Weather Station 00771W not connecting to Outside Thermometer

After several years of faithful service, I recently noticed that the outside temperature was never changing on my 00771W weather station.  I figured that the battery was dead on the wireless thermometer so I went outside brought it in and replaced the batteries with non-expired energizer Alkaline batteries.  It turned on the LED flashes every 30 seconds.  Brought the thermometer inside.  But the Receiving unit did not pick up the thermometer.  It would look for about 5 minutes and then the wireless thing would stop fanning up and down and the -- would be left displayed.  Next, I reset the base unit by depressing a paper clip into the "Reset" port.  Same result.  So I confirmed that the thermometer and base were on the same channel.  Next I changed the selected channel.  Pulled the battery on both.  Put the battery in the thermometer first.  Watched.  Pulled the battery on both.  Put the battery in the base station first.  Watched.  Put new fresh alkaline batteries in the base station. Watched.  Pulled the battery on both, repeated first. 

I fear that the obvious answer is that the receiver in the base unit is dead, but I see in lots of forums that after following the basic instructions, someone says that they'll email instructions.  I'm also puzzled by why the inside thermometer and clock would still work well in the base unit, and figure that I may as well see what the emailed instructions say.

It might be the receiver, or it might be the transmitter in the outdoor sensor. When the sensor LED flashes, the logic chip inside has called for a transmission, but that doesn't ensure that a radio signal has been sent. If you know someone with the same system, or can find a way to "listen" to your sensor (maybe you know a ham radio enthusiast?), you might narrow it down. My bet is on the outdoor sensor, as outdoor service can be tough on electronics.

Hello John,

Please try the troubleshooting steps listed below. If this does not correct the issue, we would recommend replacing the sensor.  For your convenience, I have added a link below to the replacement. Thank you.


•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.

•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.

•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.

•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.

•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.

•Mixing different battery types (brands, old/new, etc.) is not recommended.

Hard reset:

- Bring both units side by side and remove all batteries, unplug display if it has an ac adapter

- Change the ABC Switch to a different setting and ensure that both are on the same setting. example - If on A, move both to C

- Place batteries into the outdoor sensor first

- Place batteries into display

- Allow units to sit side by side until they connect.
