Paramount GEM User Guide
66 | P a g e
This position is for balancing the payload and is the recommended position to place the
switch after the mount has been placed inside the shipping container box and while the
mount is being transported. If the mount is subjected to a severe impact during
shipping, both axes will rotate freely. Unrestricted motion in each axis can help minimize
damage to the worms and gears.
The Paramount must always be homed after balancing either axis!
Otherwise, the mount will be “lost in space” and potentially slew
beyond the mount’s slew limits.
Lock Position (Paramount MX only): Rotate the Three Position switch fully clockwise to
separate the worm from the gear and lock the axis in place. Always lock both axes before
lifting the mount.
An axis can be locked to any position, at 10-degree increments. Note that physically
rotating the switch to the lock position inserts an internal locking shaft into one of 72
locking holes that are machined into the internal gear. You will usually need to wiggle
the axis a few degrees back and forth to align the locking shaft with one of the locking
holes. When the shaft enters the hole, the entire Three Position Switch will drop slightly
into worm gear cover. Once locked, the axis can no longer rotate.
Rotating the switch away from the lock position causes the locking shaft to be removed
from locking hole and the axis will rotate freely. Note that the entire switch itself will
rise slightly out of the worm block cover as a result.
Unlock Position (Paramount MX and MYT): Pull out and rotate the transportation lock
knob 90 degrees clockwise to lock/unlock the axis. While this knob can be rotated in
either direction, always rotate it clockwise as counterclockwise rotation may cause the
knob head to become loose. Always lock both axes before lifting the mount.
Each axis can be locked at any position, in five-degree increments. Note that physically
rotating the switch to the lock position inserts an internal locking shaft into one of
seventy-two locking holes that are machined into the internal gear. You will usually need
to wiggle the axis a few degrees back and forth to align the locking shaft with one of the
locking holes. When the shaft enters the locking hole, the entire transport lock knob will
drop slightly into worm gear cover. The axis will not rotate when the knob is in the lock
position, even if the two-position switch is in the Track position.
Pulling out and rotating the knob 90 degrees allows the axis to rotate freely. Note that
the entire knob will rise slightly out of the worm block cover in the unlocked position.
