Frequently Asked Questions - BAR 289 OREGON SCIENTIFIC

How to install the BAR 289 weather station?

Insert 2 AA batteries into the main unit and 2 AAA batteries into the outdoor sensor. Place the sensor outdoors sheltered from sun and rain. The main unit automatically searches for the radio signal for the clock.

How to synchronize the radio-controlled clock?

The clock automatically synchronizes every night. If the signal is weak, place the unit near a window and avoid interference. Synchronization may take up to 10 minutes.

What to do if the outdoor sensor does not connect?

Check that the sensor batteries are installed correctly. Reset the sensor by removing the batteries for 10 seconds. Press the 'RESET' button on the main unit. Ensure the distance between the unit and the sensor does not exceed 30 meters without obstacles.

How to interpret the weather icons?

The icons indicate a forecast based on atmospheric pressure: sunny for fair weather, partly cloudy for mixed conditions, cloudy for overcast, and rainy for precipitation. Accuracy is not 100% guaranteed.

How to change the station batteries?

Open the battery compartment on the back of the main unit. Replace the two AA batteries with new ones. For the outdoor sensor, open the compartment and replace the two AAA batteries. Use good quality alkaline batteries.

Why is the display blank or dim?

Check that the batteries are inserted correctly and are not discharged. Replace them if necessary. If the display remains blank, press the 'RESET' button with a paperclip.

Can I add a second outdoor sensor?

Yes, the station can support up to 3 outdoor sensors. You need to purchase a compatible sensor (model THN132N). To add it, remove the batteries from the main unit, insert batteries into the new sensor, then reinsert the main unit batteries. The sensor will be automatically recognized.

How to clean the weather station?

Use a soft dry cloth to wipe the screen and casing. Never use abrasive products or solvents. Avoid touching the screen with greasy fingers.

What to do in case of incorrect temperature display?

Check that the outdoor sensor is placed in the shade and away from heat sources (wall, ground). Make sure the batteries are good. If the problem persists, reset the sensor and the main unit.

Can the station work without an outdoor sensor?

Yes, the station will only display indoor data (temperature and humidity). Weather forecast and barometric trend will remain active, but outdoor data will be absent.

REMOTE SENSOR (RTHR328N)

This product is shipped with the RTHR328N Remote Sensor. The main unit can collect data from up to 5 sensors.

The THGR328N and THR228N sensors are also compatible with this weather station. (Additional sensors are sold separately. Contact your local stockist for more information.)

The RTHR328N sensor collects temperature readings and signals from official time-keeping organizations for the radio-controlled clock.

SENSOR SET UP

1. Open the battery compartment with a small Phillips screwdriver and insert the batteries matching the polarity (+ and -) as shown below.

2. Slide the EU / UK switch to the setting which best suits your location.
3. Press RESET.
4. Place the sensor near the main unit.
5. Press SEARCH to manually initiate signal sending between the sensor and the main unit. The reception icon on the main unit will blink for approximately 3 minutes while it is searching for the sensor. (Refer to the "Sensor Data Transmission" section for more information.)
6. Press the °C / °F button to select the setting you want.
7. Close the remote sensor battery compartment.
8. Secure the sensor in the desired location using the wall mount or table stand.

To fold out the stand:

For best results:

• Insert the batteries and select the unit, channel, and radio signal format before you mount the sensor.
• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 30 metres (100 feet) from the main (indoor) unit.
• Position the sensor so that it faces the main (indoor) unit, minimizing obstructions such as doors, walls, and furniture.
• Place the sensor in a location with a clear view to the sky, away from metallic or electronic objects.
• Position the sensor close to the main unit during cold winter months as below-freezing temperatures may affect battery performance and signal transmission.

NOTE The transmission range may vary and is subject to the receiving range of the main unit.

You may need to experiment with various locations to get the best results.

SENSOR DATA TRANSMISSION

Data is sent from the sensor(s) every 60 Seconds. The reception icon shown in the Outdoor Temperature Area indicates the status.

ICON DESCRIPTION
	Main unit is searching for sensors.
	At least 1 channel has been found.
	Sensor 1 is sending data. (The number shows which sensor is selected.)
--- shows in Temp Area	The selected sensor cannot be found. Search for the sensor or check batteries.

SELECT SENSOR CHANNEL

Press CHANNEL on the main unit, to switch between sensors 1-5.

The house icon shows the selected remote sensor.

To auto-scan between sensors, press and hold CHANNEL for 2 seconds. Each sensor's data will be displayed for 3 seconds.

To end auto-scan, press CHANNEL or MEMORY.

SEARCH FOR SENSOR

To search for a Thermo sensor, simultaneously press and hold CHANNEL and MEMORY for 2 seconds.

NOTE If the sensor is still not found, check the batteries.

CLOCK AND CALENDAR

This product tracks the time and date based on radio-controlled signals from the RTHR328N remote sensor, or manual settings that you enter.

RADIO-CONTROLLED CLOCK

The time and date are automatically updated by radio-controlled clock signals from official time-keeping organizations in Frankfurt (Germany) and Rugby (England) unless you disable this feature. The signals are collected by the remote sensor (RTHR328N) whenever it is within 1500 km (932 miles) of a signal.

Initial reception takes 2-10 minutes, and is initiated when you first set up the unit, and whenever you press RESET. Once complete, the reception icon will stop blinking.

The reception icon 📋 shown in the Clock Area indicates 2 factors:

- Connection between the main unit and the sensor that collects RF signals ( III )

- RF signal reception ( Ⓞ )

How these signals work together:

ICON MEANING
	The unit has contact with the remote sensor and has synchronized the time.
	The unit has contact with the remote sensor but the time has not been synchronized.
	The unit has lost contact with the remote sensor but the time is synchronized.
	The unit has lost contact with the remote sensor and the time is not synchronized.
	The unit cannot reach the remote sensor.

NOTE To force a manual search for the RF clock reception, press and hold SEARCH on the sensor (RTHR328N).

TURN RADIO-CONTROLLED CLOCK ON / OFF

If you wish to manually set the clock, you must first disable the radio-controlled feature. To do this, make sure you are not in Setting Mode, then press and hold DOWN on the main unit for 2 seconds. To enable it, hold UP for 2 seconds.

• When the RF clock is enabled this icon appear on the display.
