CE NOTICE Marking by the symbol indicates compliance of the device to the EMC (Electromagnetic Compatibility) directive and to the Low Voltage directive of the European Community. Such marking is indicative that this device meets or exceeds the following technical standard: • EN 55022 "Limits and Methods of Measurement of Radio Interface Characteristics of Information Technology Equipment.
1 Replacing the Power Supply 1.1 Description: The Power supply used is a standard PC power supplies with special connectors mounted at Doremi Labs. It is best that you get the replacement from Doremi so it will have all the right connectors. 1.2 Removal Procedure: ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ 1.3 Disconnect all cables including power from the back of the V1. Remove the top cover of the V1. Unplug all power connectors from the V1 main board and drives.
2 Replacing the Power Switch ♦ ♦ ♦ ♦ ♦ Disconnect the power connector from the back of the V1 very important. Pull out the power switch from the front. Mark the direction of the switch (O to the right) and mark the colors of the wires. Remove all four connectors after marking the way they were connected. Install the four connectors on the new power switch: -Black and brown horizontally aligned. -Blue and white horizontally aligned.
MOUNTING SCSI DRIVES The V1 is factory set to SCSI ID6 by setting DIP switches 1, 2 & 3 on the back of the V1 to high, low & low. To avoid conflicts, Don't use this ID 6 for any drive to be installed. CAUTION NOTE: FOR VENTILATION PURPOSES, THE OPENEING OF THE TOP COVER SHOULD ALWAYS BE TOWARDS THE HARD DISK TRAYS AND NOT TOWARDS THE POWER SUPPLY. ALL INTERNAL CABLES SHOULD BE PLACED AT LEAST ONE INCH ABOVE THE CIRCUIT BOARD, USE CABLE TIES IF NECESSARY. 3.
3.3 Mounting one Kingston Data-Express removable drive system ♦ ♦ Disconnect all cables including power from the back of the V1 Prepare your Kingston receiver according to one of the following diagrams: ♦ Install the hard driveterminator in the resistors carrier (See Sections 0, 0, 0 for setup), connect the SCSI Id cable (SIP) use this jumper supplied (black/brown/red) setting to the correct jumpers onAthe Bhard drive (Check also the direction). Install the receiver on the bottom V1 tray.
3.4 Mounting two Kingston Data-Express removable drive systems ♦ 3.5 Repeat the procedure C. for both frames. Set the bottom tray to ID3 and the top one to ID 4. Mounting one Jaz and one Kingston Data-Express removable system ♦ ♦ Repeat procedure A. for the Jaz, set it to ID4 and install it on the top V1 tray. Repeat procedure C. for the Data-Express, set it to ID3 and install it on the bottom V1 tray. 3.
3.7 Setup of the Micropolis 3243av 4 GB hard drive. These are the two connectors that should be configured on the 3243av: POWER and SCSI CONNECTORS To Data-Express W2 B L K B R N R E D Red, Brown & Black wires on the bottom Rear View of the drive in the mounting position TP FROM BUS This is the only jumper that should be installed on W2 Bottom View of the drive W2 should only have one jumper to set the termination power from SCSI bus. That position is marked in the drawing above.
Setup of the Seagate Ultra SCSI hard drives 4 GB, 9 GB & 18 GB Seagate has 2 series of Ultra SCSI drives: Barracuda and Cheetah.

4 Replacing the V1 main board All PC boards are very sensitive to ESD. Make sure you touch the V1 power supply before any direct contact with the PC boards. The V1 main board is also refered to as DVP100. 4.1 Removing the V1 Main Board ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ 4.2 Remove all cables from the back of the V1. Remove the V1 top cover. Remove the (4) screws from the S-VIDEO connectors. Remove the (4) screws from the MIDI connectors. Remove the (4) screws from the XLR connectors.
4.3 Replacing the Flash EPROM on the V1 Main Board To replace the Flash EPROM on the RCV1 board: ♦ ♦ ♦ ♦ ♦ Remove all cables from the back of the V1. Remove the V1 top cover. Locate the socketed 32 pin PLCC IC (U6: NH29EE010) on the DVP100 PC board, note the direction of pin 1 (cut on one corner of the socket) and remove it using a special PLCC extractor tool. Install the new 32 pin PLCC IC in the socket.
5 Replacing the V1 Remote Control Board 5.1 Replacing the RCV1 board To replace the V1 remote control board called RCV1: ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ 5.2 Remove all cables from the back of the V1. Remove the V1 top cover. Remove the 2 knobs from the input level adjustement potentiometers. Remove the 2 nuts from the input level adjustement potentiometers. Unscrew and remove the scrub weel using a hex socket. Remove the 6 screws holding the RCV-PCB to the V1 front [panel].
6 Adjusting Sticky Caps on the V1 Remote Control If one or more caps are getting stuck when pressed, the following procedure should be followed for each of the sticky caps: ♦ ♦ ♦ ♦ ♦ Pull the cap to its normal position and try to identify which of the sides is too close to the edge of the lexan. Pull the cap out using a big enough plier with a good grip. File the cap from the side(s) that are too close to the edge by moving the cap back and forth on a file.
INSTRUCTIONS FOR INITIAL SETUP & TRANSPORT IMPORTANT !! ♦ Before powering-up the V1 unit, please connect the SCSI termination supplied on the rear external SCSI connector (If not there, the V1 will not operate properly). ♦ After powering-up, if your V1 has been ordered with a drive from Doremi Labs, you will be able to play the initial "video test" recording (In NTSC for USA, PAL for Europe) without the need of an external sync reference (Internal Sync. selected).
