Directions for use
Return device to initial factory condition
Returning your device to its initial factory condition erases everything from the device,
including patient information, test results, and settings. To do a "factory reset", you
need to do both "Erase everything" and "Reset settings".
1. Power on the device and ensure that the device is charged.
2. Scroll to Settings > Memory > Erase everything.
A confirmation screen appears asking if you want to erase everything.
3. If you do not want to erase everything, scroll left to select No, and press the
joystick.
4. To erase everything, press the joystick to select Yes.
CAUTION Results deleted on the device cannot be recovered. Save the
results you want to keep on a computer or laptop before deleting them
from the device.
