Working in Pulse mode with a detector:
For outdoor work under direct sunlight, or bright light
conditions, and for extended indoor ranges up to 40 meters,
use the Pulse mode with a detector.
When the pulse mode is activated, the laser lines will flash at
a very high frequency (invisible to the human eye). This will
allow the detector to detect the laser lines. The pulse mode
can be activated in both Automatic and Manual modes.
1. To turn the Pulse mode on , press the P button.
2. When activated, a slight reduction in laser line brightness
will occur.
3. To turn the Pulse mode off, press the P button again.
4. Laser lines brightness will return to previous brightness.
