1. Set up a target with a clearly visible aiming point.
2. Mount your VIRIDIAN onto the weapon's accessory mounting rail (see Mounting procedures).
3. Turn ON your VIRIDIAN (see Switch Operation procedures).
4. While aiming the pistol through the iron sights, use one of the two provided adjustment wrenches to adjust the visible green point of your VIRIDIAN. Turn the windage and elevation wrench to superimpose your VIRIDIAN'S aiming point over the weapon's iron sight aiming point.
5. Aim and fire a three round shot group into the center of the target's aiming point.
6. Compare the impact point of the shot group to where your VIRIDIAN'S aiming point was on the target to ensure they line up.
7. Make the necessary adjustments to your VIRIDIAN to ensure its aiming point and the shot group are aligned.
8. Turn the unit OFF.

An alternative way to align your VIRIDIAN is to hold the green aiming point perfectly fixed to the center of the intended target and then adjust windage and elevation so that your green aiming point is brought to the center of your shot grouping. The gun and your Viridian must remain in a fixed position while making these adjustments.

Additional Helpful Guidelines for sighting your Viridian laser

Windage Adjustment
If your shot group is striking to the left of your intended target*:
Turn the windage adjustment CLOCKWISE to bring your shots more to the RIGHT
If your shot group is striking to the right of your intended target*:
Turn the windage adjustment COUNTER-CLOCKWISE to bring your shots more to the LEFT

Elevation Adjustment
If your shot group is striking above your intended target*:
Turn the elevation adjustment CLOCKWISE to bring your shots LOWER
If your shot group is striking below your intended target*:
Turn the elevation adjustment COUNTER-CLOCKWISE to bring your shots HIGHER
*as indicated by the visible green aiming point of your Viridian

General rule of thumb for Viridian windage or elevation adjustments
Every full 360° allen wrench turn will move your visible green aiming point approximately:

4 inches at a distance of 10 feet.
8 inches at a distance of 20 feet.
16 inches at a distance of 40 feet.

WARNINGS
Before handling any firearm with the VIRIDIAN, read and understand the entire contents of your firearm manual and the VIRIDIAN manual, especially the safety precautions and procedures for safe firearms handling.

Always check to see if the chamber of the weapon is empty or "clear" before attempting to mount or dismount the VIRIDIAN. Follow the "clearing" procedures as set forth in the manual for your firearm.

Be sure of your target and background before firing. When you squeeze the trigger, you must expect the pistol to fire and you must take full responsibility for firing it.

NEVER put your hand in front of the muzzle of a firearm. ALWAYS keep your finger away from the trigger until you are ready to fire. ALWAYS make sure the weapon is clear and on safe before making windage/elevation adjustments.

CAUTION
DO NOT FORCE WINDAGE AND ELEVATION SCREWS BEYOND THEIR INTENDED TRAVEL.
