Atomic Clock Factory Restart
Explanation: The factory restart returns the clock and outdoor sensor to an “out-of-the-box” default state
and often resolves an issue.
Factory Restart:
1.
Remove all power from outdoor sensor and clock.
2.
Press one of the buttons on the clock at least 20 times to clear all memory.
3.
Verify that the clock is blank before proceeding (there may be lines painted on the screen that will show
when there is no power).
4.
Leave both units without power for 15 minutes (very important).
5.
Insert fresh batteries into the outdoor sensor, then into the clock.
6.
Press the TX button on the outdoor sensor to transmit RF signal.
7.
Keep the outdoor sensor 5-10 feet from the clock.
8.
When sensor connection is established, the temperature will appear on the station. Allow the outdoor
sensor and clock to sit together for 15 minutes to establish a strong connection.
9.
Do not press buttons for 15 minutes.
•
For optimum 433MHz transmission, place the outdoor sensor no more than 330 feet (100 meters, open
air) from the clock.

Outdoor Sensor reads “NO”
•
If sensor loses connection to the clock for any reason, the clock will show NO in the outdoor
temperature area after 30 minutes.
•
The clock will search for 3 minutes every hour to reconnect with sensor.
•
Hold the SEARCH button 2 seconds to search for the outdoor sensor.
•
Icon will flash while searching for sensor. Outdoor sensor area will show dashes during the search.
When sensor is received the icon will be solid.
•
If no sensor received, icon will disappear after 3 minutes of searching if sensor is not found. NO will
again show in the outdoor sensor area.
Other steps to take:
•
often resolve the connection.
•
Distance/Resistance
can cause loss of connection between the Outdoor sensor and the atomic clock.
•
Turn the atomic clock 90 degrees towards the Outdoor sensor to provide better reception. This allows
more antenna surface to face the Outdoor sensor signal.

Inaccurate Outdoor Temperature Reading
Explanation: High Outdoor temperature readings are generally a location issue. Low Outdoor temperature
readings are power related or a sensor going bad.
•
The Outdoor sensor reads the environment where it is mounted. When mounted inside the home, it will
read inside temperature.
•
When the Outdoor sensor reads high during the day, but not at night, it is a
positioning
problem.
