CONTROLS, INDICATORS 1) Push down 2 pcs. of lock pins located at the lower left side on both A and B sides of 8 cm DVD-RAM disk by using the tip of a ball point pen, etc. Then, spin and move the lock pins out and around. 2

24、) Take out the 8 cm DVD-RAM disk out of the cartridge and place it in the indent of the DVD-RAM drive tray. 3) Extract the WinZip compressed software file “PD6VXXX.zip” and copy the newly created software update file “pd6mXXX.mot” to the top directory tree of the DVD-RAM disk. (“XXX” indicates the s

25、oftware version number. If the software version is V1.02, the software update file name will be “pd6m102.mot”.) 4) After copying the software, take out the 8cm DVD-RAM disk, put it back to the cartridge and load it to the PD-6 DVD-RAM drive. When putting a bare DVD-RAM disk back to the cartridge, be

26、 sure that the side A of the disk conforms with the cartridges A marking. 5) Power on PD-6. In the initialize stage, PD-6 automatically finds the software update file placed in the top directory tree and is put into the software update mode. The LCD example on the right indicates that the PD-6 MAIN

27、software is going to be updated to V1.02 using the software file “pd6m102.mot”. 6) In the condition that the LCD example on the right is displayed, press the ENTER key (knob) to update the software. PD-6 starts updating the MAIN software. The LCD shows “Erase ROM” (flashing) and then “Write PGM” (fl

28、ashing). 7) After updating the software is completed, PD-6 is automatically put initialized, booted up again and is put into the software update mode. Press the EXIT key. (Depending on the current software version, there is a case that powering off and then back on PD-6 might be required. Also there

29、 is a case that the display contents differ from those listed in this page.) 8) Confirm the software version by the “Version” SETUP menu ex- plained later.

30、 your PC environment; NOTE: As mentioned in the PD-6 owners manual, depending on the operating system running on your computer, an IEEE1394 driver software must be installed in your computer to allow to recognize the UDF formatted PD-6 DVD-RAM disk as a rewritable medium prior to the software update

31、. 1) Select the IEEE1394 Utility menu and press the ENTER knob. Then, turn the ENTER knob to right to select “CONNECT” and press the ENTER knob again. By putting PD-6 into the IEEE1394 mode, all functions are disabled. 2) Connect the IEEE1394 cable between PC (Desktop PC: 6-pin, Laptop PC: 4 or 6-pi

32、n) and PD-6 (4-pin) IEEE1394 ports. 3) Wait for a while until PC recognizes PD-6 with 8 cm DVD-RAM disk loaded as an external rewritable removable drive / disk. 4) Extract the WinZip compressed software file “PD6VXXX.zip” and copy the newly created software update file “pd6mXXX.mot” to the top direc

PD-6 starts updating the MAIN software. The LCD shows “Erase ROM” (flashing) and then “Write P

35、GM” (flashing). 8) After the software update is completed, power off PD-6 and then back on. (Depending on the software version, there is a case that PD-6 is automatically initialized and is booted up.) 9) Confirm the software version by the “Version” SETUP menu.

36、ce Manual 3-2. DVD-RAM Drive Firmware Update Procedures There are two firmwares for DVD-RAM drive, which can be updated by a similar method explained before. Although the DVD-RAM drive firmware update will not occur as many times as the MAIN PCB software update, read through the following explanatio

37、n for correct update procedures. 1) Copy the DVD-RAM drive firmware update file “mkXXXrev.bin” to the top directory of the DVD-RAM disk either by direct software file copy onto a 8 cm DVD- RAM bare disk or by putting PD-6 into the IEEE1394 mode and connecting to PC. 2) In the initialize stage, PD-6

38、automatically finds the firmware update file in the top directory tree and is put into the update mode. The example on the right indicates that there is a firmware update file “mk0b1rev.bin” exists in the top directory tree. 3) Press the ENTER knob to update the DVD-RAM drive firmware. The firmware

39、update remaining time starts counting down. It will take about 100 seconds (1 minute and 40 seconds) to complete the firmware update. 4) After the software update is completed, the message “Pls Power Off!” will appear on the PD-6 LCD. Power off PD-6 and then back on. (Depending on the software ver-

40、sion, there is a case that PD-6 is automatically initialized and is booted up again.) 5) Select “Reset setup memory” in the SERVICE menu ex- plained later in this manual, press the ENTER knob and press the ENTER knob again while “SURE?” is flashing on the LCD to reset the memory. 6) Confirm the soft
