After inserting batteries into both units, the base station will automatically begin searching for the outdoor sensor signal and the radio time signal.

2. Sensor Placement

Place the outdoor sensor in a shaded, dry location, protected from direct sunlight and rain, to ensure accurate temperature and humidity readings.
Ensure the sensor is within the maximum transmission range of 60 meters (197 feet) from the base station. Walls and other obstacles can reduce this range.
Avoid placing the sensor near large metal objects or electrical appliances that could interfere with the wireless signal.

3. Initial Synchronization

Once both units are powered, the base station will attempt to connect to the outdoor sensor and receive the radio-controlled time signal. This process may take a few minutes. If the outdoor temperature/humidity or time does not appear after 10 minutes, refer to the Troubleshooting section.

Operating Instructions

Display Overview

The display is divided into several sections, providing a clear overview of weather data and time information.

FORECAST: Displays weather icons indicating the predicted weather for the next 12-24 hours.
OUTDOOR: Shows the current outdoor temperature and humidity received from the wireless sensor. Includes daily high (HI) and low (LO) values.

Setting Time and Date

The weather station automatically sets the time and date via a radio signal (DCF77). If the signal is not received or you are outside the reception area, you can set the time manually.

Automatic Synchronization: The radio signal icon will flash during synchronization and remain solid once successful.
Manual Setting: Refer to the specific buttons on your device (usually labeled MODE, SET, or similar) and follow the sequence to adjust hours, minutes, year, month, and day. Consult the quick start guide included in the package for exact button functions.

Alarm Function

The weather station includes an alarm with a snooze function.

Setting the Alarm: Press the ALARM button (or similar) to enter alarm setting mode. Use the UP/DOWN buttons to adjust the alarm time.
Activating/Deactivating Alarm: Press the ALARM button again to toggle the alarm on or off. An alarm icon will appear on the display when active.
Snooze Function: When the alarm sounds, press any button (except the alarm off button) to activate snooze. The alarm will sound again after a few minutes.

Max/Min Values

The device records maximum and minimum temperature and humidity values for both indoor and outdoor measurements.

Viewing Max/Min: Press the MAX/MIN button (or similar) repeatedly to cycle through current, maximum, and minimum values.
Resetting Max/Min: Daily max/min values reset automatically. An additional memory allows for manual reset of selected values by pressing and holding the MAX/MIN button for 3 seconds.

Comfort Zone Indicator

The indoor section of the display includes a comfort zone indicator, which visually represents the quality of the indoor air based on temperature and humidity levels. This helps you maintain an optimal indoor climate.

Maintenance

Battery Replacement: Replace batteries in both the base station and outdoor sensor when the low battery indicator appears on the display. Always replace all batteries in a unit at the same time with new ones of the same type.
Cleaning: Clean the device and sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no water enters the battery compartments or electronic components.
Storage: If storing the device for an extended period, remove all batteries to prevent leakage.

Troubleshooting

Problem	Possible Cause	Solution
No outdoor temperature/humidity reading.	Outdoor sensor out of range. Interference from other devices. Low batteries in outdoor sensor. Synchronization failure.	Move sensor closer to the base station. Relocate sensor away from electronic devices. Replace batteries in the outdoor sensor. Remove batteries from both units, wait 1 minute, then reinsert batteries into the sensor first, then the base station.
Incorrect time or no radio signal icon.	Weak radio signal. Interference. Manual time setting required.	Move the base station to a window or an area with better reception. Avoid placing near electronic devices. Set the time manually if automatic synchronization fails consistently.
Display is dim or blank.	Low batteries in base station. Incorrect battery installation.	Replace batteries in the base station. Check battery polarity.
