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 affect the general
performance of the product. The transmission and reception of the temperature
readings will resume once the interference 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 at 60 KHz
frequency. The Wireless In/Out Thermometer can receive this WWVB signal
through the 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 receives the
atomic time signal from the NIST Atomic clock in Boulder, Colorado.
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 night-time 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 Wireless
Thermometer near the window for better reception.

ATOMIC CLOCK
Immediately after establishing communication between the main unit and
remote sensor, the atomic time signal receiver will open and start to search for
the atomic time signal. The search usually takes between 5-8 minutes.
NOTE: Do not press any buttons on the main unit during auto search as it
may interrupt product’s operation, and you will need to start set up
procedure again.
Once the atomic time signal is received, the date and time will be set
automatically, and the [ ] icon will appear.
NOTE: It is necessary to set your Time Zone, having in mind that the
default zone is a US Pacific Standard Time (PST). (Refer to MANUAL
SETTINGS section)
If the time signal has not been received in 8 minutes, you may use the MODE
button to set the time and date manually. (Refer to the MANUAL SETTINGS
section).
After the clock is set manually, place the main unit by the window for the better
reception. The atomic clock receiver is programmed that it will continue to
search for the atomic time signal daily for every hour between 1:00 am and
4:30 am.
Once the time signal has been successfully received, the time and date will be
updated automatically.
TIME AND CALENDAR DISPLAY MODES
The Wireless In/Out Thermometer displays current time in two display modes –
in hour-minutes-seconds format and in hour-minutes-day.
The date is displayed in month-date format.
