16. Information about range
Theproductworksinthe868MHzrangewhichisalsousedbyotherradioservices.Therefore,
restrictionsintheoperationandtherangecanoccurthroughthedeviceswhichworkonthesame
orneighbouringfrequency.
Therangestatedinthetechnicaldataisintheopen-spacerange,i.e.therangeatdirectvisible
contactbetweentransmitter(radioremotecontrol)andreceiver(doorlockactuator).
Inpracticaloperation,however,therearewalls,theceilingsofroomsetc.betweenthetransmitter
andthereceiverwhichreducetherangecorrespondingly.
The range can be reduced appreciably partly through
• walls,reinforcedconcreteceilings
• coated/steamedinsulationglasspanes
• vehicles
• trees,bushes,earth,rocks
• proximitytometallicobjects(e.g.metaldoors)
• proximitytothehumanbody
• broadbanddisturbances,e.g.inresidentialareas(DECTtelephone,mobiletelephones,radio
headphones,radioloudspeakers,babyphonesetc.)
• proximitytoelectricmotors,transformers,powerunits,computers
• proximitytopoorlyshieldedoropenlyoperatedcomputersorotherelectricaldevices
+
Asthelocalcircumstancesaredifferentateveryplaceofmounting,nocertainrange
canbeguaranteed.
