SETTING UP: 

Note: 

This weather station receives only 

one

 outdoor sensor.   

1. 

First, insert the batteries into the Temperature sensor. (see “

Install and replace batteries in 

the Temperature sensor

“). 

2. 

Immediately after and within 30 seconds, insert the batteries into Weather station (see “I

nstall 

and replace batteries in the Weather station

”). Once the batteries are in place, all segments 

of the LCD will light up briefly. Following the time as 12:00 and the "Weather girl" icon will be 
displayed. If these are not displayed after 60 seconds, remove the batteries and wait for at 
least 10 seconds before reinserting them. 

3. 

After inserting the batteries, the Weather station will start receiving data from the sensor. The 
outdoor temperature and the signal reception icon should then be displayed on the Weather 
station. If this does not happen after 3 minutes, the batteries will need to be removed from both 
units and reset from step 1. 

4. 

In order to ensure sufficient 915 MHz transmission however, this should under good conditions 
be a distance no more than 100 meters between the final position of the Weather Station and 
the sensor (see notes on “

Mounting

” and “

915 MHz Reception

”). 

 

Note: 

 

If the signal reception is not successful on the first frequency (915MHz) for 45 seconds, the 
frequency is changed to 920MHz and the learning is tried another 45 seconds. If still not 
successful the reception is tried for 45 seconds on 910MHz. This will also be done for re-
synchronization. 

BATTERY INSTALLATION 

INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION 

The Weather station uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please 
follow the steps below: 
 

1. 

Remove the cover at the back of the Weather station. 

2. 

Insert batteries observing the correct polarity (see marking). 

3. Replace 

compartment 

cover. 

 
 
 
 
 
 
 
 
 

 
INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE SENSOR 

The Temperature Sensor uses 2 x AA, IEC LR6, 1.5V battery. To install and 
replace the batteries, please follow the steps below: 
 
1. 

Remove the battery compartment cover at the back of the sensor. 

2. 

Insert the batteries, observing the correct polarity (see marking). 

3. 

Replace the battery compartment cover on the unit. 

 
 
 

 
Note: 

In the event of changing batteries in any of the units, all units need to be reset by following the setting 
up procedures. This is because a random security code is assigned by the sensor at start-up and this 
code must be received and stored by the Weather station in the first 3 minutes of power being supplied 
to it.
