			* Make sure the grey trigger cable is connected firmly.
			** If you replug the cable, it is recommended that you also close out your task program. Plug the cable back in, then restart the program. Some software will run a check on all connected devices upon startup, so if you replug a cable while it's already running, it may not detect the connection.

Remember, do NOT bring the demo button box from the testing room into the scanner room--it is NOT MR safe.		* If one or more buttons are still not responding, ask the MR Tech for another box.

Sometimes, if the coils aren't plugged in correctly or if the scanner has been working continuously for a long time, unusual things will happen during your protocol. These issues may include your scan not starting or acquisition stopping mid-sequence with strange activity on the bore screen.

	In ~~these~~ cases, it may be necessary to reboot the system (and in fact, restarts are conducted regularly outside of operating hours to keep data acquisition running as smoothly as possible). Before restarting the whole system, however, first determine if your issue can be resolved by other methods.

			* Make sure that the correct input option is selected on the AV box.
			** Look at the front panel of the black box on the control room desk. Check that the light to the RIGHT of the input you want (DisplayPort, HDMI, etc.) is lit orange. If not, simply press the correct button.
			* Try another cable. If you usually use DisplayPort, you can try HDMI, or vice versa.
			* Try an(other) adapter. There are several in the box by the window (please return whatever you use to the box when you're done).
			* If you usually duplicate displays, try extending. Certain laptops and/or programs are susceptible to crashing in mirror mode specifically.
			* Reset the AV box. At the leftmost edge of the front panel of the box, there is a power button. Press it once to turn off, then again to turn back on.
