Group 1
The PressureTel
™
blood pressure monitors use RF energy only for their internal function. Therefore, its RF emissions are very
low and are not likely to cause any interference in nearby electronic equipment.

Class B
The PressureTel
™
blood pressure monitors are suitable for use in all establishments, including
domestic establishments and those directly connected to the public low-voltage power supply network that supplies
buildings used for domestic purposes.
Recommended safe distances between portable and mobile high-frequency telecommunication devices (e.g. mobile phones) and the PressureTel
™
blood pressure monitors
The PressureTel
™
blood pressure monitors are intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the PressureTel
™
blood pressure
monitor can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the PressureTel
™
blood pressure monitor,
according to the maximum output power of the communications equipment, as shown below.

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 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.
