4.1 Preparation for Use
Prior to using the Visual-ICE System, inspect the chassis, power cord, brake, safety cables, gas
supply lines, gas connections, and the monitor touch screen to ensure they are not damaged. If any
of the components are damaged, contact Galil Medical Customer Service.
CAUTION. If condensation is present on the system, allow the system to dry completely for 12
hours prior to powering up the system. Powering up the system with condensation could result in
permanent damage to the electrical boards, causing the system to be inoperable.
Before the patient is anesthetized, set up the Visual-ICE System, connect the gas cylinders, and
conduct functionality tests on each cryoablation needle and thermal sensor (reference Section 4.1.4).
