Carefully remove all components from the packaging. The package should include one indoor display unit and one outdoor rain collector sensor.

Image 2.1: Location of battery compartments for the indoor display (top right) and outdoor rain gauge (bottom right).
- ഇൻഡോർ ഡിസ്പ്ലേ യൂണിറ്റ്: Open the battery compartment cover on the back of the indoor display unit. Insert 2 x AAA ബാറ്ററികൾ (not included), ensuring correct polarity (+/-). Replace the cover.
- Outdoor Rain Collector Sensor: Open the battery compartment cover on the outdoor sensor. Insert 2 x AA ബാറ്ററികൾ (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 ഔട്ട്ഡോർ സെൻസർ പ്ലേസ്മെന്റ്
Proper placement of the outdoor sensor is crucial for accurate rainfall and temperature readings.

- ഉയരം: Place the outdoor sensor 1-2 മീറ്റർ (3-6 അടി) തറയുടെ മുകളിൽ.
- ലെവൽ ഉപരിതലം: 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.
- വിസ്തൃതമായ പ്രദേശം: 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.
- ട്രാൻസ്മിഷൻ ശ്രേണി: The outdoor sensor should be within 60 മീറ്റർ (200 അടി) of the indoor display unit. Walls and other obstacles can reduce this range.
- താപനില കൃത്യത: 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 പ്രാരംഭ സമന്വയം
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:
- Bring the outdoor sensor closer to the indoor display unit.
- Remove and reinsert batteries from both units to force a reset and re-synchronization attempt.
- ശക്തമായ വൈദ്യുതകാന്തിക ഇടപെടലുകളുടെ ഉറവിടങ്ങൾ സമീപത്തില്ലെന്ന് ഉറപ്പാക്കുക.

3.1 ഡിസ്പ്ലേ ഫംഗ്ഷനുകൾ

ചിത്രം 3.1: വിശദമായത് 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:
- സമയവും തീയതിയും: Automatically synchronized via WWVB radio signal.
- ഇൻഡോർ താപനില: Current temperature measured by the indoor unit.
- ഔട്ട്ഡോർ താപനില: Current temperature measured by the outdoor sensor.
- Rainfall Digital Display: Shows current rainfall data.
- Rainfall Graphical Display (Historical Histogram): Visual representation of historical rainfall.
- ബാറ്ററി സൂചകങ്ങൾ: Icons indicating low battery for both indoor and outdoor units.
3.2 Viewing Rainfall Data
The rain gauge offers 7 different rainfall measurement modes:
- Event Rainfall
- Hourly മഴ
- പ്രതിദിന മഴ
- Weekly Rainfall
- Monthly Rainfall
- Yearly Rainfall
- ആകെ മഴ
അമർത്തുക "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.

3.3 ബാക്ക്ലൈറ്റ് ഫംഗ്ഷൻ

Image 3.3: Comparison of the display in normal lighting and with the backlight activated for 15 seconds.
To activate the backlight, press the "വെളിച്ചം" or "SNOOZE/LIGHT" button (depending on model variation) located on the top of the digital rain gauge. The backlight will illuminate for approximately 15 seconds, allowing you to view the display in low-light conditions.
3.4 ഡ്യുവൽ അലാറം ക്ലോക്ക്

Image 3.4: The display unit showing alarm icons and examples of weekday/weekend alarm settings.
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 താപനില യൂണിറ്റ് തിരഞ്ഞെടുക്കൽ
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. പരിപാലനം
4.1 Self-Emptying Mechanism

ചിത്രം 4.1: എക്സ്പ്ലോഡഡ് 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 മഴവെള്ള സംഭരണി വൃത്തിയാക്കൽ
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 ബാറ്ററി മാറ്റിസ്ഥാപിക്കൽ
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. പ്രശ്നപരിഹാരം
- ഡിസ്പ്ലേ/പവർ ഇല്ല:
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. - Inaccurate Rainfall Readings:
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. - കൃത്യമല്ലാത്ത താപനില വായനകൾ:
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.
