Range; Maintenance And Cleaning - Renkforce WH2315 Bedienungsanleitung

13. Range

The transmission range of the radio signals between outdoor sensor and basis station is up to 110 m under optimum
conditions.
However, the range values refer to the so-called "free field range". (Range in case of direct sight contact
between transmitter and receiver without any interferences).
In practical operation, however, there are walls, ceilings etc. between the transmitter and the receiver which
reduce the range correspondingly.
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.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings, plasterboard walls with metal stand construction
• Trees, stones
• Laminated/coated insulating glass panes
• Proximity to metal & conductive objects (e.g. heater)
• Proximity to the human body
• Other devices on the same frequency (e.g. radio headphones, radio speakers)
• Proximity to electrical motors/devices, transformers, mains adapters, computers, cables/lines

14. Maintenance and Cleaning

The product requires no servicing apart from replacing the battery/rechargeable battery. Servicing or repair must only
be carried out by a specialist or specialist workshop. There are no parts that require maintenance by you inside the
product. Therefore, never open it (except for the procedure described in these operating instructions for inserting or
replacing the batteries/rechargeable batteries/).
A dry, soft and clean cloth is sufficient for cleaning the product. Do not push the housing too strongly. This will lead
to scratches.
Dust can easily be removed with a long-hair, soft and clean brush and a vacuum cleaner.
The outdoor sensor can be wiped off with a rag moistened with clean water.
Regularly check if any, e.g., leaves have collected in the collection funnel of the rain sensor and remove them.
Clean the brightness and light sensor and the solar module regularly (every 3 months recommended).
Never use any aggressive cleaning agents, cleaning alcohol or other chemical solutions for cleaning, since
these may damage the casing (discolouration) or even impair function.
