It is a known issue

Try first a general reset:
- remove the batteries from the clock (thus turning it Off.)
- remove the batteries from the outside sensor (if you are not aware that it has batteries, then perhaps it is not working because the batteries are no good any more! check that also.)
- wait 10 minutes with no power to the device.
- put batteries back in, power On again.
- hit Reset.
- hit Receive button.
- change the channel for reception from the outside sensor.
- change the channel on the outside sensor to match that channel.
- then set the time once more, once the remote temperature is sensed once again.

If this does not get the outside temperature reading working again, you may have to replace that temperature sensor.

Search the manufacturers website and ebay. It may require a little time and effort.

Remove all batteries from outdoor sensor and weather station.

Press one of the buttons on the weather station at least 20 times to clear all memory.

Verify that the weather station is blank before proceeding (there may be lines painted on
the screen that will show when power is removed).

Leave both units without power for 15 minutes (very important).

Insert fresh batteries into the clock.

Insert fresh batteries into the outdoor sensor.

Press the TX button on the outdoor sensor to transmit RF signal.

Keep the outdoor sensor 5-10 feet from the forecast station.

When RF connection is established, the temperature will appear on the station. Allow the
outdoor sensor and weather station to sit together for 15 minutes to establish a strong
connection.

How do I set the day on my sharp spc798 dual alarm digital clock?

Hi Susuan,
One of these methods below should get your device working properly. Good luck!

The product information page
From the manual:
915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE SENSOR
The atomic clock will receive the temperature data within 3 minutes. If the temperature data is not being received 3 minutes after setting up (the display shows "- - -"), then please check the following points:
1. The distance of the atomic clock or outdoor temperature sensor should be at least 6 feet (2meters) away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 915MHz signal frequency can also cause interference.
Note:
When the 915 MHz signal is received correctly, do not re-open the battery cover of either the outdoor temperature sensor or atomic clock, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur.
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature sensor to the atomic clock (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up).

hello lucy... you most likely have some corrosion in the outdoor component. Remove the batteries from the outdoor component and clean the battery contacts with the eraser end of a common pencil. Reinstall the batteries and then give it up to 8 hours to start reporting accurately again. Joe

Thanks for choosing Fixya!

After replacing the transmitter batteries several times, I tried replacing the clock batteries. They must have been getting low. Once I put in new batteries in the clock it worked fine. Good Luck.

For the Sharp SPC374T Atomic Clock - Time Zone setting- Press the 'Time' button once, the time zone will show where 'Day' usually is, use the Up or Down buttong to adjust.

For the outdoor Thermo, credit to my neighbor for this one. Remove battery from main unit, wait 2-3 minutes. Reload batteries. Once you get a reading from the outdoor sensor, hit the reset on the main unit. You will have to reset the time zone as described above, but this worked for me after 10 months of no outside temp showing up!

Good luck,
Doc
