# SAFETY INSTRUCTIONS # INFORMATIONS
1. Parts identified by the } symbol are critical for safety. SYMBOLS FOR PRIMARY DESTINATION
Replace them only with the parts number specified. Unit destinations are indicated with letters as shown below.
2. In addition to safety, other parts and assemblies are
specified for conformance with such regulations as those Symbols Principal Destinations
applying to spurious radiation. A U.S.A
These must also be replaced only with the specified B England
replacements. E Europe
Examples : Noise blocking capacitors, noise blocking filters, J Japan
etc. V Germany
3. Use specified internal wiring. Note especially : X1 Japan
1) Wires covered with PVC tubing
X4 Universal Area
2) Double insulated wires
3) High voltage leads
4. Use specified insulating materials for hazardous live parts.
Note especially : MAKE YOUR CONTRIBUTION TO PROTECT THE
1) Insulation Tape ENVIRONMENT
2) PVC tubing Used batteries with the ISO symbol for recycling as
3) Spacers (insulating barriers) well as small accumulators (rechargeable batteries),
4) Insulation sheets for transistors mini-batteries (cells) and starter batteries should not
5) Plastic screws for fixing micro switches be thrown into the garbage can.
Please leave them at an appropriate depot.
5. When replacing AC primary side components (trans-
formers, power cords, noise blocking capacitors, etc.), wrap
the ends of the wires securely around the terminals before PRECAUTIONS FOR LITHIUM BATTERY
soldering. The lithium battery may explode when incorrectly replaced.
[OBSERVE THE FOLLOEING WHEN REPLACING]
· Replace with the same make and type or equivalent recom
mended by manufacturer.
· Place battery in correct polarity.
· Do not short the terminals.
· Do not charge battery.
6. Make sure that wires do not contact heat producing parts · Do not dispose of battery in fire.
(heat sinks, oxide metal film resistors, fusible resistors,
etc.).
7. Check that replaced wires do not contact sharp edged or
pointed parts.
8. Also check areas surrounding repaired locations.
9. Make sure that foreign objects (screws, solder droplets,
etc.) do not remain inside the set.
SAFETY CHECK AFTER SERVICING
After servicing, make measurements of leakage-current or
resistance in order to determine that exposed parts are
acceptably insulated from the supply circuit. The leakage-
current measurement should be done between accessible
metal parts (such as chassis, ground terminal, microphone
jacks, signal input/output connectors, etc.) and the earth ground
through a resistor of 1500 ohms paralleled with a 0.15 µF
capacitor, under the unit's normal working conditions.
The leakage-current should be less than 0.5 mA rms AC. The
resistance measurement should be done between accessible
exposed metal parts and power cord plug prongs with the
power switch (if included) "ON". The resistance should be
more than 2.2 M ohms.

IV. SUPPLEMENTARY INFORMATION
1. Test Mode
While pressing the SHIFT button, press the CANCEL button to enter the DEBUG PAGE. To leave the DEBUG
page, press the MAIN SCREEN button. Return to the DEBUG PAGE from any TEST MODE by pressing the
CANCEL button while the SHIFT button is being pressed.
1-1. F1 (BUFFERS)
For confirmation of DISK BUFFERS LEVEL.
1-2. F3 (PANEL)
For confirmation of FADER TOUCH SENSE operation.
F1/F2 (RED TRACK LEDS)
To check whether red LED operation is correct or not.
The RECORD/EDIT SELECT LED, SIGNAL CLIP LED will light up in red.
All other LEDs will light.
F3/F4 (GREEN TRACK LEDS)
To check whether green LED operation is correct or not.
The RECORD/EDIT SELECT LED, SIGNAL CLIP LED will light up in green.
NOTE: After LED CHECK, even when the DEBUG mode has been escaped from, all LED indicators will go
out and only renewed modes will light up in order.
1-3. F4 (AUDIO)
The input AUDIO signal will be output to dircet according to display indicator specification. The main
purpose of this function is for factory testing.
1-4. F2 (MIX DSP) F6 (PATCH)
Not operational at V1.0.
2. PANEL OPERATION TEST MODE
This mode is operated by the OPERATION CPU and is not affected by the CPU circuit of the CPU PCB. This test
mode will operate even if the CPU PCB is not operating properly. Turn the power on while pressing down the
REWIND, FAST FORWARD, STOP and PLAY buttons.
This mode can be used to confirm correct operation of the SWITCH, FADER VR, MONITOR VR, JOG, SHUTTLE
and ENCODER. However, A/B SW, LINE/MIC SW, TRIM, TB LEVEL, PHONE LEVEL are omitted.
NOTE: FADER operation directly after power has been input cannot be tested.
3. OTHER HIDDEN MODES
3-1 With the SHUTTLE knob turned fully to the right, turning the power on will immediately access the VERSION
UP mode via the USB.
3-2 With the SHUTTLE knob turned fully to the left, turning the power on will boot up the system without
running a hard disc check.
This mode is convenient when the system will not startup because of hard disc data.
3-3 With the SHUTTLE knob turned 1/4 to the left, turning the power on will check hard disc content and start up
the system in PROJECT initial settings. Normally the DPS24 starts up in the last PROJECT created. This
mode is convenient when there is a problem with the last PROJECT data and the system won't start up.

work in any other slot besides SLOT 1.
When the DPS24 power is turned on, the SELF CHECK function will operate to check each CHIP. If a fault is found
somewhere, FAILED will appear and operation will stop.
FAILED will appear when nothing after MIDI SPDIF, WCLK, ASCII are connected, but this is not an indication of
faulty operation.

5. Confirm the displayed OS version. If not displayed, repeat the procedure.
6. If the correct version is displayed, press the F6(YES) button.
7. Press the F6 (OK) button.
8. Reboot the DPS24.
· OS UPDATE FROM USB
The OS update can be made from the PC via the USB port.
You must have the "OS Loader software for DPS24".
The following files are required for the update:
dps24usb.sys (USB set up file)
dps24usb.inf (USB set up file)
usbrom.exe (USB transmission software)
dps24.bin (OS file for DPS24)
These files must be placed in the same folder. (eg. c:\DPS24)
Installing the USB drivers:
1. Connect USB cable between DPS24 and PC.
2. Power up the PC and let it complete the boot up process.
3. Power up the DPS24.
