Release the RA Clutch Disk by tuning it counterclockwise (CCW) while holding the DEC
Mounting Bracket. Slowly move the camera/CW to horizontal position and balance the load in RA
direction by moving the CW in or out. More than one CW may be used. Return the mount to upward
position and lock the RA Clutch Disk again.
You can also remove the DEC Base from the short arm side of the DEC Mounting Bracket to
the long arm side (Figure 16a), or mount a ball head onto the DEC Camera Mounting Block (Figure
16b), or mount a ball head onto the DEC Mounting Bracket via Ballhead Mounting Screw 28 (Figure
16c).
