1. Determine the installation location
CAUTION: Installing your LCD display must be done by a
qualified technician. Contact your dealer for
more information.
CAUTION:
MOVING OR INSTALLING THE LCD MONITOR
MUST BE DONE BY FOUR OR MORE PEOPLE
(LCD5220), BY TWO OR MORE PEOPLE
(LCD4020/LCD4620). Failure to follow this caution
may result in injury if the LCD monitor falls.
CAUTION: Do not mount or operate the display upside
down, face up, or face down.
CAUTION: This LCD has a temperature sensor and cooling
fan. If the LCD becomes too hot, the cooling fan
will turn on automatically. If the LCD becomes
overheated while the cooling fan is running, a
“Caution” warning will appear. If the “Caution”
warning appears, discontinue use and allow the
unit to cool. Using the cooling fan will reduce the
likelihood of early circuit failure and may help
reduce image degradation and “Image
Persistance”.
If the LCD is used in an enclosed area or if the
LCD panel is covered with a protective screen,
please check the inside temperature of the
monitor by using the “HEAT STATUS” control in
the OSD (see page 27). If the temperature is
higher than the normal operating temperature,
please turn the cooling fan to ON within the FAN
CONTROL menu within the OSD (see page 27).
IMPORTANT: Lay the protective sheet, which was wrapped
around the LCD monitor when it was
packaged, beneath the LCD monitor so as
not to scratch the panel.
2. Install the remote control batteries
The remote control is powered by two 1.5V AA batteries.
To install or replace batteries:
NOTE: If you do not intend to use the Remote Control for a
long period of time, remove the batteries.
3. Connect external equipment
(See pages 14-20)
• To protect the external equipment; turn off the main
power before making connections.
• Refer to your equipment user manual for further
information.
4. Connect the supplied power cord
