Welcome to Project 64!

The goal of Project 64 is to preserve Commodore 64 related documents
in electronic text format that might otherwise cease to exist with the
rapid advancement of computer technology and declining interest in 8-
bit computers on the part of the general population.

Extensive efforts were made to preserve the contents of the original
document.  However, certain portions, such as diagrams, program
listings, and indexes may have been either altered or sacrificed due
to the limitations of plain vanilla text.  Diagrams may have been
eliminated where ASCII-art was not feasible.  Program listings may be
missing display codes where substitutions were not possible.  Tables
of contents and indexes may have been changed from page number
references to section number references. Please accept our apologies
for these limitations, alterations, and possible omissions.

Document names are limited to the 8.3 file convention of DOS. The
first characters of the file name are an abbreviation of the original
document name. The version number of the etext follows next. After
that a letter may appear to indicate the particular source of the
document. Finally, the document is given a .TXT extension.

The author(s) of the original document and members of Project 64 make
no representations about the accuracy or suitability of this material
for any purpose.  This etext is provided "as-is".  Please refer to the
warantee of the original document, if any, that may included in this
etext.  No other warantees, express or implied, are made to you as to
the etext or any medium it may be on.  Neither the author(s) nor the
members of Project 64 will assume liability for damages either from
the direct or indirect use of this etext or from the distribution of

User's manual


[ Graphic omitted: black & white front view of monitor ]


  Introducing your monitor
Please read this brief guide carefully before you try to use your
monitor.  This manual shows you have to connect the monitor and use it
in various operating modes. It also explains the picture controls and
gives instructions for the installations, use and service of the 1802.

The Commodore 1802 is a full-color monitor with monochrome function
monitor meaning it can display computer output in 40-column screen
width. Some computers, like the Commodore 64, display screen output in
a 40-column format. You can select the operating mode you want with
the flick of a switch. The switch setting depends on the computer you
have hooked up to the 1802 monitor.

The 1802 can be used in three operating modes: The three 40-column
modes are composite, separated and monochrome on a green ground
Screen. The following chart shows recommended operating modes by
computer mode. Depending on your computer, you'll find that certain
operating modes give better displays while others may not even produce
a picture.

          Recommended Operating Mode by Computer Model
 =========================================================
         40-Column Composite     Separated   Monochrome
 =========================================================
 Commodore 64                       *
 Plus/4                             *
 Commodore 16                       *

The 1802 monitor features a 13" screen (measured diagonally) and
operates on the Phase Alternation by Line (PAL). Be sure to take note
of the warnings in this manual, and do not remove the back cover or
otherwise attempt to service this monitor for safety reasons. If you
have problems with your monitor that are not covered in this manual,
see your Commodore dealer or a qualified technician.

Connecting the monitor to a computer
The monitor connecting cable connects your monitor to a Commodore
personal computer. Before you connect the cable, turn off the power to
both your personal computer and the monitor.

There are two different cables included with the 1802 that you can use
to connect the monitor to your computer.

1. One kind of cables has three different-colored jacks on one end and
a larger rounded end.

The kind of cable you'll use depends on your computer. The three
plugged video cable is used for 40-column display (for composite and
separated modes and monochrome on green ground screen). To find out
which kind of cable you should use, see the above table and look at
the audio/video connector(s) on your computer. See your computer's
user manual if you don't know where this connector is.

[ Graphic omitted: black & white rear view of monitor and commodore
C64c with a three jack video cable connected  ]

To connect a three-jack cable to the rear of the monitor, follow these
instructions, which clarify the diagrams:

1. Plug the rounded end with eight PINS inside (the larger end of the
  cable) into the VIDEO connector port on your computer. Make sure the
  small dent on the metal end of the cable that you plug into the
  computer is facing up, and push the cable end firmly in.

2. Plug the three jack ends of the cable into the three sockets on the
   back of the monitor. The jacks and the sockets are colour coded:

   * the white output jack plugs into the AUDIO I or II socket (white)
     on the monitor.
   * the yellow output jack plugs into the luma or monochrome socket
     (yellow).
   * the red output jack plugs into the chroma socket (red).

3. Set the video mode switch to sep (for separated luma and chroma)
  for a sharp color 40-column picture display.

Safety precautions

 This unit has been engineered and manufactured to assure your
personal safety. But improper use can result in potential electrical
shock or fire hazards. In order not to defeat the safeguards
incorporated in this monitor, observe the following basic rules for
its installation, use and servicing. Follow all warnings and
instructions marked on your video monitor.

Installation

1. Your set is equipped with a three-pronged 240-volt AC line plug.
  This safety feature allows the plug to fit into the power outlet
  only one way. If it is necessary to use a 3- prong to 2- prong plug
  adapter, make sure the adapter is properly grounded according to its
  instructions.

2. Operate the set only from a power source as indicated on the set or
  refer to the user's manual for this information. If you are not sure
  of the type of power supply to your home, consult your dealer.

3. Overloaded AC outlets and extension cords are dangerous. So are
  frayed power cords and broken plugs. They may result in a shock or
  fire hazard.  Call your service technician for replacement.

4. Do not allow anything to rest or roll over the power cord, and do
  not place the set where the power cord is subject to traffic or
  abuse. This may result in a shock or fire hazard.

5. Do not use this monitor near water - for example, near a bathtub,
  washbowl, kitchen sink, laundry tub, in a wet basement, or near a
  swimming pool, etc.

6. Sets are provided with ventilation openings in the cabinet to allow
  heat generated during operation to be released. If these openings
  are blocked, heat built up within the set can cause failures which
  may result in a fire hazard. Therefore:

   * Never block the bottom ventilation slots by placing it on a bed,
     sofa, rug, etc.
   * Never place a set in a "built-in" enclosure unless proper
     ventilation is provided ;
   * Never cover the openings with cloth or other material;
   * Never place the set near or over a radiator or heat register.

7. To avoid personal injury:
   * Do not place a set on a sloping shelf unless properly secured;
   * Use only a cart or stand recommended by the manufacturer;
   * Do not try to roll a cart with small casters across thresholds or
     deep-pile carpets;
   * Wall- and shelf-mounted installations should use factory approved
     instructions.
Use

8. Always turn the set off it is necessary to leave the room for more
  than a short period of time. Never leave a set on when leaving the
  house. A malfunction may result in a fire hazard.

9. Caution children about dropping or pushing objects into the set's
  cabinet openings. Some internal parts carry hazardous voltages and
  contact can result in a fire or electrical shock.

10. Unplug the set from the wall outlet before cleaning the face of
  the picture tube. Use a slightly damp (not wet) cloth. Do not use an
  aerosol directly on the picture tube since it may overspray and
  cause electrical shock.

11. Never add accessories to a set that has not been designed for this
  purpose. Such additions may create an electrical shock hazard.

12. For added protection of the set during an electrical storm or when
  the set is to be left unattended for an extended period of time,
  unplug it from the wall outlet. This will prevent shock and fire
  hazards due to lightning or power-line surges.

13. Do not bring magnetic devices such as magnets or motors near the
  picture tube. They may have a negative effect on the color purity of
  the picture.

14. Sometimes you may feel static electricity when you touch the
  surface of the picture tube. This is normal for any TV set or
  monitor and is harmless to the human body.

Service

15. Unplug the set from the wall outlet and refer servicing to
  qualified service personnel under the following conditions:

   A. When the power cord or plug is damaged or frayed.
   B. If liquid has been spilled into the set.
   C. If the set has been exposed to rain or water.
   D. If the set does not operate normally by following the operating
     instructions. Adjust only those controls that are covered in the
     operating instructions, as improper adjustment of other controls
     may result in damage and will often require extensive work by a
     qualified technician to restore the set to normal operation.
   E. If the set has been dropped or the cabinet has been damaged.
   F. When the set exhibits a distinct change in performance-this
     indicates a need for servicing.
   G. If snapping or popping from the monitor is continuous or
    frequent during operation. It is normal for some sets to make
    occasional snapping or popping sounds, particularly when being
    turned on or off.

16. Do not attempt to service this monitor yourself, as opening or
  removing covers may expose you to dangerous voltage or other
  hazards. Dangerous high voltage is present even when the monitor is
  unplugged. Refer all servicing to qualified service personnel.

17. When replacement parts are required, have the service technician
  verify in writing that the replacements he used have the same safety
  characteristics as the original parts. Use of manufacturer's
  specified can prevent fire, shock or other hazards.

18. Upon completion of any service or repairs to the set, please ask
  the service technician to perform the safety check described in
  the manufacturer's service literature.
