1084S High Resolution Monitor 1. Introducing your Monitor The Commodore 1084S is a full-color, 13 inch monitor for use with the Commodore 64, Commodore 128, Commodore PC and the Amiga family of computers. The monitor provides audio output in stereo for use with computer systems with stereo capabilities (like the Amiga computers). Your 1084S operates on the Phase Alteration Line Standard (PAL). This manual explains how to connect the 1084S monitor to your computer and how to use the various operating modes and picture controls. The 1084S works in four different operating modes: Composite (PAL standard), Separated LCA (Luma-Chroma-Audio), Digital RGBI (Red/Green/Blue Intensity), and Analog RGB. It also allows both a40-column screen display, for use in Composite and Separated modes, and an 80-column display for Digital and Analog RGB modes. The mode you choose will depend on the type of computer you are using. Before you proceed any further, check to make sure you have received everything: * One 1084S monitor * Cables: * For connecting an Amiga Computer--one cable with a 23-pin D (rectangular) connector on the computer end and a 9-pin D (rectangular) connector on the monitor end (provides an Analog RGB display). * For connecting an Amiga's audio capabilities -- one cable with two RCA plugs on each end. * Power cable for connecting the 1084S to an AC power source. * Warranty card NOTE: The following monitor cables are also available for use with the 1084S. These cables can be purchased from your Commodore dealer separately. . For connecting a Commodore PC or Commodore 128 -- one cable with a 9-pin D connector on the computer end and a 9-pin D connector on the monitor end (provides RGBI display). . For connecting a Commodore 128 or Commodore 64 -- one cable with an 8-pin DIN connector on the computer end and 3 phono plugs on the monitor end (provides Separated LCA display). Except for the power supply cable, the cables included with your 1084S monitor are RF shielded cables. Be sure to use only RF shielded cables when connecting this monitor to a computer. The chart below indicates the operating modes suitable to the type of computer you are using: Recommended Operating Mode by Computer Model 40-Column display 80-column display Separated Digital Analog Composite LCA RGBI RGB Amiga X Commodore PC X Commodore 128 X X Commodore 64 X X 2. Control Locations and Functions Before you connect your monitor to your computer, you should familiarize yourself with the location and function of the various control knobs, switches, and ports on both the front and rear of the 1084S. Because the 1084S is a universal monitor and can accommodate several types of computers, there are several ports and connectors on the monitor's cabinet. However, if you are only using your monitor with one type of computer, you will only need to use a few of the ports. (See diagram on next page.)

Connecting the Composite Display Some older C64's have a 5-pin DIN video connector which outputs composite video. To attach your 1084S to this older style C64, a 5-pin DIN video cable is required (not included, but commonly available at many stores that carry the C64 line). Set the CVBSIRGB switch on the rear of the monitor to CVBS mode. Insert the 5-pin DIN connector into the Video port on your Commodore 64, and insert the phono jack into the port labeled CVBS/L on your 1084S. Set the CVBS/LCA switch on the rear of the monitor to the CVBS position. 3.5. Connecting the Monitor to the Mains (for U.K. only) Your 1084S monitor is designed to operate from an a.c. mains supply of 220-240 volts, 50 Hz. If the mains voltage in your home is different from this, consult your dealer. Stabilising circuits ensure satisfactory performance within normal supply variations. IMPORTANT. This apparatus must be earthed. This can be achieved by fitting a 3-pin plug. The wires in the earthed mains lead are coloured according to the following code: BLUE = Neutral BROWN = Live GREEN/YELLOW = Earth If the mains plug (or adaptor) contains a fuse, the value of this fuse should be 3 Amp. Alternatively, if another type of plug (not fused) is used, the fuse at the distribution board should not be greater than 5 Amp. If the colors of the wires in the mains lead do not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The BLUE wire should be connected to the terminal marked "N" or coloured black. The BROWN wire should be connected to the terminal marked "L" or coloured red. The GREEN/YELLOW wire should be connected to the terminal marked "E" or earth symbol, or coloured green and yellow. Before replacing the plug cover, make certain that the cord grip is clamped over the sheath of the lead -- not simply over the three wires. 4.
