Remote Temperature Sensor
Compatible Remote sensors

The TX191 remote sensor comes packaged with this atomic clock.

The TX191 (433MHz) remote sensor is compatible with this atomic clock.
Power Requirements

2-AA batteries power the remote sensor.

2-AA batteries power the clock.

We recommend Alkaline batteries for the remote sensor.

You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C.
Quick Connect
Explanation: Use the quick connect for an atomic clock and remote sensor that
have been working but lost connection due to interference or low batteries. This is
not the same as a thorough factory reset.
1. Bring the remote sensor and atomic clock together inside, and place the units
5-10 feet apart with nothing between them.
2. Hold the MINUS button for 5 seconds. The remote temperature area will flash.
3. Wait for 2 minutes for the remote temperature to appear on the atomic clock.

Factory Restart: If the above procedure does not work, please try the factory
reset.
Remote Temperature Signal Strength
Explanation: The atomic clock will search for the remote temperature remote
sensor for 3 minutes after batteries are installed or when the MINUS button is held
for 3 seconds.

The antenna symbol will flash during reception.

The temperature display will be dashes “---“.

If synchronization fails once, the antenna will lose one bar.

If synchronization fails twice, the antenna will lose two bars.

If RF (radio frequency) reception fails five times, the antenna symbol will show
without bars.

The antenna will show full display with successful RF (radio frequency)
reception.
Dashes show for Remote Temperature
Explanation: Dashes mean the connection is lost between the atomic clock and
the remote sensor.

Batteries often resolve the connection.

Distance/Resistance can cause loss of connection between the remote sensor
and the atomic clock.
