Icon Atomic Time Reception Strength
Undefined data
No Reception for the past 24 hours
Weak signal, but can be decoded
Strong signal
The WWVB tower icon on the unit’s display will flash
indicating a radio signal reception from the WWVB station. If
the tower icon is not fully lit, or if the time and date are not
set automatically, please consider the following:
• During nighttime hours, atmospheric disturbances are
typically less severe and radio signal reception may improve. A
single daily reception is sufficient enough to keep the clock
accuracy within 1 second.
• Make sure the unit is positioned at 8 feet (2 meters) distance
from any interference source such as a TV, computer monitor,
microwave, etc.
• Within concrete wall rooms such as basements or office
buildings, the received signal may be weakened. Always place
the main unit near the window for better reception.
Once the atomic time signal is received, the date and time will
be set automatically, and the [ ] icon will appear.
• The atomic clock receiver is programmed that it will search for
the atomic time signal daily for 0:00, 3:00, 6:00, and 12:00 am.
• To enable or disable the atomic time receiver, press and hold
UP (? ) button for 3 seconds. If atomic time reception is
activated, a tower icon will start flashing. If reception is
disabled, the tower icon will disappear.
• If the time signal has not been received in 8 minutes, you may
set the time manually.
MANUAL SETTINGS
To select the time mode, press UP (? ) or DOWN (? ) until the
