Garmin 821P User Manual

When you’re done with your presentation, shut down the projector as 
described on page 41. Shutting down the projector correctly prevents 
premature lamp failure and possible damage from overheating.

If you have only one device connected to the projector, the projector 
should detect it automatically. If you have more than one device 
connected (for example, if you’ve connected both a computer and 
DVD player), you may have to switch between image sources. If you 
don’t see the image you want, press one of the following buttons on 
the remote control:
