Yes. Please use "Epson Moverio Sensor Calibration". You can download and install it from Technical Information Site

In some circumstances, sensor calibration cannot be conducted inside buildings or near by those items with magnetic nature. In this case, please go outside, keep a distance from items with magnetic nature, and then try to conduct sensor calibration once again.

The sensors may be offset if you use them inside buildings or near by those items with magnetic nature. In this case, please use "Epson Moverio Sensor Calibration" to calibrate the sensors again.

If you calibrate the sensors when the LED indicators on the controller are flashing (charging or battery running low), the LED indicators may stop flashing and remain on. In this case, push the power button to turn your Moverio into sleep mode, and then push the same button to get it back. Afterwards, the LED indicators will resume flashing.
