Electromagnetic Compatibility (except M3813B and M3815B)

Note
These guidelines may not always apply. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and
people.
Philips Telemonitoring Set devices have a Radio Test button that sends
a reduced strength test radio signal to the Home Hub or TeleStation,
which sounds an audio tone if the test signal is successfully received.
This test can be used to determine whether sources of interference are
present. These sources can be turned off or moved away to reduce their
strength and reduce interference. In addition, Philips Telemonitoring
Set devices and Home Hub or TeleStation can be placed closer to each
other so that the radio transmission from the Philips Telemonitoring Set
devices to the Home Hub or TeleStation has less distance to travel and
interfering radio signals have less effect. The radio transmission from
the Philips Telemonitoring Set devices is repeated periodically so that
an intermittent source of interference should only delay reception.
Avoiding Static
Electrical
Discharges
Static discharges to Philips Telemonitoring Set devices may cause
temporary, unusual behavior. If a static discharge causes a temporary
malfunction, simply restart the measurement.
