1. Open the battery compartment on the back of each wireless sensor.
2. Insert 2 AAA batteries into each sensor, observing the correct polarity (+/-).
3. Close the battery compartment securely.
4. Open the battery compartment on the back of the main weather station unit.
5. Insert 2 AAA batteries into the main unit, observing the correct polarity (+/-).
6. Close the battery compartment securely.

4.2 Sensor Pairing and Channel Assignment

It is recommended to set all sensors and their respective channels before powering on the main unit for the first time.

1. For each wireless sensor, locate the 'CH' button inside the battery compartment.
2. Press the 'CH' button to assign a unique channel (1, 2, or 3) to each sensor. The channel number will appear on the sensor's small display. Ensure each of your three sensors is assigned a different channel.
3. Once channels are assigned, power on the main unit. The main unit will automatically search for and connect to the sensors. This process may take up to three minutes for initial warm-up and data synchronization. During this time, initial readings may not be accurate.

4.3 Sensor Placement

Place the wireless sensors in desired locations to monitor temperature and humidity. Common placements include:

• Outdoor: Under an eave or in a protected area to shield from direct rain and sunlight.
• Indoor: In a kitchen, wine cellar, greenhouse, or other rooms where monitoring is desired.

Ensure sensors are within the effective transmission range of the main unit and away from large metal objects that could interfere with the signal.

• SET: Enters setup mode for time, date, and alarm settings.
• ALARM: Activates/deactivates the alarm and enters alarm setting mode.
• UP / MEM: Adjusts values upwards in setup mode; displays MAX/MIN records.
• DOWN / °C/°F: Adjusts values downwards in setup mode; switches temperature unit between Celsius and Fahrenheit.
• CH: Cycles through sensor channels (1, 2, 3) or displays all channels.
• SNZ / LIGHT: Activates snooze function when alarm sounds; turns on backlight.

5.3 Setting Time and Date

1. Press the SET button to enter time/date setting mode.
2. Use the UP / MEM and DOWN / °C/°F buttons to adjust the flashing value.
3. Press SET again to confirm and move to the next setting (e.g., hour, minute, year, month, day).
4. Repeat until all settings are configured.

5.4 Setting the Alarm

1. Press the ALARM button to enter alarm setting mode.
2. Use the UP / MEM and DOWN / °C/°F buttons to set the desired alarm time.
3. Press ALARM again to confirm.
4. To activate/deactivate the alarm, press the ALARM button outside of setting mode. An alarm icon will appear/disappear on the display.
5. When the alarm sounds, press the SNZ / LIGHT button to activate the snooze function for an additional 5 minutes.

5.5 Viewing MAX/MIN Records

Press the UP / MEM button to cycle through the maximum and minimum recorded temperature and humidity values for indoor and each outdoor channel. The display will show 'MAX' or 'MIN' indicators.

6. Maintenance

• Clean the device and sensors with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Avoid exposing the main unit to direct sunlight, extreme temperatures, or high humidity.
• Ensure outdoor sensors are protected from direct rain and snow to prolong their lifespan.
• Replace batteries when the low battery indicator appears on the display to ensure continuous operation and accurate readings.

7. Troubleshooting

• No display on main unit: Check battery polarity and ensure batteries are fresh.
• No outdoor sensor readings: Ensure sensors have fresh batteries and are assigned unique channels (1, 2, or 3). Verify sensors are within range of the main unit. Re-sync by removing and reinserting batteries in both the sensor and main unit.
• Inaccurate readings: Allow up to 3 minutes for sensors to warm up and stabilize after battery installation or power cycle. Ensure sensors are not exposed to direct heat sources or extreme cold beyond their operating range.
• Signal loss from outdoor sensor: This can occur if the sensor is placed too far from the main unit, or if there are significant obstructions (e.g., thick walls, large metal objects). Try relocating the sensor closer to the main unit or in a clearer line of sight. Extreme cold (below freezing) can also temporarily affect signal transmission.
