BATTERY ACCESS INSTRUCTIONS
The StarPointer finderscope is powered by a long life 3V lithium battery (#CR2032) located directly under the StarPointer’s front end
(Figure 2-15).
NOTE: Before using the StarPointer, remove the protective plastic cover over the battery.
To access the battery compartment, turn the StarPointer upside down. Using a Phillips head screwdriver, loosen the screw and lift
up the battery cover and remove the small plastic protector. When replacing the battery, make sure to install the new battery with
its positive terminal (+) facing outward. If the telescope will not be in use for a long period of time, it is recommended to remove
the battery from the StarPointer.
WARNING: KEEP BATTERIES OUT OF REACH OF CHILDREN.
Examine devices and make sure the battery compartment is correctly secured, e.g. that the screw or other mechanical fastener is
tightened. Do not use if compartment is not secure.
Dispose of used button batteries immediately and safely. Flat batteries can still be dangerous.
Tell others about the risk associated with button batteries and how to keep their children safe.
ALIGNING THE STARPOINTER FINDERSCOPE
1. Take the telescope outside during the day. Using your naked eye, find an easily recognizable object, such as a streetlight, car license plate,
or tall tree. The object should be as far away as possible, but at least a quarter mile away.
2. Remove the main dust cover from the telescope and make sure your lowest power (longest focal length) eyepiece is installed in the focuser.
3. Move the telescope left and right or up and down so that it is roughly pointing toward the object you chose in step 1.
4. Look through the telescope using the eyepiece and manually move the telescope until the object you chose lies in the center of the view. If
the image is blurry, gently turn the focus knobs until it comes into sharp focus.
5. Once the object is centered in your eyepiece, turn on the finderscope by turning the power switch knob clockwise as far as it will go.
6. With your head positioned about a foot behind the finder, look through the round window and locate the red dot. It will probably be close to,
but not on top of, the object you see when you are looking through the eyepiece.
7. Without moving the telescope, use the two adjustment knobs on the side and underneath the StarPointer. One controls the left-right motion
of the dot, while the other controls the up-down motion. Adjust both until the red dot appears over the same object you are observing in the
eyepiece.
Now choose some other distant targets to practice aiming your telescope. Look through the StarPointer window and place the red dot on the
target you are trying to view and verify that it is in the eyepiece of the scope.
NOTE: Be sure to turn off the StarPointer finderscope when not in use to conserve battery power. New batteries can be purchased online or
at watch/electronic stores.
