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. A team of atomic physicists
is continually measuring every second, of every day, to an accuracy of ten billionths of a second
per day. These physicists have created an international standard, measuring a second as
9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. For more information on the
atomic clock and WWVB please see the NIST website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm.
QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the Wireless Weather Station and remote temperature sensor 3 to 5 feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then into the indoor
weather station.
(All remote temperature sensors must be started before the Wireless Weather Station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and remote temperature sensor will start to talk to each
other and the display will show both the indoor temperature and humidity, and an outdoor
temperature. If the Wireless Weather Station does not display both temperatures after the 15
minutes please retry the set up as stated above. After both indoor and outdoor temperatures are
displayed for 15 minutes you can place your remote temperature sensor outdoor and set your
time.
The remote temperature sensor should be placed in a dry, shaded area. The temperature
sensor has a range of 330 feet. Keep in mind that the 330 feet is in open air with no
obstructions and that radio waves DO NOT curve around objects. Actual transmission range will
vary depending on what is in the path of the signal. Each obstruction (roof, walls, floors,
ceilings, thick trees, etc.) will effectively cut signal range in half.
Example: A Wireless Weather Station with a 330 feet range is mounted on an interior wall, so
that the signal has to pass through one interior wall, one exterior wall, and across the 10 feet
width of the room between the 2 walls. The first wall will reduce the range to 165 feet, and the
second wall will reduce the range to 87 feet. Factoring in the 10 foot room, this leaves a
maximum of 77 feet of remaining signal range.
This allowance is typically enough for a frame wall with non-metallic siding; however certain
materials can reduce range even further. Metal siding, stucco, and some types of glass can
reduce signal range by as much as ¾ or more, compared to the ½ reduction typical of most
obstructions. It is possible to receive a signal through these materials, however maximum range
will be much less due to their tendency to absorb or reflect a much larger portion of the sensor’s
signal.
To complete the set up of your Wireless Weather Station after the 15 minutes have passed
please follow the steps that follow in the Detailed Set-Up Guide.

DETAILED SET-UP GUIDE
I. BATTERY INSTALLATION (When one temperature sensor is being used)
1. First, insert the batteries to the temperature sensor (see “A. Remote Temperature
Sensor” below).
2. Within 30 seconds of powering up the sensor, insert the batteries to the Weather
Station (see “B. Wireless Weather Station” below). Once the batteries are in place, all
segments of the LCD will light up briefly. Following the indoor temperature and
humidity, and the time as 12:00 will be displayed. If they are not shown in LCD after 60
seconds, remove the batteries and wait for at least 60 seconds before reinserting
them. Once the indoor data is displayed user may proceed to the next step.
3. After the batteries are inserted, the Weather Station will start receiving data signal
from the sensor. The outdoor temperature should then be displayed on the Weather
Station. If this does not happen after 2 minutes, the batteries will need to be removed
from both units and reset from step 1 and the signal reception icon is no longer shown.
A. REMOTE TEMPERATURE SENSOR
1. Remove the mounting bracket. The bracket snaps on
and off easily.
2. Remove the battery cover, by sliding the cover down.
3. Observing the correct polarity install 2 AA batteries. The
batteries will fit tightly (to avoid start-up problems make
sure they do not spring free).
4. Replace the battery cover by sliding upwards. Be sure
battery cover is on securely.
B. WIRELESS WEATHER STATION
1. Remove the battery cover. To do this, insert a solid object in the space provided
at the lower-central position of the battery cover, then push up and pull out on the
battery cover.
2. Observe the correct polarity, and install 2 AA batteries.
3. Replace the battery cover.
*When the signal is successfully received by the Weather Station, the icon will be
switched on. (If not successful, the icon will not be shown in LCD) So the user can
easily see whether the last reception was successful (icon on) or not (icon off). On the
other hand, the short blinking of the icon shows that a reception is being done now.

•If the signal reception is not successful on the first frequency (915MHz) for 45 seconds, the
frequency is changed to 920MHz and the learning is tried another 45 seconds. If still not
successful the reception is tried for 45 seconds on 910MHz. This will also be done for re-
synchronization.
PROGRAM MODE
Programming Note: If 30 seconds is allowed to pass, or the CH button is pressed
during the programming mode, the unit will confirm/set the last information entered—
the display will stop flashing and return to normal time-date readings. If you don’t leave
the program mode during the programming of sections III through XII, you can
advance to step 4 of the next program setting. If you do leave the program setting (or
want to program a specific setting) follow each instructional step to program that
setting.

VIII. TIME SETTING
There are two methods by which the time and date can be set:
A) Automatically via WWVB reception, or
B) Manually.
A. WWVB (Remote Control Time)
This method requires you to do nothing, except wait for the signal to be received, and to select a
time zone. Reception usually takes approximately 10 minutes during optimal conditions. The
best condition for reception is at night, between midnight and 6:00 am—when there is less
atmospheric interference. To keep your time as accurate as possible, Wireless Weather Station
conducts a WWVB search every night between these hours, and overrides any manually set
time. The WWVB tower icon (appearing in the TIME LCD) will flash when a signal-search is in
progress and a signal is being received, and will remain steady when the signal has been
received. If the WWVB time has not been received after 10 minutes of battery installation, you
may manually set the time or leave the time function alone (reception will occur regardless).
After a successful reception, no more reception attempt would be made until the following day.
B. MANUAL TIME SETTING
Note: When in the 12-hour format “P.M.” will appear to the left of the hour in the
time LCD between the hours of noon and midnight.
1. Press and hold the SET button for 5 seconds.
2. “LCD” will show in the time LCD and the number setting will flash.
3. Press and release the SET button five times.
4. The time will flash in the time LCD.
5. Press and release the IN button to advance the hours.
6. Press and release the OUT button to advance the minutes.
7. Press and release the SET button to confirm and advance to the year
setting.

sensitivity setting.
XII. SETTING THE FORECAST SENSITIVITY
Note: The forecast sensitivity can be adjusted to allow for areas that have a
higher or lower sensitivity to changing air pressure (for example coastal
areas have more pressure change than areas such as southern Arizona).
The numbers correspond to the amount of air pressure change necessary to
trigger a change in the forecast icon. Areas that tend to have more air
pressure change would set the sensitivity to 3, while areas that experience
lower than normal air pressure change would set the sensitivity to 1.
1. Press and hold the SET button for 5 seconds.
2. “LCD” will show in the time LCD and the number setting will flash.
3. Press and release the SET button ten times.
4. Either “1”, “2” or “3” will flash in the time LCD.
