Honeywell PCR11ELW - Manual (Page 4)

GETTING STARTED
* After batteries are installed, the WWVB time
signal receiver will automatically search for the
time signal. This will take about 5 – 8 minutes.
Always place clock by the window for better
reception.
* If the radio signal is received, the date and time will
be set automatically and the icon [ ] will appear.
* If after 8 minutes the time signal has not been
received, press the “ MODE ” button to set the
time manually. The clock will continue to search
for the WWVB time signal daily from 1:00am
to 4:30am. When the signal has been successfully
received, the time and date will be updated
automatically.

ATOMIC TIME AND WWVB SIGNAL
The NIST (National Institute of Standards and Technology) radio
station is located in Ft. Collins Colorado. It transmits an exact time
signal continuously throughout the continental United States at
60 KHz frequency. The Atomic Projection Clock with Temperature
can receive this WWVB signal through its internal antenna from up
to 2,000 miles away. Due to the nature of the Earth’s ionosphere,
reception can be limited during the daylight hours. The radio
controlled clock will search for an alternate station that derives its
signal from the NIST Atomic clock in Boulder, Colorado.
The WWVB tower icon on the main unit’s display will flash
indicating radio signal reception from the WWVB station. If the
tower icon is not fully lit, or if the time is not set automatically,
please consider the following:
* During night-time hours, atmospheric disturbances are typically less
severe and reception may be improved. A single daily reception is
sufficient enough to keep the clock accuracy reading within 1 second.
* Make sure the main unit is positioned at 8 feet minimum distance
from any interference source such as a TV, computer monitor,
microwave, etc.
* The successful reception of the atomic time signal depends on the
positioning and location of the clock. Always place the main unit
by the window for better reception.
* Within concrete wall rooms such as basements or office buildings,
the received signal may be weakened. Always place the unit
near the window.
