Operation Instructions
Measurement reference
When Initially turned on, the device default into the single measurement mode
in both directions; long press ( ) to turn off the left laser and long press (
)to turn off the right laser.
For bilateral lasers, with the marker laser as the reference.
Automatic switch to rear reference in case of one-way measurement
.
Note: After rebooting, the reference setting in last booting remains saved.
Two-way Measurement
Press the (MODE) button to enter Two-way single measurement mode ( ). Press
the measure button( ) after aiming at targets to get distances. The left side
length, right side length, and total length are displayed on the screen.
