• Rotate the nosepiece to move the objective to be replaced to the side.
• Unscrew the objective and remove it downward.
• Fix the new objective into the hole on the nosepiece. Be very careful to match
the threads correctly, the objective should screw in smoothly and easily.
Make sure the objective is screwed in tightly.
• If one of the nosepiece holes is not used for an objective a dustproof cap
should be screwed into the vacancy to prevent dust from entering. (Figure 6)
