INITIAL SET UP:
1. Insert 2 AA batteries (not included) into the Digital Atomic Clock (see Install Batteries in the Digital Atomic Clock).
The Digital Atomic Clock then shows time and indoor temperature.
2. Insert 2 fresh AA batteries into the transmitter, observing the correct polarity (see Install Batteries in the Outdoor
Transmitter).
Do Not Mix Old and New Batteries
Do Not Mix Alkaline, Standard, Lithium or Rechargeable Batteries
3. Keep the transmitter 5-10 feet from the Digital Atomic Clock for 15 minutes to establish a good connection.
4. Within 3 minutes the outdoor temperature should be displayed on the Digital Atomic Clock. If the outdoor temperature
is not displayed after 3 minutes remove batteries from the transmitter and the Digital Atomic Clock for 60 seconds and
start again from step 1.
5. For optimum 433 MHz transmission, the outdoor transmitter should be placed within 200 feet (60 meters, open air)
from the Digital Atomic Clock.
Note: The Digital Atomic Clock will start searching for the WWVB time signal for 2-10 minutes at start up.
WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously
throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna
in the Digital Atomic Wall Clock. However, due to the nature of the Earth's Ionosphere, reception is very limited during
daylight hours. The Digital Atomic Clock will search for a signal every night when reception is best. The WWVB radio
station derives its signal from the NIST Atomic Clock in Boulder, Colorado.
WWVB RECEPTION ICON with full signal strength will appear on screen if the reception of atomic time is
successful.
The tower icon will show solid when the Digital Atomic Clock has received the WWVB signal.
No tower icon displayed. The Digital Atomic Clock was unable to receive a signal at this time.
Reposition the Digital Atomic Clock for better signal reception or try again at bedtime.
The Digital Atomic Clock will start searching at UTC: 07:00 and if no reception on the first attempt it will try
again at 08:00, 09:00, 10:00, and 11:00. Each attempt will be at least 2 minutes and the most will be 10 minutes.
If there is no signal or too much interference the receiver will only be on for 2 minutes.
If the signal is good it may catch in ABOUT 2-3 minutes.
If the signal is marginal it will try to receive a signal for up to 10 minutes.
Manual Search: Hold the -/TIME button to start a manual signal search.
Note: In case the Digital Atomic Clock is not able to detect the WWVB signal (disturbances, transmitting distance, etc.);
the time can be manually set using the Program Menu.
