Getting started

Insert the batteries

• Place the instruments on a table at a distance of about 1.5 meters from each other. Avoid being close to possible sources of interference such as electronic devices and radio equipment.

1. Rain sensor
   • Open the two tabs on each side of the rain sensor and lift off the funnel portion.
   • Open the battery compartment and insert two new AA 1,5 V batteries. Make sure the polarity is correct (see marking on the cover).
   • Close the battery compartment again.
   • Close the housing cover and lock it.
2. Base station
   • Remove the protective film from the base station display.
   • Open the battery compartment of the base station by pushing the battery compartment lid downwards with both thumbs. Insert two new AA 1,5 V batteries, polarity as illustrated. Make sure the polarity is correct. The device will alert you with a beep and all segments will be displayed for a short moment. Close the battery compartment again.

Outdoor values reception

• The base station will scan the outdoor values of the transmitter. The reception symbol of the rain sensor flashes. If the reception is successful, the rainfall amount (0.0 at the beginning) appear on the base station display. To simulate rainfall values move the rocker (transmission time 45 seconds).
• If the reception of the outdoor values fails, "- - -" appears on the base station display. Check the batteries and try it again. Check if there is any source of interference.
• You can also start the initialization manually. Press and hold the +/MODE button on the base station for three seconds. The base station will try to receive the measured values.

Operation

• If the key tone is enabled, each button operation is acknowledged with a beep.
• Press +/MODE button while in normal mode to switch between indoor temperature and date.
• Press and hold the +/MODE or – button in setting mode for fast mode.
• The device will automatically quit the setting mode if no button is pressed for 20 seconds.

Settings

• Press and hold the HISTORY button for 3 seconds. BEEP (default: on) flashes. Press the +/MODE or – button to deactivate or activate the key tone. Press the HISTORY button again and the setting sequence is shown as follows: hours and minutes, 24 or 12 hours display, year, month, day, month/day sequence Day/M or M/Day, the rain amount unit and the temperature unit: Adjust by pressing the +/MODE or – button.
• Confirm the setting with the HISTORY button.

1. 12/24-hour display setting
   • In setting mode you can choose between the 12 - or 24 hour system (default: 24 hours).
   • In the 12-HR system AM (before noon) or PM (after noon) appears on the display.
2. Date format setting
   • In setting mode the two different date displays can be selected: date/month (European version) or month/date (American version) (default: Day/M).
3. Rainfall amount unit setting
   • In setting mode you can choose between mm (millimeter) or in (inches) as rainfall amount unit.
4. Temperature unit setting
   • In setting mode, you can change between °C (Celsius) or °F (Fahrenheit) as temperature unit.

Rainfall amount indication

• The rainfall amount is shown on a corresponding cylinder graph.
• When it starts to rain the rain drop symbol begins to flash.
• NOW - rainfall amount at the start of the rain. Automatic resets after 30 minutes of no rainfall. The rain drop symbol stops flashing.
• Press the RAIN button in normal mode to change the display between the rainfall amount indications:
  • Rainfall amount of the last hour (ONE HR)
  • Rainfall amount of the last 24 hours (24HRS)
  • Rainfall amount of the last 7 days (7 DAYS)
  • Rainfall amount of the last month (MONTH)
  • Rainfall amount of the last year (YEAR)
  • Indication of TOTAL rainfall amount since setting up or the last reset.
• NOTE: Hold the – button for 3 seconds in the respective rainfall amount indication to clear the recorded readings. Every rainfall amount indication can be reset individually.
• The device will automatically quit the rainfall amount mode if no button is pressed for 20 seconds.

24 hours rain alert

• Press the RAIN button in normal mode for 3 seconds to enter the rain alert mode.
• ALERT OFF (default) appears on the display.

• The instrument stores the values of 12 month. Press HISTORY button again to scroll back the rain history for the last 12 months.
• The device will automatically quit the history mode if no button is pressed for 20 seconds.

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.

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 measurement. 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.

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.
