2. Place the atomic wall clock onto the screw, using the hanging hole on the backside. Gently pull the atomic wall clock
down to lock the screw into place.
3. Choose a location 6 feet or more from electronics such as cordless phones, gaming systems, televisions,
microwaves, routers, etc.
4. Place within range of the outdoor transmitter.
5. The maximum transmitting range in open air is 200 feet (96 meters). Obstacles such as walls, windows,
stucco, concrete, and large metal objects can reduce the range.
6. For best WWVB reception, orientate the atomic wall clock with the front or the back facing Ft. Collins,
Colorado and mount on an exterior wall.
Position the Outdoor Transmitter
To achieve a true temperature reading, mount in a shaded location. While the outdoor temperature sensor is weather
resistant, avoid submersion in water or snow. We recommend that you mount the outdoor temperature sensor on an
outside North-facing wall. The transmission range is 200ft(open air). Obstacles such as walls, concrete, and large metal
objects can reduce the range. Place both units in desired location, and wait approximately 15 minutes before
permanently mounting to ensure that there is proper reception.
Wall Mount:
1. Remove the mounting bracket from the outdoor temperature sensor .
2. Place the mounting bracket in the desired shaded location (wall or table).
3. Through the screw holes of the bracket, mark the mounting surface with a pencil.
4. Screw mounting bracket onto the mounting surface. Ensure that the screws are flush with the
bracket. Do not over-tighten.
5. Insert the outdoor temperature sensor into the bracket.
Note: Mounting with adhesive tape is not recommended as a permanent mounting solution. Only use adhesive tape
during set-up process.
