1. Innandyra sýningareining: Open the battery compartment cover on the back of the indoor display unit. Insert 2 x AAA rafhlöður (not included), ensuring correct polarity (+/-). Replace the cover.
2. Outdoor Rain Collector Sensor: Open the battery compartment cover on the outdoor sensor. Insert 2 x AA rafhlöður (not included), ensuring correct polarity (+/-). Replace the cover.

Note: It is recommended to use high-quality alkaline batteries for optimal performance and longevity.

2.2 Staðsetning utandyra skynjara

Proper placement of the outdoor sensor is crucial for accurate rainfall and temperature readings.

• Hæð: Place the outdoor sensor 1-2 metrar (3-6 fet) yfir jörðu.
• Stig yfirborð: Ensure the rain collector is installed on a completely level surface to guarantee accurate rainfall measurement. The self-emptying mechanism relies on a balanced tilt.
• Hreint svæði: Position the sensor in an open area, away from trees, buildings, or other obstructions that could block rain from entering the collector or interfere with wireless transmission.
• Sendingarsvið: The outdoor sensor should be within 60 metrar (200 fet) of the indoor display unit. Walls and other obstacles can reduce this range.
• Hitastig nákvæmni: For the most accurate outdoor temperature readings, place the sensor in a shaded, well-ventilated location. However, this may conflict with optimal rain collection. Consider prioritizing rain collection accuracy if temperature is less critical, or find a compromise location.

2.3 Upphafleg samstilling

After installing batteries in both units, they should automatically attempt to synchronize. Allow a few minutes for the indoor display to receive data from the outdoor sensor. If synchronization does not occur, try the following:

1. Bring the outdoor sensor closer to the indoor display unit.
2. Remove and reinsert batteries from both units to force a reset and re-synchronization attempt.
3. Gakktu úr skugga um að engar sterkar rafsegultruflanir séu í nágrenninu.

3.1 Skjáaðgerðir

Mynd 3.1: Ítarlegt view of the indoor display unit with labels for calendar, atomic time, rainfall digital display, indoor temperature, screen light/snooze button, week, rainfall graphical display, and outdoor temperature.

The LCD display provides various information:

• Tími og dagsetning: Automatically synchronized via WWVB radio signal.
• Hitastig innandyra: Current temperature measured by the indoor unit.
• Útihitastig: Current temperature measured by the outdoor sensor.
• Rainfall Digital Display: Shows current rainfall data.
• Rainfall Graphical Display (Historical Histogram): Visual representation of historical rainfall.
• Rafhlöðuvísar: Icons indicating low battery for both indoor and outdoor units.

3.2 ViewÚrkomugögn

The rain gauge offers 7 different rainfall measurement modes:

• Event Rainfall
• Hourly Úrkoma
• Dagleg úrkoma
• Weekly Rainfall
• Monthly Rainfall
• Yearly Rainfall
• Alger úrkoma

Ýttu á "RAIN/ALERT" button to cycle through these different rainfall data views. Historical rainfall values can be viewed manually on the display or via the bar graph.

The indoor display unit includes a dual alarm clock function with snooze mode (5-60 minutes or off) and three alarm repeat modes: Weekdays (Mon-Fri), Weekends (Sat-Sun), and Daily (Mon-Sun). Refer to the detailed instructions in the full manual for setting specific alarm times and modes.

3.5 Val á hitaeiningu

The display can show temperature in either Celsius (°C) or Fahrenheit (°F). A dedicated button (often labeled °C/°F or similar) or a setting within the MODE menu allows you to switch between these units.

4. Viðhald

4.1 Self-Emptying Mechanism

Mynd 4.1: Sprengd view of the outdoor rain gauge, highlighting the self-emptying tipping bucket mechanism and battery compartment.

The outdoor rain collector features a self-emptying tipping bucket design. This design significantly reduces the need for manual emptying. However, regular checks are recommended.

4.2 Cleaning the Rain Collector

Periodically inspect the rain collector funnel for leaves, debris, insects, or other obstructions that may clog the funnel and affect measurement accuracy. Gently clean the funnel and tipping bucket mechanism with a soft cloth and water if necessary. Avoid using abrasive cleaners or tools that could damage the sensor components.

4.3 Skipt um rafhlöðu

When the low battery indicator appears on the indoor display for either the indoor unit or the outdoor sensor, replace the batteries promptly to ensure continuous operation and accurate readings. Follow the battery installation steps in Section 2.1.

5. Bilanagreining

• Enginn skjár/rafmagn:
  Ensure batteries are correctly installed with proper polarity. Replace with fresh batteries if needed.
• No Outdoor Data (Rainfall/Temperature):
  Check if the outdoor sensor is within the 60-meter (200-foot) transmission range of the indoor unit. Reduce obstacles between the units. Remove and reinsert batteries in both units to re-establish connection.
• Ónákvæmar úrkomumælingar:
  Verify the outdoor sensor is installed on a perfectly level surface. Check the rain collector funnel for any debris (leaves, dirt, spiderwebs) that might be blocking the opening or interfering with the tipping bucket mechanism.
• Ónákvæmar hitamælingar:
  The outdoor sensor's temperature reading can be affected by direct sunlight. For more accurate ambient temperature, ensure the sensor is placed in a shaded, well-ventilated area, while still allowing for unobstructed rain collection.
• Screen Fading/Poor Contrast:
  The LCD screen may have an optimal viewing angle. Adjust your viewing position. Ensure batteries are not low, as this can affect display clarity.
• Difficulty Accessing Historical Data:
  Refer to the operating instructions (Section 3.2) for using the "RAIN/ALERT" and "UP HIST" / "DOWN MEM" buttons to navigate historical data. If issues persist, a full reset (removing batteries) might be necessary, though this will clear historical data.
• Alarm Sounds When Off:
  Double-check the alarm settings to ensure all alarms are deactivated if not desired. If the issue persists after checking settings, a unit reset may be required.
