press and hold DOWN ( ) button for 2 seconds to begin a new signal
search. If the signal still isn t received, please make sure that:
· The remote sensor is in its proper location.
· The distance between main unit and remote sensor(s) is not over
100 feet (30meters).
· The path between units is clear of obstacles. Shorten the
distance if necessary.
· Fresh batteries are installed correctly in both remote sensor and
main unit.
If there is no reception, perform the following steps:
· Bring the main unit and r emote sensor close together.
· Remove four (4) small screws from the back of the remote sensor
with small Phillips screwdriver, and open the batter y
compartment.
· Remove the batteries from the battery compartment and reinstall
them in the same manner. Remote sensor LED indicator will flash
showing transmission of the signal.
· Remove the batteries from the main unit and r einstall them in the
same manner.
· Set the main unit CHANNEL to the same channel set on the
remote sensor. When the transmission is successfully received
the remote temperature will appear on the main unit s display.

TRANSMISSION COLLISION

Signals from the other household devices such as wireless doorbells,
home security systems, and entry control, may interfere with this product
or cause temporary reception interruption. This is normal and will not
13
affect the general performance of the product. The transmission and
reception of the temper ature readings will resume once the inter ference
subsides.

WWVB RADIO CONTROLLED TIME

The NIST (National Institute of Standards and Technology) radio station
(WWVB) is located in Ft. Collins, Colorado. It transmits an exact time
signal continuously throughout the most of the continental United States.
The Weather Forecaster receives the WWVB signal through the internal
antenna from up to 2,000 miles away. The radio controlled clock will
search for the atomic time signal. Due to signal strength reception can be
limited during the daylight hours.
The WWVB tower icon on the main 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 ar e not set automatically, please consider the
following:
· During night-time hours, atmospheric disturbances are reduced
and radio signal reception may improve. A single daily reception
is sufficient to keep the clock accuracy within 1 second.
· Make sure the unit is placed at 8 feet (2 meters) away from
interference sources: TV, computer monitor, microwave, etc.
· The received signal may be weakened within metal or concrete
wall rooms such as basements or office buildings. Place the
Projection Clock near the window for best reception.

ATOMIC CLOCK

Immediately after establishing communication betw een the main unit and
remote sensor, the atomic time signal receiver will open and start to
