11. Positioning of base station and transmitter
• Place the rain sensor horizontally in an area where rain can fall directly into the container, ideally
60 to 90 cm above the ground on a small platform. If necessary use the integrated water level.
• The base station can be placed onto any flat surface with the foldable leg or wall mounted at a
chosen location with the mounting hole, both found at the back of the unit. Make sure you avoid
the vicinity of any source of interference such as computer screens, TV sets or solid metal
objects.
• Once the desired location is chosen, check whether the transmission from the transmitter to the
base station is possible (transmission range of up to 100m in open areas). Within solid walls,
especially ones with metal parts, the transmission range can be reduced considerably.
• If necessary choose another position for the transmitter and/or base station.
• Mount the rain sensor base with 3 mounting screws.
12. Care and maintenance
• Clean the devices with a soft damp cloth. Do not use solvents or scouring agents.
• Check and clean the rain gauge periodically for optimum performance of the rainfall measure-
ment. The funnel should be routinely cleaned and freed from leaves and dirt.
• Remove the batteries if you do not use the devices for a long period of time.
12.1 Battery replacement
• Change the base station batteries when the battery symbol appears on time display.
• Change the batteries of the rain sensor, when the battery symbol appears on the rain amounts
display.
•
Please note:
When the batteries are changed, the contact between the transmitter and the base station must
be restored – so always insert new batteries into both devices or start the manual search for the
transmitter.
