NOTE: Do not set the clock until the outdoor temperature is displayed.
Leave the transmitter next to the clock for 10 minutes.
Battery Replacement
Notes:
- Always wait at least 10 minutes after removing batteries before reinserting, to avoid
start up and transmission problems.
- To ensure your safety, be careful that the batteries do not spring free from the contacts
while changing them.
WWVB SIGNAL RECEPTION
Roughly 15 minutes after the batteries have been inserted, the WWVB time code
reception can automatically start. This reception typically takes 10 minutes in good
conditions. If the clock cannot detect the WWVB radio signal, it will continue to search
for the signal each hour between 12am and 6am. When the clock detects a WWVB radio
signal, the WWVB tower icon in the top center of the LCD clock display will start
flashing. When the time code is received, the WWVB tower becomes permanently lit and
the time will be displayed. If the tower icon flashes, but does not set the time or the
WWVB tower does not appear at all, then please take note of the following:
• Recommended distance to any interfering sources like computer monitors or TV sets is
a minimum of 6 feet (2 meters).
• Within concrete rooms (basements, superstructures), the signal is naturally weakened.
In extreme cases, place the unit close to a window facing towards Fort Collins, Colorado.
• During the night the atmospheric disturbances are usually less severe and reception is
possible in most cases. A single daily reception is adequate to keep the accuracy
deviation below 1 second.
You can also use the “SET” key to enter the setup mode to manually set the Time, Time
Zone and Date (see manual settings below).
When the clock has successfully connected with WWVB, it will override the manually
set time and date and update your clock to the current WWVB time. WWVB time
reception takes place from 12:00 am through 6:00 am each day (attempts WWVB
reception every full hour within this time frame). When the time signal is received for
example at 1:00 am, the radio-controlled clock will not attempt to receive the WWVB
signal for the remaining hours until 6:00 am. Therefore, the next signal attempt will take
place between 12:00 am and 6:00 am the next day. The other times WWVB reception
takes place, are upon setup and after manual time set exiting mode. Reception is
generally not possible during daylight hours due to the interference of the sun.
