Why is the outside temperature not displaying on the base?

New batteries required, and reset .

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.

To get the outside temperature working again, open the outdoor sensor box carefully loosening the one screw with a screwdriver, insert 3 brand new AA batteries, check phone for outside temperature. If not showing on the phone display, try changing the 'channel' setting, just above the batteries. Be careful not to break the tiny switch. Gently use a smaller flathead screwdriver, if needed. There are 3 settings. Mine worked fine on the first setting. If it is showing on the phone set screens, then, carefully screw the lid back on to the sensor box, and re-insert into the sensor wall holder. I keep mine in a plastic bag on a shelf outside, away from sun, so I can get a true reading day or night. It is always a bit warmer in the sunlight than the true outdoor air temperature. Enjoy

Batteries must come out of both the temperature sensor (transmitter) and base (clock and temperature display). Leave out for about 4 minutes. Replace the batteries in the temperature sensor FIRST and set it about 5 - 10 feet away from the base. Replace the batteries in the base and leave them both set without touching any buttons for at least 15 minutes (usually only takes 5 minutes or so). The temperature should start to display. You can set the clock manually to the correct time and have it get the updates via radio in the evening or night. Should work after all this just fine. (have done it alot of times this way over the years)

Good luck.

Also,

If you have lost the outside temperature on the clock display after replacing the transmitter battery then do the following:

1. Make sure you have good batteries installed in the remote transmitter
2. Remove the batteries from the main clock and keep them out until the clock display disappers.
3. Re-install the batteries in the clock.
4. Wait until the display returns and includes the outside temperature display as well.
5. Set the clock again for current time/date etc.
6. Bingo. You are in business.
