Vercise™ DBS Physician Manual
The Vercise DBS System is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The users of the Vercise DBS System can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the Vercise DBS
System as recommended below, according to the maximum output power of the communications equipment.
Proximity Test
IEC 60601-1-2 Test Level
385 MHz: 27 V/m @ 18 Hz pulse modulation
450 MHz: 28 V/m @ FM modulation

5240 MHz, 5500 MHz, 5785 MHz: 9 V/m @ 217 Hz
pulse modulation
Note: For the frequency bands in this table, use the specified recommended separation distance. The recommended
minimum separation distance of 30 cm between portable and mobile RF communications equipment (transmitters)
and the Vercise DBS System apply to all other frequencies within the specified ranges.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
Essential Performance
Failure of the external electrical components will not result in an unacceptable risk to the
user.
Telemetry Information
The following parameters describe the wireless communication link between the
Stimulator and the Remote Control.
•
Frequency Band: 119 kHz to 131 kHz
•
Modulation type: FSK
•
Effective Radiated Power: 0.4 mW (‑4 dBm) maximum
•
Magnetic Field Strength (at 3 m distance): 94 μA/m
Wireless Security
The Vercise DBS System has a short range inductively coupled telemetry system.
A Remote Control has to be linked with a Stimulator to allow communication. The
Stimulator will not respond to any unlinked device. There are additional mechanisms that
ensure the integrity of the communicated data.
