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.
WA R N I N G :
•  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.

1. Turn all equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Ensure the cables are firmly inserted.
In the connections shown below, some cables may not be included with the projector (see Shipping contents 
on page 8). They are commercially available from electronics stores.
The connection illustrations below are for reference only. The rear connecting jacks available on the projector 
vary with each projector model.

							Connection 19
Many notebooks do not turn on their external video ports when connected to a projector. Usually a key 
combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled CRT/LCD 
or a function key with a monitor symbol on the notebook. Press FN and the labeled function key 
simultaneously. Refer to your notebooks documentation to find your notebooks key combination.
The D-Sub output only works when an appropriate D-Sub input is made to the COMPUTER 1 jack.
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 49 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. 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.
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.
