88900 Atomic Clock does not read time and temperature.

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.

ANY time you repower your atomic clock base unit, any remote sensors must display data on your base unit display BEFORE you can touch or adjust any base unit display setting buttons or your sensors will never connect to your base unit!


There is a specific procedure that must be followed for linking sensors to your atomic clock:

Step 1. If you need to replace the remote sensor's batteries, do this FIRST. Disconnect any corded power to the sensor and replace sensor's batteries, Then reconnect any corded power supply.

Step 2. After completing Step 1, remove the batteries and/or power supply in the base display unit.

Step 3. After at least 30 seconds, reinstall batteries and/or power supply in base display unit. DO NOT TOUCH ANY SETTING BUTTONS ON THE BASE UNIT!

Step 4. Wait up to 1 hour for the remote sensor(s) and base display unit to synchronize and wirelessly connect. Once you see ALL your sensors display their data on the base unit display you can continue to Step 5.

Step 5. With sensor(s) synchronized (displaying data) to the base display unit, you can now continue to use the base unit display setting buttons to customize your clock to your personal display preferences.
