High Frequency (RF) Leakage Current

• Bipolar RF leakage current: <59.2 mA rms

• CEM output modes: < 150 mA rms at ð 50 W

REM Contact Quality Monitor

• Measurement Frequency: 80 kHz ± 10 kHz
• Measurement Current: <10 µA
• Acceptable Resistance Range
  • REM resistance measurements are ± 10% during RF activation and ± 5% when RF output is not activated.
  • REM patient return electrode: 5 to 135 ohms or up to a 40% increase in the initial measured contact resistance (whichever is less)
  • Patient return electrode without the REM safety feature (single section electrode): 0 to 20 ohms
  • If the measured resistance is outside the acceptable range(s) noted above, a REM fault condition occurs.

Internal Memory

• Nonvolatile, battery-backed RAM
  • Battery Type: 3v Lithium Button Cell
  • Battery Life: 5 Years
• Storage Capacity
  • One configuration, including three power settings and three mode settings.
  • The last twenty error codes detected by the generator.
  • The number of times and length of activation for each mode.
  • The average power setting used for each mode.
  • The total time the generator is on.
  • Other service-related information.

Serial Port

• RS-232 compatible; 9600 baud, 8 data bits, 1 stop bit, no parity
• The 9-pin connector supports the following signals
  • Pin 2 – isolated transmit (serial data output transmit line)
  • Pin 3 – isolated receive (serial data input receive line)
  • Pin 5 – isolated ground (reference for transmit and receive)

RF Activation Port

• The RF activation port is subminiature telephone jack attached to the contacts of a small relay. The contacts are closed when the output in energized and open at all other times. This port provides means to tell other equipment that RF current is being generated. This is useful when making EEG or ECG measurements.

Expansion Port

• The 15-pin connector supports the following signals
  • Pin 2 – isolated transmit (serial data output transmit line)
  • Pin 3 – isolated receive (serial data input receive line)
  • Pin 5 – isolated ground (reference for transmit and receive)
  • Pin 9 – RF disable: input signal which, when activated by an external device, disables active RF output
  • Pin 10 – RF current: output signal proportional to active RF current
  • Pin 11 – voltage: output signal proportional to active RF voltage

Operating Parameters

• Ambient Temperature Range: 50° to 104°F (10° to 40°C)
• Relative Humidity: 30% to 75%, non-condensing
• Atmospheric Pressure: 700 to 1060 millibars
• Warm-up time: If transported or stored at temperatures outside the operating temperature range, allow one hour for the generator to reach room temperature before use.

Transport and Storage

• Atmospheric Temperature range: -40° to 158°F (-40° to 70° C)
• Relative humidity: 10% to 100%, condensing
• Atmospheric Pressure: 500 to 1060 millibars
• Duration of Storage: If stored longer than one year, the battery must be replaced and a full checkout, including calibration, must be completed before use.
