15 Battery Installation and Replacement The remote control is powered by two 1.5V AA batteries. 1. Turn the remote control unit upside down. Press down on the battery compartment grip and slide the compartment in the direction of the arrow. 2. Install the two new batteries, making sure that their polarity matches the (+) (-) diagrams inside the battery compartment. Incorrect polarity could damage the remote control unit. 3. Close the battery compartment cover.
17 Set the No. 1 pin to the ON/SHORT position when sync on green signals are necessary for synchronization with an external component.

23 Daisy-chaining Your monitors The REMOTE IN/OUT terminals allow you to control monitors by one remote control. NOTE: The connection of three XP37 Plus/XM37 Plus monitors or more with THROUGH OUT (VIDEO 1 or 2) terminals may degrade image quality. To do so: When using the VIDEO inputs: THROUGH OUT (VIDEO 1) Connections 1. Connect THROUGH OUT 1 BNC or S-VIDEO 1 OUT to external components to relay the signal input at VIDEO 1 IN(BNC-type), or S-VIDEO 1 IN. 2.
25 External Speaker Connections External speakers may be connected to the monitor to reproduce sound from VIDEO 1, VIDEO 2, RGB 1 or RGB 2 signal sources. External speakers may be connected directly to the EXTERNAL SPEAKERS terminals or indirectly by connecting a stereo system amplifier to the audio outputs. If non-shielded speakers are used, they must be located a minimum of 4 feet away from the monitor. SPEAKER SELECT INT EXT Right 4 ft. 4 ft.
27 Operation Power This section describes how to select a computer or video source and how to adjust the picture and sound. General Controls Before you turn on your MultiSync XP37 Plus/XM37 Plus monitor ensure that the computer or video source is turned on. 1)To adjust: 1. Turn On The Monitor The power button is on the front panel of the monitor. By turning this switch on, the STANDBY/POWER indicator will turn to green and the monitor will become ready to use. OSM is also usable from the rear panel.
29 Direct Control Screen You can adjust the raster, visual and sound using the direct key on the remote control.

43 Command Communication Sequence When external equipment such as a personal computer gives the command to the XP37 Plus/XM37 Plus, the XP37 Plus/XM37 Plus returns an ACK. So make sure that the external equipment receives this ACK. Command sending/receiving sequence Command External equipment (PC) XP37 Plus/XM37 Plus ACK The XP37 Plus/XM37 Plus returns an ACK if it has received the command correctly. If it has not received the command correctly due to data error, it will return nothing.
45 Troubleshooting Before arranging for service by the NEC Service Center, check the following to be sure repairs are needed. Possible Cause Problem No Picture or Sound Power cord unplugged. Plug in power cord. Power outlet inactive. Be sure wall switch is on and outlet has power. Switch to ON or connect to an active AC outlet. Power of external equipment is not ON. External equipment has been incorrectly connected. Sound OK; poor picture with VIDEO signal input.
