Please see attached instruction manual for the LRA MV3
Factory reset: During “Shooting Mode,” (allow the Send it to fully power on and begins sensing level) turn the power knob up and down quickly (without powering the unit off ) until you see the two outside LEDs (Blue/Red) flashing (approximately 5-6 cycles). The unit will flash from the 2 outside LEDs to the next 2 LEDs with the final Green LED flashing. Once the Green LED starts to flash turn the power knob up and down (as previously stated) until the two outside and Green LED’s turn on together, wait until the 3 LED’s transition off and the unit resets as if it were powered up as normal. The Send iT is now reset to the factory settings and calibration.
