Recommended Separation Distance Between Por table and Mobile HF
Communication Equipment and cardiowise Devices
The XRCISE STRESS ECHO MED is intended for use in electromagnetic environments with
controlled HF disturbances. To prevent electromagnetic interference make sure to maintain
the minimum distance between portable and mobile HF communication equipment and the
product according to the output power of the communications equipment as indicated
below.

For transmitters rated at a maximum nominal output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation of the applicable
column, where P is the maximum nominal output power of the transmitter in Watts as stated
by the transmitter manufacturer.
Please note:
⊗ At 80 MHz and 800 MHz, the higher frequency range applies.
⊗ These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.

Safety Instructions

For user safety the VDE (Verband der Elektrotechnik e.V.) has issued special instructions
for medical premises and electro-medical devices.
According to these instructions, devices with mains connection must be equipped not only
with a reliable insulation of live parts but also with an additional protective measure to
protect the user against the transfer of the supply voltage to touchable metal parts. For this
purpose, VDE subdivides so-called protection classes.
