Introduction 12 Remote control effective range The remote control must be held at an angle within 30 degrees perpendicular to the projectors IR remote control sensor(s) to function correctly. The distance between the remote control and the sensor(s) should not exceed 8 meters (~ 26 feet). Make sure that there are no obstacles between the remote control and the IR sensor(s) on the projector that might obstruct the infra-red beam. Replacing the remote control batteries 1. To open the battery cover, turn the remote control over to view its back, push on the finger grip on the cover and slide it up in the direction of the arrow as illustrated. The cover will slide off. 2. Remove any existing batteries (if necessary) and install two AAA batteries observing the battery polarities as indicated in the base of the battery compartment. Positive (+) goes to positive and negative (-) goes to negative. 3. Refit the cover by aligning it with the base and sliding it back down into position. Stop when it clicks into place. • Avoid leaving the remote control and batteries in an excessive heat or humid environment like the kitchen, bathroom, sauna, sunroom or in a closed car. • Replace only with the same or equivalent type recommended by the battery manufacturer. • Dispose of the used batteries according to the manufacturers instructions and local environment regulations for your region. • Never throw the batteries into a fire. There may be danger of an explosion. • If the batteries are dead or if you will not be using the remote control for an extended period of time, remove the batteries to avoid damage to the remote control from possible battery leakage. • Operating the projector from the front Ap p rox. + 30 º • Operating the projector from the top Ap pr ox. +30 º Downloaded From projector-manual.com BenQ Manuals

Connection 17 • If you wish to use this connection method when the projector is in standby mode, make sure the Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See Standby Settings on page 46 for details. Connecting video source devices You need only connect the projector to a video source device using just one of the connecting methods, however each provides a different level of video quality. The method you choose will most likely depend upon the availability of matching terminals on both the projector and the video source device as described below: Connecting audio The projector has built-in mono speaker(s) which are designed to provide basic audio functionality accompanying data presentations for business purposes only. They are not designed for, nor intended for stereo audio reproduction use as might be expected in home theater or home cinema applications. Any stereo audio input (if provided), is mixed into a common mono audio output through the projector speaker(s). The built-in speaker(s) will be muted when the AUDIO OUT jack is connected. • The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See Connecting audio on page 17 for details. • If the selected video image is not displayed after the projector is turned on and the correct video source has been selected, check that the video source device is turned on and operating correctly. Also check that the signal cables have been connected correctly.
