Y-Axis On/Off
The Y-axis can be turned off to produce pure X-axis travel. This results in a mode that may be
preferred for difficult injections/transfers, or when the cell or egg is more sensitive to the
withdrawal of the pipette.
1.4.2.3
Z-Axis Control
Movement of the micromanipulator in the Z-axis (vertical) is achieved by rotating the control
on the end of the joystick. Looking down on the joystick from above, and using the default
axis settings, a rotation of the Z-control in a clockwise direction will cause the
micromanipulator to move downwards. A counterclockwise rotation will result in an upward
movement of the micromanipulator.
1.4.2.4
Joystick Declutch Mechanism
The electronic link between the joystick and the manipulator mechanical can be disconnected
temporarily in order to reposition the joystick without affecting the position of the
micropipette. This declutch function is achieved by touching the joystick just above the
rubber handgrip - the X and Y movement will remain deactivated for as long as your finger is
touching the band. The link is reestablished by releasing the touchpad. See Operating
Instructions for more details on how to use the declutch.
1.4.2.5
Height Adjustment
To maintain good ergonomics and operator comfort, the height of the joystick can be
adjusted, as shown in the figure below. The bottom of the joystick can be placed anywhere
from zero to 45 mm above the black hand-rest pad. The adjustment is made by first loosening
the black locking knob located on the front of the joystick column. Move the joystick
assembly up and down along its vertical track until a comfortable position is achieved, and
then lock the position by tightening the locking knob.

1.4.2.6
Joystick Tension Ring
There is a friction mechanism in the top of the joystick assembly allowing the X-Y movement
of the joystick to be adjusted for comfort and feel. The friction is reduced by rotating the
black dial clockwise (looking down from above) and increased by rotating counterclockwise.
