The angle to the target also has an effect. Shooting to a target at a
90 degree angle (where the target surface is perpendicular to the flight path of the emitted energy pulses)
provides good range while a steep angle on the other hand, provides limited ranging. In addition, lighting
conditions (e.g. the amount of sunlight) will affect
the ranging capabilities of the unit. The less light (e.g. overcast skies) the farther the unit’s maximum range
will be. Conversely, very sunny days will decrease the unit’s maximum range.
Remove the battery cap with a coin by rotating the cap counter clockwise and insert a 3-volt lithium
battery into the compartment positive end first, then replace the battery cap.
