4. Setup

4.1 Powering the Main Unit

1. Insert Batteries (Optional Backup): Open the battery compartment on the back of the main unit (refer to Image 3). Insert 4 AA batteries (not included), observing the correct polarity (+/-). These batteries serve as a backup in case of power outages.
2. Connect Power Adapter: Plug the included power adapter into the Power Supply Socket (DC 5V 1.2A) on the back of the main unit (refer to Image 3). Plug the other end into a standard wall outlet. The display will light up.

4.2 Installing the Wireless Outdoor Sensor

1. Insert Batteries: Open the battery compartment on the back of the outdoor sensor (refer to Image 2, C7). Insert 2 AA batteries (not included), observing the correct polarity (+/-).
2. Select Channel: On the outdoor sensor, use the "Channel 1 or 2 or 3" button (C6) to select a transmission channel (e.g., Channel 1). Ensure this channel matches the setting on the main unit during pairing.
3. Placement: Place the outdoor sensor in a shaded, dry location away from direct sunlight and rain to ensure accurate readings. Avoid placing it near large metal objects or electronic devices that could interfere with the wireless signal. The maximum transmission range is approximately 60 meters.

4.3 Pairing the Sensor with the Main Unit

1. Ensure both the main unit and the outdoor sensor have power.
2. The main unit will automatically search for the outdoor sensor. This may take a few minutes. The remote temperature and humidity readings (A1, A2) will appear on the display once connected.
3. If the sensor does not connect, press and hold the "MEM" button on the main unit for a few seconds to initiate a manual search. On the outdoor sensor, press the "TX" button (C5) to send a signal.

5. Operating Instructions

5.1 Time and Date Setting

Press the "TIME" button on the side of the main unit to enter time setting mode. Use the "UP" and "DOWN" buttons to adjust values, and press "TIME" again to confirm and move to the next setting (e.g., hour, minute, 12/24 hour format, year, month, day).

5.2 Alarm Clock and Snooze Function

Press the "ALARM" button to view or set the alarm time. Use the "UP" and "DOWN" buttons to adjust. To activate/deactivate the alarm, use the alarm on/off shift switch on the side of the unit (refer to Image 3). When the alarm sounds, touch the "Snooze / Backlight" area (refer to Image 3) to activate snooze for a few minutes.

5.3 Temperature Unit Selection (°C/°F)

On the main unit, press the "TEMP" button to switch between Celsius (°C) and Fahrenheit (°F) for temperature display. The outdoor sensor also has a dedicated "°C/°F" button (C4) to change its local display unit.

5.4 Display Brightness Adjustment

When powered by the AC adapter, the display offers four brightness levels. Use the "LIGHT" button on the side of the unit to cycle through these levels. When operating on batteries, the backlight will automatically turn off after 8 seconds to conserve power.

5.5 Weather Forecast

• Sunny
• Cloudy
• Overcast
• Rainy
• Heavy Rain
• Snow

6. Placement Guidelines

Optimal placement of both the main unit and the outdoor sensor is crucial for accurate readings and reliable wireless communication.

6.1 Main Unit Placement

• Place the main unit indoors, in a central location, away from direct sunlight, heat sources, or drafts that could affect indoor temperature readings.
• Ensure it is within the 60-meter wireless range of the outdoor sensor.
• The unit can be placed on a table or mounted on a wall using the hanging hole on the back (refer to Image 3).

6.2 Outdoor Sensor Placement

• Mount the outdoor sensor in a location that is protected from direct precipitation and direct sunlight. A shaded area under an eaves or porch is ideal.
• Ensure it is not near any heat-emitting appliances (e.g., air conditioning units, vents) or reflective surfaces that could skew temperature readings.
• Avoid placing it directly on the ground or near large metal structures that could block the wireless signal.

7. Maintenance

7.1 Battery Replacement

• Main Unit: If using batteries for backup, replace all 4 AA batteries when the low battery indicator appears on the display.
• Outdoor Sensor: Replace the 2 AA batteries in the outdoor sensor when its low battery indicator appears or if data transmission becomes unreliable.
• Always replace all batteries in a set with new ones of the same type.

7.2 Cleaning

• Wipe the main unit and outdoor sensor with a soft, damp cloth.
• Do not use abrasive cleaners or solvents, as these may damage the display or casing.

8. Troubleshooting

• No outdoor temperature/humidity reading:
    - Check if the outdoor sensor has fresh batteries and is powered on.
    - Ensure the outdoor sensor is within range (max 60 meters) and not obstructed by large metal objects.
    - Verify the channel selected on the outdoor sensor matches the main unit's setting.
    - Press the "TX" button on the outdoor sensor and initiate a manual search on the main unit (hold "MEM" button).
• Incorrect temperature/humidity readings:
    - Ensure both units are placed away from direct sunlight, heat sources, or extreme drafts.
    - For the outdoor sensor, ensure it is protected from rain and direct moisture.
• Display is dim or off:
    - Ensure the AC power adapter is securely connected and plugged into a working outlet.
    - If running on batteries, the backlight turns off after 8 seconds to save power. Touch the "Snooze / Backlight" area to temporarily illuminate.
    - Replace main unit batteries if using them for backup.
• Time/Date is incorrect:
    - Manually set the time and date as described in Section 5.1.
