SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a > on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual.

PCB PARTS LIST 7 LIST OF HOLE PCB ASSEMBLIES 7 CONTRAST OF PCB ASSEMBLIES DWX2524, DWX2525 and DWX2516 are constructed the same except for the following : DWX2519 and DWX2526 are constructed the same except for the following : Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5 6 1 4 7 3 R 5 0 1 R 0 5 6 2 1 NOTES: 560 Ω 47k Ω 0.5 Ω 1 Ω RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 10 1 47 x

On the BPM display, "-8-" is displayed. Each time a HEADPHONES cue button (CH-1/CH-2/MASTER) is pressed, the level indicator LEDs corresponding to that channel are lit one by one, from the bottom. At first, all the LEDs are unlit. When a HEADPHONES cue button is pressed 7 times, the uppermost LED will be lit. Then when the same HEADPHONES cue button is pressed again, all the LEDs go dark. Thus, this process can be repeated from the beginning. 72 DJM-400 1 2 3 4 1 2 3 4 C D F A B E 7.1.2 Rewriting of the Software [How to rewrite the software for the DJM-400] • Rewritable programs for the DJM-400 1.

This pin does not have an internal pullup or pulldown. When this pin is used as a McBSP pin, this pin should either be driven externally at all times or be pulled up with a 10-kΩ resistor to a valid logic level. Because it is common for some ICs to 3-state their outputs at times, a 10-kΩ pullup resistor may be desirable even when an external device is driving the pin. 86 DJM-400 1 2 3 4 1 2 3 4 C D F A B E No. Pin Name I/O Pin Function GENERAL-PURPOSE INPUT/OUTPUT 0 (GP0) 1 GP0 [4](EXT_INT4) /AMUTEIN1 I/O General-purpose input/output pins GP0 [15:2, 0] As general-purpose input/output 0 (GP0 [x]) functions, these pins are software-configurable through registers. The "GPxEN" bits in the GPIO Enable register and the GPxDIR bits in the GPIO Direction register must be properly configured: GP0xEN = 1;GP0 [x] pin is enabled. GP0xDIR = 0;GP0 [x] pin is an input. GP0xDIR = 1;GP0 [x] pin is an output. Internal ROM Boot Pins GP0 [11:9] are used for selection of internal ROM boot options (SPI hardware or software booting from serial EEPROM or Flash, or SPI slave booting from host processor).

For proper device operation, GP0 [8] must be either left unconnected or externally pulled up with a 4.4-kΩ or lower resistor until reset is released. GP0 [7:4] function as general-purpose input/output 0 pins and also as external interrupts (default). • Edge-driven • Polarity independently selected via the External Interrupt Polarity Register bits (EXTPOL. [3:0]) GP0 [4] and GP0 [5] pins also function as AMUTEIN1 McASP1 mute input and AMUTEIN0 McASP0 mute input, respectively. The CLKOUT2/GP0 [2] pin functions as clock output at half of the device speed (default) or this pin can be programmed as GP0 [2] pin. The GP0 [0] pin can function as a general-purpose I/O and is external interrupt capable through interrupt sharing. For proper device operation, GP0 [14] must be externally pulled down with a 2-kΩ resistor until reset is released. 2 GP0 [6](EXT_INT6) 4 GP0 [5](EXT_INT5) /AMUTEIN0 5 GP0 [7](EXT_INT7) 56 CLKOUT2/GP0 [2] 108 GP0 [0] 111 GP0 [8] 113 GP0 [3] 116 GP0 [9] 117 GP0 [10] 118 GP0 [11] 119 GP0 [12] 121 GP0 [13] 122 GP0 [14] 123 GP0 [15] GENERAL-PURPOSE INPUT/OUTPUT 1 (GP1) 75 ED6/GP1 [6] I/O The ED7 - ED0 pins are muxed with general-purpose input/output 1 (GP1) pins. The EMIFDIS bit in the DEVCFG register controls the function of these muxed pins, EMIF is default. As general-purpose input/output 1 (GP1 [x]) functions (EMIFDIS = 1), these pins are softwareconfigurable through registers. The "GPxEN" bits in the GPIO Enable register and the GPxDIR bits in the GPIO Direction register must be properly configured: GP1xEN = 1;GP1 [x] pin is enabled. GP1xDIR = 0;GP1 [x] pin is an input. GP1xDIR = 0;GP1 [x] pin is an output. 76 ED7/GP1 [7] 79 ED4/GP1 [4] 80 ED5/GP1 [5] 81 ED3/GP1 [3] 82 ED2/GP1 [2] 83 ED1/GP1 [1] 84 ED0/GP1 [0] RESERVED FOR TEST 85 RSV I Reserved.
