got an additional software filter that make them less sensible. So if machines minimum
distance is respected, no cross talking issues will be present. From the other side we need
such sensibility on Noise Detector, to face out all the possible issues (worst condition).
Find more detailed information, about machines required minimum distance, on all
Excite Service manuals.

Usually HR on TG machines can work even if machines are a little bit too near between
them, or even if a low level of electromagnetic noise is present around. Despite the Noise
Detector sometimes flashes a little bit. This is because the additional software filter on
cardio machines, just previously mentioned, and because when HR receiver succeed to link
to the nearest Chest Belt transmitter, it properly works ignoring the noises around, when far
and low.
•
Vario Excite, by having the HR receiver far from the user, because the kind of frame and
training, is more susceptible to electromagnetic noise and cross talking. In fact greater is the
distance between HR receiver and Chest Belt, more difficult is for the receiver to
succeed to link to the Chest Belt (because it can be engaged before by other HR signal or
noises). That's why in presence of low noises, when other machines could still succeed to
work, Vario could not. In this case it's enough to increase the distance of Vario from the
noise source or from the other machines.

POSSIBLE SOLUTIONS IN THE PRESENCE OF
ELECTROMAGNETIC FIELDS
The only effective solution in the presence of electromagnetic interference is to reduce the power
of the noise source, in 2 possible ways:
• Shielding the noise source.
• Increasing the distance between the noise source and the HR receiver, by changing the
position of the machines or moving the noise source far from them, if possible.

Open the back casing and replace the battery by a standard 9Volt ones.
