7.1 Preventing electromagnetic interferences
The user can help avoid electromagnetic disturbances by keeping the
minimum distance
telecommunication devices (transmitters) and the BR-102 plus / BR-
102 plus PWA. The distance depends on the output performance of
the communication device as indicated below.
Portable HF telecommunication devices must not be used within

a radius of 0.3 m from the BR-102 plus / BR-102 plus PWA and its
cables.
Do not place the BR-102 plus / BR-102 plus PWA on top of other

electric/electronic devices - i.e. maintain a sufficient distance to
other devices (this includes the patient cables).
For permanent HF telecommunication devices (e.g. radio and TV), the
recommended distance can be calculated using the following formula:

. (The formula is based on the max. immunity level of 10 V/
d = 0.6 P
m in the frequency domain of 80 MHz to 3000 MHz).
d = recommended minimum distance in meters
P = transmitting power in Watts
For more information on operation in an electromagnetic environment
according to IEC/EN 60601-1-2, please consult the service manual.
