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 .
