r
The Wireless ECG Monitor is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Wireless ECG Monitor can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Wireless ECG Monitor as recommended below, according to
the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (w) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.

RF emissions CISPR 11 GROUP 1 The Vpatch System uses RF energy only for its
internal function. Therefore, its RF emissions are
very low and are not likely to cause any
interference in nearby electronic equipment.
RF emissions CISPR 11 Class B The Vpatch System is suitable for use in all
establishments other than domestic and those
directly connected to the public low-voltage
power supply network that supplies buildings
used for domestic purposes.
