5. Release R.A. Clutch Screw. Press the LFTT or RIGHT button on the hand controller to rotate
the polar scope to align the 12 o’clock position of the dial on the top, as shown in Figure 10. (Or
align to the zero position mark on the R.A. unit as shown in Figure 11). You may press number
9 button to change the rotation speed to MAX.
6. Make sure that the time and site information of the hand controller is correct. Press the MENU
button, then select “Align” and “Pole Star Position” to display the current Polaris position. For
example, on May 30, 2010, 20:00:00 in Boston, United States (Lat N42º30’32” and Long
W71º08’50”, 300 min behind UT, DST set to Y), the Polaris Position is 1hr 26.8m and r = 41.5m,
as shown in Figure 12 (a).
7. Adjust the mount in altitude (latitude) and azimuth (heading) direction to place Polaris in the
same position on the Polar Scope Dial as indicated on the HC LCD. In this case, the Polaris will
be located at a radius of 41.5’ and an angle of 1 hour 26.8 minute, as shown in Figure 12 (b).

You need to loose Azimuth Lock a little and use Azimuth Adjustment Knobs to adjust the mount
in azimuth (heading) direction (Figure 13). Unlock Latitude Clutch, and turn Latitude Adjustment
Screw or push the mount down to adjust the altitude (latitude), as shown in Figure 14. Secure
all the locks after the polar alignment is done.
Now the mount is polar aligned.
