Receivers may be blocked by radio
signals occurring on or near their
operating frequencies, regardless of
the radio settings.
Radio transceiver equipment should
be tested regularly, at least weekly.
This is to determine, whether there
are sources of interference prevent-
ing communication, that the radio
paths have not been disrupted by
moving furniture or renovations, and
so generally protect against these
and other faults.
This equipment generates, uses and
can radiate radio frequency energy
and, if not installed and used in
accordance with the instructions, may
cause harmful interference to radio
and television reception. However,
there is no guarantee that interfer-
ence will not occur in a particular
installation. If this device does cause
such interference, which can be veri-
fied by turning the device on and off
(by removing the battery) the user is
encouraged to eliminate the interfer-
ence by one or more of the following
measures:
Re-orientate or re-locate the unit.
Increase the distance between the
smoke alarm and the device being
affected.
Consult the supplier or an experi-
enced radio/television technician.
