Attaching the XY Dot Finder to the telescope tube
1) Loosen the finder bracket fixing screw fully to allow insertion of the dovetail mounting
block of the XY Dot Finder unit.
2) Attach the XY Dot Finder to the telescope as shown in the figure 2, tighten the finder
bracket fixing screw securely (The mounting block is made of plastic and over tightening the
fixing screw may cause damage.).

3) Unfasten the alignment clamp by turning counter-clockwise and set the finder body
roughly in parallel with the telescope tube. Then, fasten the alignment clamp by turning
clockwise.
4) Choose a conspicuous target in the distance and place the target in the center of the field of
view of the telescope at low power.
Please read the instruction manual supplied with the telescope to understand how to align the finder
scope.
Adjusting and Aligning the XY Dot Finder
1) Activate the red dot by turning the brightness dial to clockwise. The brightness of the red
dot can be adjusted freely by turning it to obtain brightness suitable for viewing.
The red dot goes off when the dot marked on the brightness dial is aligned with the dot on the finder
body.
2) Confirm the red dot can be seen in alignment with the sight line and the guidepost in the
lower middle of the zero-power objective lens. Then, point the red dot toward your target
object as you look through the telescope in order to align the field of view of the XY Dot Finder
with the field of view of the telescope.

The red dot comes into focus when you view infinity.
3) Position the red dot by using the fine adjustments, which can move the finder in vertical
and horizontal directions independently. Place the target and the red dot so they overlap
each other.
4) After you finish the alignment, turn off the red dot by turning the brightness dial
counter-clockwise until it clicks.
Now the XY Dot Finder is ready for use. Turn on the red dot when you begin your observing
session.
Do not force the brightness dial. This may damage your adjustments for alignment.
Replacing the Battery
The XY Dot Finder comes with the CR2032 battery.
1) Make sure that the brightness dial is in off position. Open the top battery container cover
by turning counter-clockwise while holding down the brightness dial as shown in the figure 1
right.

2) Push down the rim of the battery to squeeze out the battery from the battery container.
Remove it and replace with a fresh battery.
3) Put the battery container cover back in place and close it.
Using the XY Dot Finder in the daytime (e.g. Digi-scoping) exhausts the battery very quickly as the red
dot is apt to be set at its maximum brightness. Carry an extra battery, just in case.
Attaching the Low-profile Finder-base (at your option)
The low-profile finder-base has a 1/4-20 thread for general use.
1) You will need the low-profile finder-base and a Phillips screw driver together with the XY
Dot Finder. (The mounting block is preset to the XY Dot Finder at Vixen’s factory as shown
in the figure.)

2) Loosen the two screws on the side of the finder body to detach the finder bracket from the
XY Dot Finder. (The finder bracket can be removed with a back and forth slide motion as you
loosen the screws.)
3) Attach the low-profile finder-base on the back of the finder body and tighten the two screws
securely. (The low-profile finder-base has a front and rear, but you can attach it either way
according to your needs.)
4) This XY Dot Finder is not compatible with the previous Vixen Dot Finder models.
Tips on using the XY Dot Finder
Loosening the alignment clamp will allow you to turn the XY Dot Finder to 180 degrees
laterally. This may facilitate your viewing through the eyepiece if the alignment clamp causes
interference. Please change the orientation of the alignment clamp if this is the case.
