Remove the blue circle screws and remove the base. ※ Check the connection of the circuit board connector. Plugging and unplugging while powered on can cause malfunctions. ⑤ Unscrew the lens counterclockwise. ※ If the screw lock adhesive is strong, make a scratch around the screw with a cutter and turn it with pliers. ⑥ Attach the base, and use the narrowest part of the positioning jig's 3 sides to tighten the gap between the lens and the base to a loose fit. ※ Be careful not to overtighten (damages the light-receiving sensor). Refer to Note 1 for focus adjustment. After adjustment, reassemble in the reverse order. § Supplementary Note 1 From the position where the lens is attached with the jig, gradually loosen it by turning it to the left while searching for the adjustment point. Be careful not to damage the light-receiving sensor. A subject with a clear pattern of light and dark is recommended. ※ If focus adjustment is difficult (be careful of short circuits and static electricity)… Insulate the back of the lens circuit board with masking tape, etc., and connect the wiring in step 2. While looking at (or having someone look at) the screens of the sub-unit and main unit, turn the lens to adjust. After adjustment, disconnect the connection in step 2 and reassemble. § Other Please contact us via transaction messages if you have any questions.
