
See the section on mounting and distance/resistance/interference for details on
mounting the outdoor sensor.
Note: When your clock is powered on, it starts to receive WWVB signal for seven
minutes. The tower icon will flash.
Note: During reception of the WWVB time signal, the buttons will not function.
Outdoor Temperature Sensor
Compatible Outdoor sensors

The TW004 (433MHz) outdoor sensor comes packaged with this weather station.

This is the only compatible sensor.
Outdoor Temperature Signal Strength
Explanation: The weather station will search for the outdoor temperature outdoor
sensor for 3 minutes once batteries are installed or when the
▲
button is held for 3
seconds.

The temperature display will be dashes “---“.
Dashes show for Outdoor Temperature
Explanation: Dashes mean the connection is lost between the weather station and
the outdoor sensor.

Batteries often resolve the connection.

Distance/Resistance can cause loss of connection between the outdoor sensor
and the weather station.

Turn the weather station 90 degrees towards the outdoor sensor to provide
better reception. This allows more antenna surface to face the outdoor sensor
signal.

Try the factory restart.
Power Requirements

2-AAA batteries power the outdoor sensor.

We recommend Alkaline batteries for the outdoor sensor.

You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C.
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.

Look for heat sources such as sunlight, door or window frames or reflected heat.
