Press and hold to decrease sound. 14 12 15 Battery Installation and Replacement The remote control is powered by two 1. 5V AA batteries. Press down on the battery compartment grip and slide the compartment in the direction of the arrow. Install the two new batteries, making sure that their polarity matches the (+) (-) diagrams inside the battery compartment. Close the battery compartment cover. Remote Control Cautions · Do not drop or mishandle the remote control unit. · When not using the remote control unit for a long period, remove the batteries. · Do not use new and old batteries together, or use different types of batteries together. · Do not take apart the batteries, heat them, or throw them into a fire. STANDBY /POWER POWER Operating Range · The infrared signal operates by line-of-sight up to a distance of approximately 22 feet/7 m and within a 60 degree angle of the remote sensor of the monitor. · The monitor will not function if there are objects between the remote control and the sensor or if strong light falls on the sensor. Weak batteries will also prevent the remote control from properly operating the monitor. 30 30 DEGAUSS POWER ON OFF RGB 2 PROCEED EXIT VIDEO 1 VIDEO 2 RGB 1 POSITION / CONTROL SCAN WIDTH HEIGHT SIDE PIN NORMAL NORMAL BRIGHT CONTRAST MUTE VOLUME MULTIMEDIA MONITOR RD-346E 79644641 16 13 17 Functions of DIP SW SHORT ON Set the No. 1 pin to the ON/SHORT position when sync on green signals are necessary for synchronization with an external component.

Control, Intelligent Power Manager, External control, wireless control, and OSM control. To change a switch setting use a pointed object, such as a pen or pencil, to push the switch to the desired position.
