SET UP
Note: This weather station receives only one outdoor transmitter.
IMPORTANT
Do not mix old and new batteries.
Do not mix alkaline, standard, or rechargeable batteries.
1. First, insert the batteries into the thermo-hygro transmitter and place 5-10 feet from the weather
station.
2. Within 30 seconds, insert batteries into weather station. Once the batteries are in place, all
segments of the LCD will light up briefly. Then the indoor temperature, humidity and comfort level
indicator will be displayed. If these are not displayed after 60 seconds, remove the batteries and
wait for at least 60 seconds before reinserting them.
3. After inserting the batteries, the weather station will start receiving data from the transmitter. The
outdoor temperature, humidity 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. Allow the weather station and transmitter to sit 5-10 feet apart for 15 minutes to establish a good
connection.
5. In order to ensure successful 915 MHz transmission after the initial set up, maintain an open air
distance, no more than 330 feet (100 meters) between the final position of the weather station and
the transmitter (see notes on “915 MHz Reception” and “Positioning”).

INSTALL AND REPLACE BATTERIES IN THE OUTDOOR TRANSMITTER
The thermo-hygro transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. When batteries need
to be replaced, the low battery icon will appear on the OUTDOOR section of the LCD.
To install and replace the batteries, please follow the steps below:
1. Remove the battery compartment cover at the back of the transmitter.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery compartment cover on the unit.
Note: When changing batteries in any of the units, all units need to be reset by following
the setting up procedures. This is because a security code is assigned by the transmitter at
start-up and this code must be received and stored by the weather station in the first 3
minutes of power supplied to it.
