(Optional) Light Path Setup

}If it is required to mount a reflected light filter, mount it immediately after the following operation. (See next section.)

1. Loosen the clamping screws on the top cover @ using the Allen screwdriver (2 mm), and remove the top cover.

2. Turn the light path selector knob ² counterclockwise to remove it.

(This knob should be retained by the user because it will be reused when restoring the light path switching stroke to the

original setting.)

3. Using the Allen wrench (3 mm), remove the four clamping screws (AB4 x 16 ) | of the observation light path unit ³, take

out the unit ³ and place it upside down.

4. Loosen the mirror unit clamping screw ƒ using the Allen screwdriver, insert the desired mirror unit ... into the mount

dovetail (so that the product name on the side of the unit is upside down), and tighten the clamping screw ƒ.

5. Using the Allen wrench (3 mm), remove the screw † limiting the light path selection stroke.

(This screw should be retained by the user because it will be reused when restoring the light path switching stroke to the

original setting.)

6. Attach and clamp the observation light path unit ³ in the original position, and also clamp the top cover @.

# To clamp the observation light path unit ³, use the Allen wrench (3 mm) because this enables surer clamping

than the Allen screwdriver.

7. Screw the provided longer light path selector knob firmly into the position for the knob ².
