Operating the laser
The laser distance meter consists of a laser transmitter and a laser receiver. The laser
distance meter determines the distance to a target by measuring the time it takes for a la-
ser pulse to reach the target and return to the laser receiver. This time is converted to a
distance, which is displayed on the screen.
The laser transmitter also works as a laser pointer. When the laser is on, you will see a
laser dot approximately at the target.
To operate the laser, do the following:
1. Enable the laser by selecting
