Mounting the Telescope
5
On the tripod, loosen the latitude control knob
and lift up the tilt-plate so that you can easily access
the underside of the plate. Relock the latitude control
knob, so the assembly doesn’t slip while you are
attaching the telescope.
Take the ETX90 from its packaging and line up the
mounting holes on the base of the telescope with the
tripod attachment knobs. Thread both attachment
knobs into the base of the telescope. Tighten to a firm
feel only.
Unlock the latitude
control knob and
lower the tilt-plate
until it is level (push
the tilt-plate down
until it stops; this is
the level position).
Lock the latitude
control knob.
Installing the Batteries
6
Lift the battery cover. Gently remove the battery
holder from the compartment so you don’t accidentally
pull out the wires attached to the holder. Insert 6 user-
supplied “AA” batteries in the holder. Refer to the
diagram on the holder to orient the batteries properly.
Replace the holder back into the battery compartment
and replace the lid.
CAUTION:
Use care to install batteries as indicated by
the battery compartment. Follow battery manufacturer’s
precautions. Do not install batteries backwards or mix
new and used batteries. Do not mix battery types. If
these precautions are not followed, batteries may
explode, catch fire, or leak. Improperly installed
batteries void your Meade warranty. Always remove
the batteries if they will not be used for a long period
of time.
Secure Vertical and Horizontal Locks
7
Tighten (to a “firm feel” only, do not overtighten)
the vertical lock (6) and the horizontal lock (9). See
pages 13-16 for more information.
