Range - Renkforce 1505092 Bedienungsanleitung

Whistling sound/feedback sound from the speaker of the screen/DVR
• The microphone of the radio camera is too close to the screen/DVR (e.g. during the function test). Maintain a larger
distance in the test.
• Reduce the volume at the screen/DVR.
IR remote control does not work
• Replace the battery in the IR remote control by a new one. Ensure correct polarity when inserting the battery.
• Point the front of the IR remote control at the receiver in the screen/DVR.
Recordings cannot be played back on the computer.
• Use a different software to play back the videos.

18. Range

The transmission range of the radio signals between radio camera and the screen/DVR is up to 200 m under optimum
conditions.
However, the range values refer to the so-called "free field range". However, this ideal arrangement (e.g.
screen/DVR and radio camera on a plain, even meadow without trees, houses, etc.) is never possible in
practice.
Usually, the screen/DVR is set up in the house and the radio camera is installed, e.g., at a carport or in a
stairwell.
Due to the different influences on radio transmission, no specific range can be guaranteed, unfortunately.
Usually, however, operation in a family home is possible without any problems.
If the screen/DVR does not receive any signal from the radio camera, reduce the distance between the
screen/DVR and the radio camera or align the aerials differently.
It is best when the aerials are in parallel to each other. The range reduces too far if the aerial tips point at
each other.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings
• Coated/metallised insulated glass, aluminium windows, etc.
• Trees, shrubbery, earth, rocks
• Proximity to metal & conductive objects (e.g. heaters, steel doors)
• Proximity to the human body
• Broadband interferences, e.g. in residential areas (router, WLAN devices, mobile phones, radio headphones, etc.)
• Proximity to electrical motors, transformers, mains adapters, screens
• Proximity to mains sockets, mains cables
• Proximity to badly shielded or openly operated computers or other electrical devices
