WARNING
The SERVICE PERSONNEL should have the appropriate technical training, knowledge and
experience necessary to:
•Be familiar with specialized test equipment, and
•Be careful to follow all safety procedures associated with high voltage CRT circuit designs to
minimize danger to themselves and their coworkers.
To avoid electrical shocks, this equipment should be used with an appropriate power code and be
connected only to a properly grounded AC outlet.
This equipment utilized a micro-gap power switch. Turn off the set by first pushing the front panel
power switch. Next, remove the power cord from the AC outlet.
To prevent fire or shock hazards, do not expose this unit to rain or moisture.
This symbol warns the personnel that un-insulated voltage within the unit may have sufficient
magnitude to cause electric shock.
This symbol alerts the personnel that important literature concerning the operation and
maintenance of this unit has been included.
Therefore, it should be read carefully in order to avoid any problems.

PRODUCT SAFETY CAUTION
1. When parts replacement is required for servicing, always use the manufacturer's specified replacement.
2. Comply with all caution and safety-related notes on the product display chassis and picture tube.
3. When replacing the component, always be certain that all the components are put back in the place.
4. When servicing display monitor unit, it is required that the provided lead dress is used in the high voltage
circuit area.
5. It is also recommended that shatter proof goggles are worn, when removing installing and handling the
picture tube. People not equipped with the proper precautionary measures mentioned should keep the
picture tube away from body while handling.
6. As for a connector, pick and extract housing with fingers properly since a disconnection and improper
contacts may occur, when wires of the connector are led.
7. Use a proper screwdriver. If you use screwdriver that does not fit, you may damage the screws.
8. X-radiation precaution
This product contains critical electrical and mechanical parts essential for X-ray protection.
Normal anode voltage is 27.0 kV at zero beam picture tube current under AC 100-120V/220-240V input,
and anode voltage must not exceed the voltages shown below under any operation condition.
To measure anode voltage set brightness for very dim picture, and use a high impedance volt meter
between chassis and anode lead and measure high voltage.
If high voltage exceeds the specifications on the chassis schematic diagram, take the necessary
corrective action.
Table MAXIMUM ANODE VOLTAGE
beam current at 0 mA at 0.7 mA at 1.4 mA
A/B/R 34.5 kV 32.5 kV 32.3 kV
9. When you degauss the set with an external degaussing coil, you must keep strictly item “ * Notes about
degaussing method ” of ADJUSTMENT PROCEDURES.

Quick Start
To attach the MultiSync®FP Series monitor to your system,follow these instructions:
1. Turn off the power to your computer and MultiSync monitor.
If you are using the signal cable, continue to Step 2.
If you are using a BNC cable, please skip to Step 3.
NOTE: BNC cables may be purchased at your local electronics store.
2. For the PC: Connect one end of the 15-pin mini D-SUB signal cable to the connector of the display card in
your system (Figure A.1) and the other end to the back of the monitor (Figure A.2). Tighten all screws.
Proceed to Step 4.
For the Mac: Connect the Macintosh cable adapter to the computer (Figure B.1). Attach one end of the 15-pin
mini D-SUB signal cable to the Macintosh cable adapter (Figure B.1) and the other end to the back of the
monitor (Figure B.2). Tighten all screws.
Proceed to Step 4.
3. Connect the BNC cable to the appropriate connectors on the back of the monitor. Connect the red BNC cable
to the BNC connector on the monitor labeled R, the green BNC cable to the BNC connector labeled G (/Sync),
the blue BNC cable to the BNC connector labeled B. If you have a fourth BNC connector (Composite Sync),
connect it to the BNC connector on the monitor labeled HS/CS. If you have a fifth BNC connector (Vertical
Sync), connect it to the BNC connector on the monitor labeled VS (Figure C.1).
NOTE: Incorrect cable connections may result in irregular operation or damage display components.

4. Connect one end of the power cord to the MultiSync®FP Series monitor and the other end to the power outlet
(Figure D.1).
5. Turn on the monitor (Figure E.1) and the computer.
6. The Factory Setting for your monitor is set for D-SUB installation. If you are using a BNC cable connection,
push the BNC/D-SUB button on the front of the monitor (Figure E.1) to switch settings.
NOTE: If you have any problems, please refer to the Troubleshooting section of this User’s Manual.

sub-menu, press PROCEED.
Brightness/Contrast Controls
Brightness : Adjusts the overall image and background screen brightness.
Contrast : Adjusts the image brightness in relation to the background.
Degauss : Eliminates the buildup of stray magnetic fields which alter the correct scan of the electron
beams and affect the purity of the screen colors, focus, and convergence. When activated, your
screen image will jump and waver a bit as the screen is demagnetized.
Caution : Please allow a minimum of 20 minutes to elapse between uses of the Degauss
Control.
Size and Position Controls
Auto Adjust : Automatically adjusts the horizontal and vertical size and position settings for applicable
signal timings.
Left/Right : Moves the image horizontally (left or right).
