Once you have assembled your telescope and aligned the equatorial mount with the North Star (see "Understanding the

Equatorial Mount" section), you can begin enjoying the benefit of the Automated Tracking System. The functions of the

system are outlined below:

AUTOTRACK--By pushing this button, you activate the Automated Tracking System and your telescope begins to move

with the night sky.  Push and hold this button to turn the unit off. The default motion is set for the Northern Hemisphere.

FWD/REV (FORWARD/REVERSE)--By pushing this button you automatically reverse the direction of the Automated

Tracking System. This can be used to switch tracking direction for the Southern Hemisphere or to back up the telescope

in its tracking motion.

SPEED--The speed buttons (UP AND DOWN) will increase the speed in the direction of tracking or decrease the speed

in the direction of tracking.

LED INDICATOR--The green LED light on the ATS when lit indicates that the ATS is operating. When fresh batteries are

required, the green LED will change to red.

The ATS requries a 9-volt alkaline battery (user-supplied). To install or replace, simply remove the battery door located

under the Bushnell logo, attach battery to clamps, and replace battery door.

NOTE:  PROPER ALIGNMENT OF THE EQUATORIAL MOUNT AND FRESH ALKALINE BATTERIES WILL ENSURE

THE BEST AUTOMATED TRACKING SYSTEM SUCCESS.
