The following suggestions may be helpful with operation
of the LX80:
The power indicator light on the telescope does not
come on or there is no response when pressing
the AudioStar Arrow keys:
• Verify that the Computer Control panel power
switch (Page 10, Fig. 3. C) is in the ON position.
• Verify that the AudioStar coil cord is fi rmly
connected to the HBX port (Page 10, Fig. 3, D).
• If using internal power (batteries), verify that the
batteries are installed correctly and that they
have suffi cient charge (see GETTING STARTED,
Page 15).
Note: If the batteries are getting low on charge,
there will be a marked difference in the slew
speed. The speed indicator lights may also
fl ash and the speed may change. If any of these
symptoms occurs, turn the power off and replace
the batteries.
• If using an external power source, verify that it is
properly connected between the 12-volt connector
and wall plug (AC source) .
• If AudioStar does not respond to commands, move
the power switch to OFF and then back to ON.
• If the telescope does not slew after power is applied
or if the motor quits or stalls, verify that there are no
physical obstructions that would impede telescope
movement.
• If all physical obstacles are removed and the
telescope still does not move properly, turn off the
power and unplug AudioStar. Plug AudioStar back
in and turn the power back on.
• Verify that both axes are properly balanced
Unable to see an image through the eyepiece:
• Confi rm that the lens cover has been removed
from the telescope.
• Verify that the telescope is pointed and focused on
an object. Adjust the focus until the image appears
and is sharply in focus.
•Object appears in the viewfi nder but not in the
eyepiece:
• The viewfi nder is not properly aligned with the
telescope (see Aligning THE VIEWFINDER,
when the motor drive is engaged. In fact, when the
batteries are installed, the power is on and the RA
lock engaged, the telescope is moving. However, the
movement is at the same speed as the hour hand of
a 24-hour clock; as such, the movement is diffi cult to
discern visually.
To check the movement of your telescope, look at an
astronomical object through the telescope’s eyepiece
with the telescope aligned and with the motor drive on.
If the object remains stationary in the fi eld of view, your
telescope is operating properly. If not, check to ensure
that you have engaged the RA and DEC lock and that
the power switch on the control panel is on. Also check
if “Astronomical” is selected in the “Targets” option of
the setup menu.
