Distance calculation for non-life-support equipment
Other equipment or devices can be a source of interference, or can be susceptible
to interference from a nearby noise source, such as TV broadcasts, speakers,
microwave ovens and other radio communication devices.
WARNING !
To avoid interferences between equipment and devices, we recommend
that the equipment be used at an adequate distance from such devices.
CAUTION
If it becomes necessary to use the equipment near other devices one must closely
observe its performance to check if the setup in which it is used, allows it to
perform at normal operational level.
CAUTION
•
When connections are made to the RS 232 port, one should be very careful
as to avoid touching the pins of the connectors themselves.
•
Before making any connections, we suggest using all ESD elementary
cautionary procedures: discharge the accumulated static electricity by
touching a conducting metal part connected to the ground protection of the
electrical system. As an alternative, touch a metallic part of a very wide
surface.
•
When making any connections double-check that both devices or equipment
to connect are turned off.
Recommended separation distances between portable and mobile RF communications equipment and
the
870 A / 870 S /870 C treadmills
The
treadmill model no. 860 A / 870 A is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the end user of the equipment can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment and the treadmill model no. 870 A / 870 S / 870 C as recommended below,
according to the maximum output power of the radio communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in
meters (m) can be determined 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.
NOTES:
• At 80 MHz and 800 MHz, the separation distance for 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.
