- With the device powered on, locate the 'MODE' button (if separate from the power button).
- Press and hold the 'MODE' button for a few seconds until the unit changes (e.g., from 'F' for feet to 'Y' for yards or 'M' for meters).
- Release the button when your desired unit is displayed.
6. Maintenance
6.1 Cleaning the Lenses
