Step 3: Download the autorun.brs file from this link [autorun.brs]
Step 4: Insert the SD card into the player.

* If too much time elapses the BrightSign player will apply an internal update and eventually display the BrightSign web setup page. If this happens, just power off the player, and proceed like normal. Do not power off the player if the internal update has started, wait until the web setup page is loaded before powering off.
