Battery Installation & Registration of Sensors
IMPORTANT: Install batteries to the home receiver FIRST and then the remote sensor.
For Home Receiver:
Remove the battery cover from the back of the unit. Insert (2) AA size batteries into the
battery compartment according to polarity indicated, close the battery cover. After installing
batteries to the home receiver, the outdoor channel (--) dash icon will flash for 2 minutes
indicating that the unit is waiting for remote sensor registration signal. The batteries must
be installed in the remote during this 2 minute interval. If the batteries have been placed into
the unit correctly, a beep will be heard.
For Wireless Remote Sensor:
During the 2 minutes that the home receiver is looking for home registration signal,
remove the battery cover using a coin or flat head screwdriver. Insert (1) 3V battery into
the compartment according to polarity indicated. Place the round rubber seal into the
compartment and replace the battery cover.
• If registration is successful, a beep confirmation tone can be heard. If not, check the
condition of the AA batteries, repeat the registration procedure again. Close the battery
door and back cover and tighten the screw on the sensor.
Note:
• The sensor will transmit the registration code automatically to complete the registration
after the batteries are inserted. If the batteries have already been inserted into the battery
compartment, use a pen to press & hold the yellow button for 2 seconds for registration.
• If (---) dash icon appears on the outdoor channel, move the sensor closer to the home
receiver. Repeat the registration procedure again.
Getting Started
Immediately after the installation of the batteries, the indoor temperature will show. The unit
starts to search for the outdoor temperature signal. The outdoor temperature will show in 3
minutes provided it is within the transmission range.
