Paramount GEM User Guide

When the two-position switch (Figure 28) is in the balance position, the worm and gear
are separated, so the axis can rotate freely. When the switch is rotated to point at the
star (Track position), and the transport lock knob is in the unlock position, the mount is
ready for normal operation.
Notes:
• The transport lock knob is slightly recessed in the lock position.
• The transport lock knob should always be rotated clockwise when locking or
unlocking the axis.
For the Paramount ME, separate locking bolts must be installed to lock the axis in place.
See “Hour Angle Axis Locking Holes (Paramount ME Only)” on page 75 and “Declination
Axis Locking Hole (Paramount ME Only)” on page 95 for details about locking the
Paramount ME axes.
ADJUSTING THE PARAMOUNT’S MECHANICAL SWITCHES ALWAYS REQUIRES BOTH
HANDS!
Rotating the Two or Three Position Switch for both the RA axis and the Dec axis requires
the use of both hands to prevent sudden or unexpected rotation of the mount.
• Before rotating the Dec Axis Two or Three Position Switch with your right hand, firmly
grasp the Versa-Plate with your left hand to prevent sudden rotation of this axis from
an unbalanced payload.
• Before rotating the RA Axis Two or Three Position Switch with your right hand, firmly
grasp the Counterweight Shaft with your left hand to prevent sudden rotation of this
axis from an unbalanced payload.
When the switch is rotated to, or passes through the balance position, the axis will rotate
freely. Unexpected rotation of either axis due to an unbalanced payload can cause
personal injury or serious damage to the mount!
Always use extreme caution and please, always use BOTH HANDS!
Track Position: Rotate the arrow on the switch fully counterclockwise to engage the
worm with the gear. This position is used during normal mount operation.
Balance Position: Rotate the arrow on the switch to the center position to disengage the
worm from the gear so that the axis rotates freely.
Balancing either the hour angle or declination axis of the Paramount
always requires both hands!
