the map light consumes more power than the main R.A. drive motor. Operating the declination and focus motors
also draws more power from the battery, thus reducing the run time of the battery.
When taking your Ultima telescope to the southern hemisphere, there is a need to reverse the direction of the motors.
In previous telescopes this was accomplished by installing a reversed motor. Now, the direction the drive motor
moves the telescope is within the control of the user. Changing from northern hemisphere to southern hemisphere
requires changing the polarity of the drive motor. To do this:
1. With the power turned off, press down and hold the up and down buttons on the hand controller
simultaneously.
2. Turn the power switch on (keep holding the buttons down).
3. In one or two seconds the red (LED) will blink. This will indicate the telescope is set for the southern
hemisphere.
4. Keep the hand controller plugged in at all times. If you unplug the unit, it will default back to northern
hemisphere operation.
The direction of the drive motor is now reversed and will work in the opposite hemisphere. When you turn off the
drive, everything is reset. So, every time you turn on the drive in the Southern Hemisphere the motors must be set to
drive in reverse in this manner.
TROUBLE SHOOTING
When the battery is low, the LED that indicates the tracking rate will blink. At this point, about 20 percent of the
battery life remains. If the battery voltage gets low, either change the battery or plug the drive into an external power
source. An optional adapter allows the drive to run off of AC power (#18772) or 12-volt DC power (#18769).
If the battery is new, a blinking LED may indicate a mechanical problem. Call the Celestron repair department for
assistance.
