+### Force Power Off
+
+In the event that a device becomes unresponsive, the device can be completely powered off by holding the power button for 10 seconds or more. The force-power-off method is hardware-based and will therefore work regardless of what firmware the device may be running.

+If the power state of a device is not known (for example, because a display may be malfunctioning) the device can be connected to USB. If one or more COM ports enumerate, the device is on (shown above). If no COM ports are seen, the device is fully powered off.

+Within the RTK Surveyor, two internal slide switches control the flow of NMEA data over Bluetooth and should be in the position shown above. If these switches get moved, the device will fail to correctly push NMEA data over Bluetooth. Placing a bit of tape over the top of the switches can help keep them in place.
