Operating Modes
The
cryo
ICE
BOX
operates in one of three modes: READY, FREEZE, and DEFROST. These modes are identified by the
system status indicator LEDs and the ablation status indicator LEDs located on the front of the
cryo
ICE
BOX
unit.
READY Mode
This mode is entered automatically upon successful execution of Power-on-self -test when the unit is first
turned on or following DEFROST Mode upon the
cryo
ICE probe reaching approximately 10
°C (50°F) and
automatically
venting. This indicates that the system is ready for the next cryo ablation run.
FREEZE Mode
This Mode is entered from the READY Mode when the user initiates the cryo ablation cycle by pressing
and releasing the Activation Switch or the Footswitch. In this mode, the N
2
O gas is allowed to cycle
through the
cryo
ICE probe causing a temperature drop to take place at the
cryo
ICE probe.
DEFROST Mode
This Mode is entered automatically from FREEZE Mode upon expiration of the ablation timer, or manually
by the operator when the Activation Switch or the Footswitch is actuated while in the FREEZE Mode. In
this mode, the
cryo
ICE probe temperature is actively forced towards the ambient temperature.
Once the
cryo
ICE probe temperature is above approximately 10
°
C (50
°
F), the
cryo
ICE BOX unit will transition back to
the READY Mode.
Note:
cryo
ICE
BOX
does allow early transition out from the DEFROST Mode into either the READY Mode or the
FREEZE Mode by pressing the Activation Button.
Note:
cryo
ICE
probe temperature may drop temporarily upon transition from DEFROST to READY state.
FAULT Condition
This is entered upon detection of any unrecoverable error condition during any Mode. The system
is inoperable in this Mode until the unit is first power cycled, and only if the fault condition no
longer exists or has been remedied.
