Setup
1. Installing Batteries
- Open the battery compartment on the back of the main unit and each external sensor.
- Insert 2 x AA batteries (not included) into the main unit, observing polarity (+/-).
- Insert 2 x AA batteries (not included) into each external sensor, observing polarity (+/-).
- Close the battery compartments securely.

Figure 3: Battery Installation - The main unit and sensors require AA batteries.
2. Pairing Sensors
The main unit should automatically connect with the sensors once batteries are installed. If connection is not established:
- Ensure the main unit and sensors are within range (max 60m/200ft in open air).
- On each external sensor, select a unique channel (CH1, CH2, or CH3) using the "Channel Switch" inside the battery compartment (refer to Figure 2).
- On the main unit, press and hold the "CH" touch button for 3 seconds to initiate a search for sensors. The main unit will cycle through channels and display readings once connected.
3. Initial Settings (Time, Date, Temperature Unit)
- Set Time and Date: Press and hold the "SET" part of the "°C/°F SET" touch button for 3 seconds to enter time setting mode. Use the "MEM" and "CH" buttons to adjust values and "SET" to confirm and move to the next setting (Hour -> Minute -> Year -> Month -> Day).
- Select Temperature Unit: Briefly touch the "°C/°F" part of the "°C/°F SET" button to switch between Celsius (°C) and Fahrenheit (°F).
Operating Instructions
1. Display Overview
The main display provides a comprehensive view of environmental data:
- Indoor Temperature & Humidity: Current readings for the main unit's location.
- Outdoor Temperature & Humidity: Readings from the currently selected external sensor.
- Weather Forecast: Icons indicating predicted weather conditions (Sunny, Cloudy, Rainy, Sunset).
- Time & Date: Current time and date.
- Comfort Level: An icon indicating the indoor comfort level based on humidity (WET: 70-95%, COM: 40-70%, DRY: 20-40%).
- Low Battery Reminder: An icon appears when batteries in the main unit or a sensor are low.

Figure 4: Weather Forecast Icons - The display shows predicted weather conditions.
2. Channel Selection
To view data from different external sensors, briefly touch the "CH" button. The display will cycle through CH1, CH2, CH3, and then an automatic cycle mode (displaying each channel for a few seconds).

3. Alarm Clock and Snooze Function
The weather station includes an alarm clock with a default 5-minute snooze function.
- Setting the Alarm: Press and hold the "MEM" button to enter alarm setting mode. Use "MEM" and "CH" to adjust the alarm time and "SET" to confirm.
- Activating/Deactivating Alarm: Briefly press the "MEM" button to toggle the alarm on/off. An alarm icon will appear/disappear on the display.
- Snooze: When the alarm sounds, press the "Snooze/Light" button (usually located on top) to activate snooze. The alarm will sound again after 5 minutes.
- Stop Alarm: To stop the alarm completely, press any button other than "Snooze/Light", or press and hold "Snooze/Light" for more than 2 seconds.
4. Max/Min Temperature and Humidity Records
The weather station records the maximum and minimum temperature and humidity values for both indoor and outdoor environments.
- Briefly touch the "MEM" button to display the maximum recorded values (MAX).
- Touch the "MEM" button again to display the minimum recorded values (MIN).
- Touch the "MEM" button a third time to return to current readings.
- To clear the MAX/MIN records, press and hold the "MEM" button for 3 seconds while MAX or MIN values are displayed.

5. Backlight Operation
To illuminate the display in low light conditions, briefly press the "Snooze/Light" button (usually on top of the unit). The backlight will activate for 8 seconds and then turn off automatically to conserve battery power.

Maintenance
1. Battery Replacement
When the low battery indicator appears on the display, replace the batteries in the main unit or the corresponding sensor promptly to ensure continuous operation and accurate readings.
2. Cleaning
Wipe the main unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or immerse the devices in water.
3. Sensor Placement
For optimal performance, place external sensors in a shaded, dry location away from direct sunlight and rain. Ensure they are within the 60-meter (200-foot) wireless range of the main unit, minimizing obstacles like thick walls.
