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.

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.

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.

•Do not mix battery brands.

•Do not combine new and old batteries. This can shorten battery life or cause liquid leakage of batteries.

•Remove dead batteries immediately to prevent battery acid from leaking into the battery compartment.

•Do not touch exposed battery acid, it may injure skin.

4. Connect the supplied power cord
