2. Within 30 seconds of powering up the transmitter, insert batteries into the Temperature
Station, observing the correct polarity (see marking inside battery compartment). Once the
batteries are in place, all segments of the LCD will light up briefly. Following the indoor

seconds, remove the batteries and wait for at least 60 seconds before reinserting them.
Once the indoor data is displayed you may proceed to the next step.
3. After the batteries are inserted, the Temperature Station will start receiving outdoor temp
data from the transmitter. The outdoor temperature should then be displayed on the
Temperature station. If this does not happen after 2 minutes, remove the batteries from
both units and start again from step 1.
4. In order to ensure sufficient 915 MHz transmission, the outdoor transmitter should be
placed a distance of no more than 200 feet (60 meters) from the Temperature Station and
