes to the stop mode and cancels the random play mode. 4) When the PLAY key is paused, the STOP key, PROG/REPEAT key, REPEAT key is activate. 5) If the Next key is pressed during the random play mode, the system skips next at random. If Next key is pressed on the tune of the final track, the system searches next lap at random. 6) If previous key is pressed during the random play mode, the system searches the beginning of the current track, but doesn’t skip track down. 7) While Next or Previous key is pressed more than 1 second, it enters fast forward mode or fast backward mode. 8) 6. The LED display flashes from A to F in random play mode. Fast forward/ fast backward: 1) While the Next or Previous key is holding continuously over 1 second during the CD play mode, the current track is playing FF/FB. 2) By leaving the Next or Previous key, the system cancels the FF or FB replay. 3) If the system reaches the tune head of the head track of the CD, it cancels the FB replay. And if it reaches the tune head of current track of the CD during the repeat 1 mode and program play mode, it cancels FB replay. 4) During FF replay, the system is the repetition regeneration of 6 [track], during the FB reply, the system HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2008.03.24 Page 9 of 12 SC9636-006 is the repetition regeneration of 7[track]. And 1[track] is 62[ms] interval. 5) 7. During the FF or FB replay, the system has the attenuate level of –12[db]. STOP mode: 1) If the Stop key is pressed during the CD play mode, the system stops the disc motor, and moves the pickup the most inside. 2) In the stop mode, display shows the total number o flacks.
