CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. ATTENTION: POUR ÉVITER LES CHOCS ÉLECTRIQUES, INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE CORRESPONDANTE DE LA PRISE ET POUSSER JUSQU' AU FOND. The lightening flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. "WARNING" "TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. " SAFETY INSTRUCTIONS 1. Read instructions - All the safety and operating instructions should be read before the appliance is operated. Retain instructions - The safety and operating instructions should be retained for future reference. [. . . ] Connect the AC cable and turn on the power of D1624/D824. In this condition, the D1624/D824 is booted up using the system software inside the EPROMs. The next procedures to take are as follows. : Blinking OL 0 3 6 9 12 18 24 30 42 44. 1kHz _ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 20 D1624 / D824 5. Put the D1624/D824 into the Service Mode, rotate the jog dial, select "FlashROM" menu and press [EXECUTE/ YES] key. ("SURE?" is blinking in this condition. ) 6. Change the SW setting on the ROM CARD PCB assy from "EPROM" side to "FLASH" side while "SURE?" is blinking and then press the [EXECUTE/YES] key to copy the system software from EPROMs to Flash ROM. The display shows "Erase ROM", "Write ROM" and then "COMPLETED!" in order. In order to confirm that the D1624/D824 is correctly booted up using the system software inside the Flash ROM, turn off the power, disconnect the ROM CARD PCB assy and turn the power back on again. After the boot up confirmation, referring to the section "3. SOFTWARE UPDATE" (page 11), update the system software inside the Flash ROM through SCSI port again. 4-9. Free Block Check This mode is used to check the condition of the diskette inserted into an external SCSI drive connected to the D1624/ D824 or the internal E-IDE hard disk drive. The drive to be checked is the one currently selected drive by the SETUP menu "Drive_Sel?". : Blinking OL 0 3 6 9 12 18 24 30 42 44. 1kHz _ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Press the [EXECUTE/YES] key when "?" is blinking. The display indicates the free audio file numbers. OL 0 3 6 9 12 18 24 30 42 44. 1kHz _ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 If the Free Block indicates a large number even after formatting and no signal is recorded or recorded signal on the EIDE HDD is frequently skipped, the diskette / hard disk drive can be judged to be in a bad condition. 4-10. MIDI Date Set This mode is mainly designed for our manufacturer. When this menu is selected, pressing the [EXECUTE/YES] key would output the current time information in the shape of FEX (Fostex System Exclusive message) from MIDI OUT port. The internal RTC on the D1624/D824 which receives the information can be set to the current time. : Blinking OL 0 3 6 9 12 18 24 30 42 44. 1kHz _ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 21 D1624 / D824 5. ERROR CODE LIST The chart below indicates the error code number and corresponding description. Since the error code list is basically designed for our engineers to improve the software, the description is quite technical. If you find the D1624/D824 with one of the error codes displayed, we encourage you to update the software first. In case updating the software does not solve the problem, we would like you to inform us about details.
