433MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER 

The atomic clock will receive the temperature data within 4 minutes. If the temperature data has 
not been received 4 minutes after setting up (the display shows “- - -”), then please check the 
following points: 
1. 

The distance of the atomic clock or outdoor temperature transmitter should be at least 6 feet 
(2 meters) 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 (433MHz)  may prevent correct signal transmission and reception. 

4. 

Neighbors using electrical devices operating on the 433MHz signal frequency can also 
cause interference. 

 

Note:

 

 

When the 433 MHz signal is received correctly, do not re-open the battery cover of either the 
outdoor temperature transmitter 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 
transmitter 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

). 

 

CHANGING THE DISPLAY MODE 

(SECONDS,TEMPERATURES AND HUMIDITY)

 

There are four possible display modes to view the seconds, temperatures and humidity.  

 

The 

indoor humidity, indoor temperature and outdoor temperature display is the default (factory) 

setting. 

 
 
 
To change the display:

 

1.  Press and release the + key.  The display should now show the 

seconds, indoor temperature 

and outdoor temperature.
