La Crosse Technology TX7U User Manual

The TX7U outdoor temperature/humidity sensor can be added to your existing 
units in operation. The outdoor temperature/humidity sensor measures the 
outdoor temperature and humidity (or any other location you wish to know the 
temperature and humidity) and transmits the data to the indoor display station.

I.   SETTING UP 
Before you begin, assign a number to each outdoor temperature/humidity sensor 
(i.e. #1 for outdoors, #2 for the basement, etc.) if you have multiple sensors. This 
will help you determine which temperature, from which outdoor 
temperature/humidity sensor, you are reading on the indoor display station. 
 
Note:  Remove batteries from all existing units in operation—including outdoor 
temperature/humidity sensor units and indoor display stations. When setting up 
multiple units it is important to insert batteries first into all the outdoor 
temperature/humidity sensors, and in numeric sequence. Second install batteries 
into the indoor display station. Transmission problems will arise if this is not done 
correctly and if the total time for setup exceeds 6 minutes.   
 

Follow these directions when first setting up, when replacing batteries, 
or for resetting purposes.

 
1. 

Remove the batteries from all existing display units in operation. 

2. 

Using a screwdriver, unscrew and open the battery cover located 
at the front of the outdoor temperature/humidity sensor.
