Frequently Asked Questions - BAR 686A OREGON SCIENTIFIC
How do I set up the weather station?
Insert 2 AA batteries into the main unit and 2 AA batteries into the remote sensor. The display will show indoor readings immediately. The outdoor sensor should be placed within 30m of the main unit. The atomic clock will automatically sync within a few minutes.
How do I change the batteries?
Open the battery compartment on the back of the main unit and replace with fresh 2x AA batteries. For the remote sensor, open the compartment and replace with 2x AA. After replacing, press the RESET button on each device with a pin if needed.
How do I synchronize the atomic clock?
The clock automatically attempts to synchronize with the DCF signal (Germany) or MSF (UK) every night. Ensure the unit is placed away from metal and electronic interference. If sync fails, you can manually search by pressing the RECEPTION button for 2 seconds.
What should I do if the outdoor temperature shows '--.-' or dashes?
This indicates no signal from the remote sensor. Check that batteries are fresh and properly inserted. Move the sensor closer to the main unit (within 30m). Press and hold the CHANNEL/SEARCH button on the main unit for 2 seconds to resync.
Can I add additional outdoor sensors?
Yes, the BAR686A supports up to 3 remote sensors. Additional sensors must be set to different channels (1,2,3) via a switch inside the battery compartment. Then press and hold the CHANNEL/SEARCH button to register them.
How do I set the alarm?
Press the ALARM button once to show alarm time. Press and hold ALARM for 2 seconds until the hour flashes. Use +/- to adjust hour, press ALARM again to set minutes. Press ALARM again to confirm. Toggle alarm on/off by pressing ALARM repeatedly.
Why is the weather forecast not accurate?
