• How do I change the measurement unit on the LS1 Rangefinder?

  To switch units (m/in/ft), enter the setup mode by turning on the device and keeping the button pressed for 5 seconds. Navigate to Setup Page 2 to change the unit.

• What do the error codes D.E, T.L/T.H, and B.L mean?

  D.E indicates a measuring distance error (too close/far), T.L/T.H indicates ambient temperature is too low or high, and B.L indicates low battery voltage.

  Enter setup mode (long press 5 seconds) and go to Page 1. You can manually calibrate the rangefinder within ±7mm.

• Why is there no data displayed during measurement?

  This may be caused by a dirty laser receiving head or excessive shaking. Clean the lens and ensure the device is steady during use.
