PC Display (F) Keys
Toggle between the different presentation modes by pressing both the Fn and specific F key at the same time slowly until you find a suitable display option. Computers typically have three presentation modes which cycle from the laptop screen only, the projector only or both simultaneously.
- The Fn key - located between the "Ctrl" and "Alt" keys
- The Display Function (F) key - located among the top row of keys labeled as either "CRT/LCD" or has an icon of a monitor (see photo for variations)
NOTICE: If the computer will not display, try restarting it while plugged into the AV system.
Computer (or iPod) Audio
The small cable attached to each end of the VGA cable is used to play audio (see photo above). Plug one end of the cable into the headphone port on your computer (or iPod) and the other end into the audio input next to the VGA input on the control panel.
The volume control is on the AMX touch panel. There is also a "mute" button next to the volume slider. The volume on the computer (or iPod) must also be turned up.
VGA Cable Location
The VGA cable is located on a hook on the black box. If the cable is not there, locate the cubbyhole within the black box. To open the cubbyhole, press the latch down while pulling towards you.
Signs of a broken VGA cable - pins appear bent or displayed image has noticeable color tint.
