The generator is either not connected to facility
power or the power cord plugs are not seated
properly.
Make sure the generator is connected to a hospital-grade, facility
power receptacle with protective earth. Make sure the power cord
plugs are seated properly. See the
To Perform Initial Setup
section.
The inlet fuses are blown.
Replace the fuses with the same type and rating. See the
Specifications
section and the
To Replace the Fuses
section.
Electrical power is not present at the hospital-grade,
facility power receptacle.
Make sure electrical power is present at the hospital-grade, facility
power receptacle. If power is present and the generator still does not
power up, return the generator to Stryker for repair.
Unintended button activation is
experienced.
Screen is touched in two places simultaneously.
Touch the screen button in one place only.
Button does not activate when
touched or is activated when
not touched.
Touch screen requires calibration.
Perform touch screen calibration. See
To Change System Settings:
Display Settings
section.
Finger slid onto or off of button.
Touch the button directly. DO NOT slide onto or off of any button.
Light button touch.
Firmly touch the button.
Temperature reading appears
incorrect.
Components have not cooled down from sterilization.
After sterilization, allow components to cool to room temperature for at
least ten minutes before use.
Sporadic electrical interference
is experienced.
Electrical noise is present.
Turn off all electrical equipment not in use in the operating room.
Relocate electrical equipment or electrode to maximize the distance
between equipment; increase spatial distance.
Plug the generator and other operating room equipment into different
outlets (circuits).
The system impedance is too
high. The instrument may be
damaged.
The electrode/MultiGen cable connections is/are not
secure.
Ensure all connections are secure.
The electrode is not fully inserted into the cannula.
Ensure the electrode is fully inserted into the cannula.
The ground pad cable connection is not secure. The
ground pad placement is not secure.
Ensure the ground pad cable connection and/or the ground pad
placement is secure.
The cannula placement is not correct.
Ensure the cannula placement is correct and/or the ground pad
placement is secure.
The bipolar/monopolar mode is selected incorrectly.
Touch the PARALLEL button to select the correct mode of operation.
The electrode, MultiGen cable, or ground pad cable
is/are damaged.
Replace the electrode/MultiGen cable/ground pad cable.
If the error persists, contact Stryker customer service.
The system impedance is too
low. The instrument may be
damaged.
The electrode placement is not correct.
Ensure the electrode does not touch a metal implant or the ground
pad.
The electrode placement is operating in a parallel
mode.
Ensure the two electrode tips are not touching each other or a metal
implant.
If the error persists, contact Stryker customer service.
The temperature is not rising
at the expected rate. The
instrument may be damaged.
The electrode thermocouple is shorted.
If the temperature reading is below 36.6° C when the electrode is
inserted in the body and/or the temperature reading is not rising
when the power output is displayed as a positive value, replace the
electrode.
The electrode is not fully inserted into the cannula.
Ensure the electrode is fully inserted into the cannula.
The patient and/or electrode and cannula are moving
during the procedure.
Ensure the patient and/or electrode and cannula are not moving
during the procedure.
The electrode placement is not correct.
Ensure the active tip of the electrode is surrounded by tissue and the
tip is not in a blood vessel or bone.
The electrode or MultiGen cable is/are damaged.
Replace the electrode and/or MultiGen cable.
If the error persists, contact Stryker customer service.
