The pulselength in use is displayed at the upper left corner of the display. 
Appropriate pulselengths are preset to individual range scales. Therefore, you

pulselength setting, however, it is possible to change it for the ranges shown 
below. Generally, select a longer pulse for longer detection range and shorter 
pulse for better range discrimination.

3 nm, 3 sm, 6 km: Medium pulse, long pulse
