My TSC1 no longer turn on. When I try to turn on the TSC1 datalogger – the screen lights up for a moment and then disappears. Please give me any idea to restore this device.

Answer

You can try to power it up using external power.  If that doesn’t work then a forced format may  help, but will certainly clear all data stored including Geoids, feature code libraries, etc.  This can be preformed by powering the unit down. Then press and hold Fn & F5, power the unit up then continue holding the Fn and F5. If there is no response then the data collector is probably broken.
