1/8" hex wrench into the notched-out section of the left-hand
fork arm. Tighten the hex-head nut located just inside the
notch.
CAUTION:In most instances only one turn of this hex-
head nut is required to fully retighten the Declination
lock.
6. Gauging the Movement of the Telescope
A common complaint of many first-time telescope owners is
that they cannot see the telescope "move" when the motor
drive is engaged. If fact, when the batteries are installed, the
power is on and the R.A. 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 difficult
to discern visually.
To check the movement of your telescope, look at an
astronomical object through the telescope's eyepiece with the
telescope polar aligned and with the motor drive on. If the
object remains stationary in the field of view, your telescope is
operating properly. If not, check to ensure that you have
engaged the R.A. lock and that the power switch on the control
panel is on. If the telescope is still not tracking, replace the
batteries.
7. Storage and Transport
When not in use, store your LX10 in a cool, dry place. Do not
expose the instrument to excessive heat or moisture. In
addition when the LX10 is to be stored for more than one
month, remove the 4 AA-size batteries from the power panel;
battery leakage may damage the telescope's electronic
system.
When transporting the telescope, take care not to bump or drop
the instrument; this type of abuse can cause the optical system
to misalign or cause damage to the electronic components.
8. Meade Customer Service
If you have a question concerning your LX10 telescope, call
Meade
Instruments Customer Service Department at
(949) 451-1450, or fax at (949) 451-1460. Customer Service
hours are 8:30AM to 4:30PM, Pacific Time, Monday through
Friday. In the unlikely event that your LX10 requires factory
servicing or repairs, write or call the Meade Customer
Service Department first,before returning the telescope to
the factory, giving full particulars as to the nature of the
problem, as well as your name, address, and daytime
telephone number. The great majority of servicing issues can
be resolved by telephone, avoiding return of the telescope to
the factory.
