English Installation This device cannot be used or installed without the Tabletop Stand or other mounting accessory for support. For proper installation it is strongly recommended to use a trained, NEC authorized service person. Failure to follow NEC standard mounting procedures could result in damage to the equipment or injury to the user or installer. Product warranty does not cover damage caused by improper installation. Failure to follow these recommendations could result in voiding the warranty.
Attaching Mounting Accessories 2. Installing and removing stand The display is designed for use with the VESA mounting system. CAUTION: Installing and removing the stand must be done by two or more people. 1. Attach Mounting Accessories How to install stand 1. Please turn monitor off. Mounting accessories can be attached while the monitor is on the Tabletop Stand in the upright position (Figure 1). Be careful to avoid tipping monitor when attaching accessories.
When using the display with the Tabletop Stand fasten the LCD to a wall using a cord or chain that can support the weight of the monitor (approx. LCD4020: 31.1 Kg/LCD4620: 37.9 Kg) in order to prevent the monitor from falling. Fasten the cord or chain to the monitor using the provided clamp and screw. Screw Holes LCD4020: 250mm/LCD4620: 210mm Cord or chain Clamp Screw Before attaching the LCD monitor to the wall, make sure that the wall can support the weight of the monitor.
Setup 1. Determine the installation location NEC recommends the following battery use: CAUTION: Installing your LCD display must be done by a qualified technician. Contact your dealer for more information. • Place “AA” size batteries matching the (+) and (-) signs on each battery to the (+) and (-) signs of the battery compartment. • Do not mix battery brands. • Do not combine new and old batteries. This can shorten CAUTION: MOVING OR INSTALLING THE LCD MONITOR MUST BE DONE BY TWO OR MORE PEOPLE.
11. Recommended Adjustments • Remove the six screws (Figure 4). • Use 6 of the M4 x 10 screws (included) to attach the cable cover (Figure 5). To reduce the risk of the “image persistence”, please adjust the following items based on the application being used: “SCREEN SAVER”, “SIDE BORDER COLOR” (See page 27) “DATE & TIME”, “SCHEDULE SETTINGS” (See page 25). It is recommended that the “FAN CONTROL” setting (See page 27) be turned to ON also. Figure 4 Figure 5 6.

NOTE 2: IMAGE PERSISTENCE Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed.
MONITOR ID and IR CONTROL Using one PC or one infrared wireless controller, up to 26 individual LCD4020/LCD4620 monitors can be controlled through a daisy chain via RS-232C connection. 1. Connect PC and LCD4020/LCD4620. Connect a PC’s RS-232C control output to the LCD4020/LCD4620’s RS-232C input. You can then connect the RS-232C output from the LCD4020/LCD4620 to another LCD4020/LCD4620’s RS-232C input. Up to 26 monitors can be connected using RS-232C. 2. Set Monitor ID and IR Control mode.
Controlling the LCD monitor via RS-232C Remote Control This LCD monitor can be controlled by connecting a personal computer with a RS-232C terminal.
