CAUTION: The cervical collar must be fully retracted to its proximal
position in order to minimize the potential for damage to the sheath
when closing the array.
2.39 Unlock the disposable device by pressing the lock release button.
Close the disposable device by holding the front handle stationary
and gently pulling the rear handle backwards until the closed array
indicator, located at the hinge of the front and rear handles, reads
"ARRAY CLOSED". This indicates that the array has been retracted
into the sheath and the disposable device is in the closed position.
(See step 2.18.)
NOTE: If it is difficult to close and remove the disposable device,
see the Troubleshooting section, "Difficulty closing and removing
the disposable device post-ablation."
CAUTION: To avoid damaging the device, employ gentle technique
when retracting the array.

biohazardous waste and disposed of according to standard
practices of the hospital or clinic where the treatment is
performed.
2.43 Discharge the patient from the hospital or office as indicated
by the managing physician.
Periodic Maintenance and Service
There is no service manual for the NovaSure RF controller since
there are no field serviceable components within the unit.
WARNING: No modification of this equipment is allowed.
Periodic maintenance
The RF controller has been designed and tested to meet IEC
60601-1 and other safety standards. Maintenance is not required
as the system performs self-checks when power is turned on. To
clean the controller refer to the "Cleaning and Sanitizing" section.
RF power output test
The NovaSure RF controller Model 08-09 integrates automatic
power output testing into a power on self test (POST). During the
POST the controller's power output (Pc) is delivered into a shunt
resistor (Rs) located inside the controller. Pc is targeted to be 180
watts and Rs is nominally 25 ohms. During the POST, no power
is delivered to the disposable device connector at the front of the
controller.
NOTE: If a NovaSure disposable device is connected at
the time the controller is powered up, the POST will not be
performed and the controller will return to normal operation. If
a device is connected during the POST sequence, the POST will
terminate and the controller will return to normal operation.
The following procedure is used to execute the POST and display
the actual value of Pc and Rs determined:
1. With the switch on the power input module in the off position,
check to make sure a disposable device is not connected to the
RF controller.
2. Depress and hold the length UP and length DOWN arrows
simultaneously, then toggle the power switch at the power input
module while continuing to depress the arrows. This step initiates
the POST, which proceeds automatically.
3. Upon the completion of the POST (approximately 5 seconds), the
RF controller will generate one audible tone, and then display the
actual value of Pc for two seconds on the power set LED.
4. After two seconds elapse, the power set LED will change to display
the actual value of Rs for two seconds.
5. The power set LED will then change to 00, and the RF controller will
return to normal operation without further input from the user.
The acceptable limits on Pc = 180 W ± 10%. If Pc is not within
specification, a system fault will occur. The actual value of Rs is for
reference only.
