3. Safety Information

To ensure safe operation and prolong the life of your device, please observe the following safety guidelines:

• Do not expose the base unit to extreme temperatures, direct sunlight, or high humidity.
• The outdoor sensor is weather-resistant but should be placed in a sheltered location to protect it from direct rain and prolonged sun exposure for optimal performance and longevity.
• Use only the specified battery types and ensure correct polarity when inserting.
• Do not mix old and new batteries, or different types of batteries.
• Remove depleted batteries promptly to prevent leakage.
• Keep the device and batteries out of reach of children.
• Do not attempt to disassemble or repair the device yourself. Refer all servicing to qualified personnel.
• Clean the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.

4. Setup

4.1. Powering the Devices

1. Outdoor Sensor: Open the battery compartment on the back of the thermal hygrotransmitter. Insert 2 x 1.5 V AA batteries, observing the correct polarity (+/-). Close the compartment securely.
2. Base Unit:
   • Battery Operation: Open the battery compartment on the back of the base unit. Insert 3 x 1.5 V AAA batteries, observing the correct polarity (+/-). Close the compartment. In battery mode, the display backlight will activate briefly when a button is pressed.
   • Mains Power Operation: Connect the provided mains power adapter to the DC input port on the base unit and plug it into a power outlet. When powered by the adapter, the display backlight can be permanently activated and adjusted to two brightness levels. The display can also be switched off completely.

4.2. Sensor Placement

For accurate outdoor temperature and humidity readings, place the wireless outdoor sensor in a location that is:

• Out of direct sunlight.
• Protected from direct rain and snow.
• Well-ventilated.
• Within the maximum transmission range of 60 meters from the base unit. Avoid large metal objects or thick walls between the sensor and the base unit, as these can interfere with the signal.

4.3. Initial Synchronization and Radio-Controlled Clock

Once both the base unit and outdoor sensor are powered on, they will automatically attempt to synchronize. The outdoor temperature and humidity should appear on the base unit's display within a few minutes. The base unit will also automatically search for the DCF 77 radio signal to set the time and date. This process may take several minutes or hours depending on your location and signal strength.

If the radio-controlled clock does not set automatically, you may need to manually set the time or adjust the time zone. Refer to the operating instructions for manual time setting.

5. Operating Instructions

5.1. Display Overview

The colour display is divided into several sections, providing a clear overview of all relevant data:

• Outdoor Temperature & Humidity: Displays readings from the wireless outdoor sensor. Includes trend indicators.
• Indoor Temperature & Humidity: Displays readings from the base unit's internal sensors. Includes trend indicators.
• Time & Calendar: Shows the current time (radio-controlled), date, and day of the week.
• Weather Forecast: Animated weather symbols indicate the forecast for the next 12 hours based on air pressure changes.
• Dew Point: Indicates the dew point temperature.
• Temperature Alarms: Indicators for set temperature alarms (indoor/outdoor).

5.2. Weather Forecast

The weather station provides a local weather forecast for the next 12 hours based on changes in atmospheric pressure. The animated symbols (e.g., sunny, partly cloudy, cloudy, rainy, snowy) visually represent the predicted weather conditions. Note that this is a local forecast based on your immediate environment and may differ from regional forecasts.

5.3. Radio-Controlled Clock and Alarm

The integrated radio-controlled clock automatically synchronizes with the DCF 77 signal, ensuring highly accurate timekeeping. It displays the current time and date. You can manually adjust the time zone if needed. The clock also features an alarm function with a snooze option, making it suitable for use as an alarm clock.

• Setting Alarm: Use the "ALARM" button to enter alarm setting mode. Use the adjustment buttons to set the desired alarm time.
• Activating Snooze: When the alarm sounds, press the "SNOOZE" button to temporarily silence it. The alarm will sound again after a few minutes.

5.4. Temperature and Humidity Alarms

The weather station allows you to set high and low temperature alarms for both indoor and outdoor readings. When the temperature exceeds or falls below your set thresholds, an audible alarm will sound, and an indicator will flash on the display. Use the "ALERTS" button to configure these alarms.

6. Maintenance

• Cleaning: Wipe the display and casing with a soft, lint-free cloth. For stubborn marks, slightly dampen the cloth with water. Do not use abrasive cleaners, alcohol, or chemical solvents.
• Battery Replacement: Replace batteries in both the base unit and outdoor sensor when the low battery indicator appears on the display, or when performance degrades. Always replace all batteries in a device at the same time.
• Storage: If storing the device for an extended period, remove all batteries to prevent leakage. Store in a cool, dry place.
