QUICK SET-UP GUIDE
Hint: Use fresh good quality alkaline batteries.
1. Have the indoor weather station and remote temperature/humidity sensor 3 to 5 feet apart.
2. Batteries should be out of both the indoor weather station and remote temperature/humidity sensor units for
10 minutes.
3. Place the batteries into the remote temperature/humidity sensor first then into the indoor weather station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the indoor weather station and remote temperature/humidity sensor will start to talk to each other and the
display will show the indoor temperature/humidity and outdoor temperature/humidity. If the indoor weather station does
not display all information after the 15 minutes please retry the set up as stated above. After all information has been
displayed for 15 minutes you can place your sensor(s) outdoors and set your time.
Important Notes on Set-up and Operation
•The remote temperature/humidity sensor should be placed in a dry, shaded area.
•Fog and mist will not harm your remote temperature/humidity sensor but direct rain must be avoided.
•The remote temperature/humidity sensor has a range of 330 feet. Any walls that the signal will have to pass through
will reduce distance. An outdoor wall or window can have up to 30 feet of resistance and an interior wall can have up
to 20 feet of resistance. Your distance plus resistance should not exceed 330 ft. in a straight line.
•The remote temperature/humidity sensor transmits a signal every minute. After the batteries have been installed, the
indoor weather station will search for the signal for a duration of 5 minutes. If there is no temperature or humidity
reading in the OUTDOOR LCD after 5 minutes, make sure the units are within range of each other, or repeat the
battery installation procedure.
•If a button is pressed before the indoor weather station receives the signal from the remote temperature/humidity
sensor, you will need to follow the battery installation procedure again.
To complete the set up of your new wireless weather station after the 15 minutes have passed please follow the steps that
follow in the Manual Settings section.
WWVB RADIO-CONTROLLED (ATOMIC) TIME
The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio station is located
in Ft. Collins, Colorado, and transmits the exact time and date 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.

meters) away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the transmitters onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the 433MHz-signal frequency may
prevent correct signal transmission or reception. Neighbors using electrical devices operating on the 433MHz-signal
frequency can also cause interference.
Note: When the 433MHz signal is received correctly, do not re-open the battery cover of either the remote
temperature/humidity sensor or indoor weather station. The batteries may spring free from the contacts and force
a false reset. Should this happen accidentally reset all units (see “SETTING UP” above) or transmission
problems may occur.
The transmission range is around 330 feet (100 meters) from the remote temperature/humidity sensor to the indoor
weather station (in open space). However, this depends on the surrounding environment and interference levels. If no
reception is possible despite the observation of these factors, all system units have to be reset (see “SETTING UP”
above).

POSITIONING THE INDOOR WEATHER STATION:
The indoor weather station provides the option of table standing or wall mounting the unit. Before wall mounting, please
check that the outdoor temperature(s) can be received from the desired location(s).
To wall mount:
1. Fix a screw (not supplied) into the desired wall, leaving the head extended out by about ¼ inch
(5mm).
2. Place the indoor weather station onto the screw and pull down gently to lock into place.
3. Remember to ensure that the indoor weather station locks into place before releasing.
POSITIONING THE REMOTE TEMPERATURE/HUMIDITY SENSOR
The remote temperature/humidity sensor is supplied with a holder that may be attached to a wall with the screws supplied.
The remote temperature/humidity sensor can be mounted in three ways:
•Mounting with screws
•Mounting with adhesive tape
•Using the bracket as a stand
MOUNTING WITH SCREWS
1. Remove the mounting bracket from the remote
temperature/humidity sensor.
2. Place the mounting bracket over the desired location.
3. Through the screw holes of the bracket, mark the mounting
surface with a pencil.
4. Screw mounting bracket onto the mounting surface. Ensure
that the screws are flush with the bracket.
5. Insert the remote temperature/humidity sensor into the
bracket.
MOUNTING WITH ADHESIVE TAPE
1. With a nonabrasive solution, clean and dry the back of the mounting bracket and the mounting surface to ensure a
secure hold. The mounting surface should be smooth and flat.
2. Remove the protective strip from one side of the tape.
3. Adhere the tape to the designated area on the back of the mounting bracket.
4. Remove the protective strip from the other side of the tape.
5. Position the remote temperature/humidity sensor in the desired location, ensuring that the indoor weather station can
receive the signal.
MOUNTING USING THE STAND
The mounting bracket can be used as a stand by simply attaching the bracket to the bottom of the remote
temperature/humidity sensor. Once snapped in place the remote temperature/humidity sensor can then be placed on a
shelf, table or other surface where the temperature and humidity measurements are desired.

The mounting surface can affect the transmission range. For example, the unit is attached to a piece of metal; it may
either reduce or increase the transmitting range. For this reason, we recommend not placing the unit on any metal
surfaces or in any position where a large metal or highly polished surface is in the immediate proximity (garage doors,
double glazing etc.). Before securing in place, please ensure that the indoor weather station can receive the signal from
the remote temperature/humidity sensor at the positions that you wish to situate them.
CARE AND MAINTENANCE:
•Extreme temperatures, vibration and shock should be avoided as these may cause damage to the units and give
inaccurate forecasts and readings.
•When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scouring agents as they
may mark the LCD and casings.
•Do not submerge the units in water.
•Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the
recommended type.
•Do not make any repair attempts to the units. Return it to their original point of purchase for repair by a qualified
engineer. Opening and tampering with the units may invalidate their guarantee.
•Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes in forecasts and
readings and thereby reduce their accuracy.
