– 10 – CXP1021Q 1. Deck mode/portable mode selection A feature of the CXP1021Q is its ability to be used in both deck-type and in portable equipment. (a) Selection Selection is executed through Pin 39 (LOAD/DECK-PT). Mode selection is determined by the condition of this pin immediately after reset of the CXP1021Q. When Pin 39 (LOAD/DECK-PT) is high: Deck mode When Pin 39 (LOAD/DECK-PT) is low: Portable/radio cassette mode (b) Deck mode

• In deck mode the tray loading function is activated.
• Pins necessary for tray operation:
• The relation between Pin 40 (UNLOAD/Batt-W) and Pin 39 (LOAD/DECK-PT) is as follows. (c) Portable mode
• In portable mode, when the lid is closed the operation changes to TOC reading.
• Pin 39 (LOAD/DECK-PT) should be held "L".
• Pin 37 (Disc IN) should be connected to a switch that makes the pin go "L" when the lid is closed.
• Two pins used in deck mode can be employed to detect a reduced battery voltage.
• When Pin 40 (UNLOAD/Batt-W) is made "L" through the reduced voltage detection circuit, BATT is displayed.
• In addition, when Pin 40 (UNLOAD/Batt-W) is "L", forcing Pin 38 (Disc OUT/Batt-E) "L" induces the STOP state. For the loading motor Pin 40 (UNLOAD/Batt-W) goes "L" when tray is ejected Pin 39 (LOAD/DECK PT) goes "L" when tray is closed Pin 37 (Disc IN) goes "L" when the tray is closed Pin 38 (Disc OUT/Batt-E) goes "L" when tray is fully opened For the tray SW State Open (stopped) LOAD direction UNLOAD direction H H L H L H Pin 40/UNLOAD Pin 39/LOAD LOAD direction UNLOAD direction Tray

– 11 – CXP1021Q 2. Key combination selection This function can be used to reduce the number of keys needed. (a) Selection Selection is made through Pin 61 (KEYSEL). Selection is determined by the state of this pin immediately after reset of the CXP1021Q. When Pin 61 (KEYSEL) is high: keys are combined. When Pin 61 (KEYSEL) is low: keys are independent. (b) Operation when Pin 18 (KEYSEL) is high Key name Function differs depending on length of time pressed. If the length of time pressed is: 0.5 seconds or less keys function as tune select keys ( ) longer than 0.5 seconds keys function as fast-forward, rewind keys ( ) /, / /, /

• Pin 70 (EXTCTL), the external control output, is switched between "H" and "L" every time pressing EXCTL . Note)The voice cancel circuit is not incorporated. An external circuit is required when this function is used. Description of Operation 20. Test Mode Branching to Test mode is achieved by setting Pin 62 (TEST IN) to "L". When Pin 62 (TEST IN) is set "L" and Reset Start is executed, focus searching is repeated at the current pickup location. If a disc is loaded, the focus is turned on, the CLV-A and tracking sled servo are turned on, mute is turned off, and play is begun. fi In deck mode, the OPEN key can be used to operate the tray. When the tray closes, focus searching is begun. fi In portable/radio cassette mode, operation does not begin until the lid is closed. When the lid is closed, focus searching is begun. (a) Focus bias When reset is executed without a disc loaded, the lens is moved up and down in approximately one second intervals. (b) Running check When reset is executed with a disc loaded, focus searching, focus on, CLV-A, and tracking sled servo are set on, mute is turned off, and play is begun. At this time, the following key operations are possible. = All servo off = Repeated focus searching. When a disc is loaded, play is begun. = CLV-P, tracking on, sled on = CLV-A, tracking off, sled off = Fast-forward 200 track jump (during play only) = Fast-rewind 200 track jump (during play only) * During and operation only, the current track number is displayed in the Track No. field of the display. , ,
