Install Batteries: Insert eight (user-supplied) D-size batteries into the battery
holder, oriented as shown in the diagram on the battery slots of the holder. Plug
the batter
y pack into the 12v DC connector (
B,
Fig. 1e
) on the computer control
panel. See
Fig. 12.
Caution: Use care to install batteries as indicated by the battery com-
partment. Follow battery manufacturer's precautions. Do not install bat-

13. Remove Plastic Strip from Reticle LED: The polar alignment reticle LED (30,
Fig. 1d
) contains two watch batteries. The reticle's LED is shipped with a plastic
strip between the two batteries to protect battery life. Unthread both the cap (
E).
Remove the plastic strip before using. Refer to the reticle assembly in
Fig. 13b and
note the orientation of the batteries. Place the batteries (
C) into the battery holder
(
D) before inserting into the reticle container (A).
Note: Remember to turn off the LED when you are not using the reticle.

Balancing the Telescope
In order for the telescope to be stable on the tripod and also for it to move smoothly,
it m
ust be balanced.
T
o balance the telescope, unlock the Right Ascension or R.A. lock
(
33, Fig. 1d). When this axis is unlocked, the telescope pivots on the R.A. axis. Later
in the procedure
, y
ou will also unloc
k the Declination or Dec.
lock (
17,
Fig.
1d)
.
When
unlocked, the telescope pivots on the Dec. axis. Most of the motion of the telescope
takes place by moving about these two axes, separately or simultaneously. Try to
become familiar with these locks and observe how the telescope moves on each axis.

1. Firmly hold the optical tube secure so that it cannot accidentally swing freely.
Loosen the R.A.

along the counterweight shaft until the telescope remains in one position without
tending to drift down in either direction. Then re-tighten the counterweight lock
knob, locking the counterweight in position.
