under the °C/°F button, push down on the TX button for 3 seconds to send a
wireless signal to the Weather Station.

 On the Weather Station, hold the CH button for 3-5 seconds to search for the

transmitter.

 For optimal 433 MHz signal reception, the outdoor transmitter should be placed

within 200 feet (60 meters) from the indoor Weather Station.

POSITIONING THE WIRELESS OUTDOOR TEMP./HUMIDITY TRANSMITTER

Once the Weather Station shows the outdoor temperature, place it and the
transmitter in the desired locations and wait approximately 1-hour before
permanently mounting the transmitter to ensure that there is proper reception. The
transmitter should be mounted vertically, in a shaded, protected area, at least 6 feet
from the ground to avoid damage and ensure accurate readings. The transmitter is
water resistant, not waterproof and should not be placed anywhere it will become
submerged in water or subject to standing water or snow.

WALL MOUNT

 Choose a shaded location (under an overhang) for the transmitter that

is within the confirmed wireless reception range of the Weather
Station for accuracy.

 Install one mounting screw (not included) into a wall leaving

approximately ½ of an inch (12.7mm) extended.

 Place the hanging hole (on the back of the transmitter) onto the

mounting screw and gently slide the transmitter down to secure it.

IMPORTANT: For true temperature and humidity readings, mount the transmitter
out of direct sunlight on a North-facing wall or in any other well shaded area like
under an eave or deck rail. The maximum transmitting range in open air is over 200­feet (60 meters). Obstacles such as walls, windows, stucco, concrete, and large
metal objects can reduce the range. Place the transmitter at least 6 feet in the air to
improve signal transmission.

WWVB RADIO CONTROLLED TIME

The National Institute of Standards and Technology (NIST) WWVB radio station is
located in Ft. Collins, Colorado. It transmits the exact WWVB time signal
continuously throughout the United States at 60 kHz. The signal can be received up
to 2,000 miles away through the internal antenna in the Weather Station. However,
due to the nature of the Earth’s Ionosphere, reception is very limited during daylight
hours. The Weather Station will search for a signal every night when reception is
best. The WWVB radio station derives its signal from the NIST Atomic Clock in
Boulder, Colorado.

THE WWVB RECEPTION ICON with full signal strength will appear on
screen if the reception of the WWVB atomic time is successful.

 The tower icon is solid: The Weather Station has received the WWVB signal.
 No tower icon shows: The Weather Station was unable to receive a signal.

Reposition the Weather Station for better signal reception or try again at bedtime.
 The Weather Station will start searching at UTC: 07:00. If there is no reception on

the first attempt, it will try again at 08:00, 09:00, 10:00 and 11:00 for at least 2 to

10 min.

 If the WWVB signal is strong it may establish reception in ABOUT 2-3 minutes.
 If the signal is marginal it will try to obtain a signal for up to 10 minutes.
 IMPORTANT: When operating on a/c power, to avoid interference, the backlight

and USB charge port will turn off while the Weather Station searches for the

WWVB signal. The backlight and USB charge port resume after a 2-10 minute

search which occurs during the late night or early morning hours.
Note: In case the Weather Station is not able to detect the WWVB-signal
(disturbances, transmitting distance, etc.); the time may be manually set.

BACKLIGHT:
A/C adapter: The backlight is on continuously when operating the Weather Station
with the 5-volt a/c adapter.

 HIGH: The backlight is defaulted to HI when the Adapter is in use.

and USB charge port will turn off while the Weather Station searches for the WWVB
signal. The backlight and USB charge port resume after a 2-10 minute search which
occurs during the late night or early morning hours.

WEATHER FORECAST ICONS:

The Weather Station predicts weather condition of the next 12-hours based on the
change of atmospheric pressure with 70-75% accuracy. Note: As weather
conditions cannot be 100% correctly forecasted we are not responsible for any loss
caused by an incorrect forecast.

The weather station samples the barometric pressure every twelve minutes. These
samples are averaged hourly and daily then stored in nonvolatile memory.
The three hour pressure icon change is based off of the last four average hourly
readings.

THIS STATION LEARNS!
Please allow 3-4 weeks for barometer calibration to generate an accurate
forecast.

IMPORTANT: As the weather station builds memory, it will compare the current

average pressure to the past forty day average pressure for increased accuracy.
The longer the station operates in one location the more accurate the forecast icons
will be.

Note: This is a power output (charging) port only. This port
will not supply power to the Weather Station.
 Connect your existing USB charging cord for your

external device to the USB charging port on the back of
the Weather Station to begin to charge. Charging times
will vary. Note: Check that your device will charge with

the USB cord it came with. Many USB cords are for
data transfer only, and cannot be used for charging.

 Output: 1A maximum current USB.
 Do NOT overload USB port.

MIN/MAX TEMPERATURE/HUMIDITY DATA: The Weather Station shows daily
minimum and maximum temperatures each day starting at midnight (12:00 AM).
The station automatically resets the min/max temperatures at midnight (12:00 AM).

 View MAX data: Press and release the MIN/MAX button once to view maximum

temperature and humidity values for indoor and outdoor data.

 View MIN data: Press and release the MIN/MAX button twice to view minimum
