releasing the on/off switch on the hand piece cable. If using
the optional foot switch, press and release the on/off foot
switch.
Note: The radio frequency energy on/off switches function as
press-and-release switches. They are not designed to be held

Note: The lesion time is automatically set for 2:20 minutes.
When the lesion starts, the time decrements by seconds until
lesion time expires. Then, the radio frequency energy
automatically terminates.

the screen display (Figure 4-12), and monitor the various
outputs (eg, temperature, lesion time) during the procedure.

during the lesion. Immediately irrigate the urethra if it reaches
43° C, which automatically triggers a caution tone and
message; if the temperature reaches 47° C, the radio
frequency energy automatically shuts off. Failure to cool the
urethra can result in possible injury to the patient's urethra.

Warning: Do not continue treatment if a return electrode
error condition is detected. Ensure that the return electrode is
properly placed on the patient by monitoring user-interface

messages, and audible alarms. Take the appropriate action
from user interface message to correct any return electrode
problems. Otherwise, remove and replace return electrode
with new one. Continuing treatment with a faulty return
electrode connection can result in possible patient injury.
