All measurements are approximate and may vary from the actual sizes. If you want a permanent installation of the projector, we recommend that you 
use the actual projector to physically test the projection size, distance, and the projectors optical characteristics prior to the installation. This helps 
you determine the exact mounting position which best suits your installation.

source device as described below:
•  In the connection illustrations shown above, some cables may not be included with the projector (see Projector exterior view on page 13). They are 
commercially available from electronics stores.

Connecting a USB flash drive Connect a USB flash drive to one of the USB ports on the rear of the projector to view media files stored on the flash drive.
•  Some computers feature HDMI ports that do not transmit audio, in such cases a separate audio cable must be connected to the projector.
•  Many laptops do not turn on their external video ports when connected to a projector. Usually a key combination 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 laptop. Press Fn and the labeled function key simultaneously. Refer 
to your laptop’s documentation to discover your laptop’s key combination.
