Indications Relevant To The Range - Conrad Electronic CPA601 Bedienungsanleitung

14. Indications relevant to the range

The coverage of the transmission of the radio signals of the outdoor sensor to the radio
projection clock can reach up to 50m under optimum conditions. This is also often referred to
as the "outdoor range".

However, this ideal arrangement (e.g. projection clock and outdoor sensor on
a plain, even meadow without trees, houses etc.) never exists in practice.
Normally, the radio projection clock is set up within the house and the outdoor sensor is
positioned under a projected roof.
The range can sometimes be considerably reduced due to:
• walls, reinforced concrete ceilings
• coated/metallised insulated glass
• vehicles
• trees, brushes, earth, rocks
• the proximity to metallic & conductive objects (e.g. heating elements)
• proximity to human body
• Broadband interferences, e.g. in residential areas (DECT telephones, mobiles, radio-
controlled headphones, radio-controlled speakers, other radio-controlled weather stations,
babyphones etc.)
• Proximity to electric motors, transformers, power supply units, computers
• proximity to badly shielded or openly operated computers or other electric devices

Since local conditions vary from site to site, a definite range cannot be
guaranteed.
However, trouble-free operation is usually possible in a detached house.
If the projection clock does not receive any data from the outdoor sensor
(despite new batteries), reduce the distance between the projection clock and
the outdoor sensor, change the installation site or place the outdoor sensor in
a different location. Perform another outdoor sensor search (see chapter 11 i).
