Sharp Weather Station Model SPC344 The outside temperature doesn't register and I can't find my manual I replaced the batteries in the weather station and everything works fine except the outside temperature doesn't register on the outside piece or the inside weather station.

Your 'figure'??

Normally it has to be done in order. Remove both lots of batteries. Put the base unit batteries in first and then put in the outside unit batteries. they should pair. In fact the manual states that.

Instructions:
- Open the battery compartment on the weather station and insert 2 x AA
batteries, taking care to put them in the correct polarity. Close the battery
compartment.
- Open the battery compartment on the transmitter and insert 2 x AA batteries,
taking care to put them in the correct polarity. Close the battery
compartment.
Note: Ensure to install the batteries into the weather station and transmitter
within the same hour to ensure that they synchronize properly.

This says it is easy to set up, but there is a Fixya post that says there are a reset button in both units. In mine, I have to put a new battery in the main unit and then remove and replace the button in the remote unit.

My National Geographic Weather Station is the opposite. The outside sensor only indicates the temperature, but the single CR2023 battery lasts a year. The inside unit on my desk lasts around 5 - 6 months and lets me know if needs a battery by showing the outside temperature as ' -- '

Although the manual says 'rechargeable batteries are not recommended', I would try 4 Sanyo Eneloop batteries. Or you could contact Acurite Support and ask them if your battery use is excessive?

Make sure that all the batteries are good!!
This procedure outlines the typical process to pair the sensor and base.
Base Station Battery Installation
·Remove the printed vinyl label from the LCD screen of the base station
·Position the remote sensor near the base station
·Open the battery compartment at the back of the base station and insert (2) AA batteries according to the polarity markings. Replace the battery compartment cover.
·Within a short time the RF signal icon (located to the left of the outdoor temperature channel indicator) will start flashing. This indicates that the base station is ready to pick up the RF outdoor temperature signal from the remote sensor. It will continue to flash for 3 minutes or until the signal from the remote sensor is detected.

Register the Remote Sensor
·Open the battery compartment at the back of the remote sensor and slide the channel selector switch to your desired channel. For the first remote you may select any channel, for additional remotes select any unused channel
·Insert (2) AAA batteries according to the polarity markings. Be sure to install the batteries in the remote within the time that the RF signal icon is flashing on the base station. 1541 WeatherGuide Wireless Weather Forecaster with Barometer

In some of these weather stations, you have to install the batteries in the transmitter first and then the weather station within a certain time limit. Also, the weather station must be within a specified distance from the transmitter when replacing the batteries.

If you look on the weather station, there should be a make and model number. If you have that, you can visit the website (if there is one) and download an instruction booklet for your model.

I've had the same problem since I bought this unit 2+ years ago; when the outside temperature moves into the freezing zone, the sensor stops transmitting. I contacted Lacrosse-- all they could suggest was change the batteries. My solution: throw it in the trash!

Is the outside unit LED on? I replaced the battery on the outside unit and in doing this reset the outside information.

Sometimes the weather brings us surprises. For example, it is sunny in the morning bet when you leave your office, it is snowing outside. So, it can spoil our evening. In such cases, snow day finder is necessary because it can warn you about future weather changes.
