The saline tubing is being moved by the saline pump. How can I
stop it?
• Lower the rear tubing guide so that it stops the saline tubing from advancing
without crimping the saline tubing.
• Use only saline tubing from ACIST Medical Systems. e performance of
other tubing cannot be guaranteed.
Why is the hand controller not working?
• Check for kinks in the hand controller tubing.
• Make sure that the luer connections on the hand controller are securely
fastened to the control panel. e control panel can be rotated up for a
better view of the luer connections. If the hand controller is disconnected,
reconnect and recalibrate by pressing CALIBRATE HC on the control panel.
• e hand controller must be replaced. Connect a new hand controller and
recalibrate by pressing CALIBRATE HC on the control panel.
The saline button on the hand controller is not working. Why?

fastened to the control panel. e control panel can be rotated up for a
better view of the luer connections.
• If needed, reconnect the hand controller. Two to three turns are needed to
make a good connection. If the hand controller is reconnected, calibrate it
again.
• Make sure that the saline pump is closed and the rear tubing guide is
lowered onto the saline tubing.
