SETTING UP:
When one sensor is used
1. First, insert the battery into the temperature sensor. (see "Install
and replace batteries in the temperature sensor").
2. Immediately after and within 30 seconds, insert the batteries into
Temperature Station (see "Install and replace batteries in the
Temperature Station"). Once the batteries are in place, all
segments of the LCD will light up briefly. Following the time as
12:00 and the indoor temperature 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 battery into the sensor, the Temperature
Station will start receiving data from the sensor. The outdoor
temperature and the signal reception icon should then be
displayed on the Temperature 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 there should
be a distance of no more than 330 feet (100 meters) between the
final position of the Temperature Station and the sensor (see
notes on "Mounting" and "915 MHz Reception").
When more than one sensor is to be used
1. User shall remove all the batteries from the Temperature Station
and sensors and wait 60 seconds if setting has been done with one
sensor before.
2. Insert the batteries to the first sensor.
3. Within 30 seconds of powering up the first sensor, insert the
