Setup Guide
Battery install
Note: To avoid operating problems, please take note of battery polarity
when inserting alkaline batteries. Inserting batteries wrongly may lead to
permanent damage. For best results, avoid using rechargeable batteries.
- Gently remove remote sensor from mounting bracket
- Using a Phillips tip screwdriver, remove battery cover on back of
remote sensor
- Insert 2 AAA batteries, replace cover and tighten screw in place
- Remove battery cover on back of base station by depressing release tab
- Insert 3 AA batteries and replace battery cover until it clicks
- Wait 3 minutes or until outdoor temperature is displayed on base
station. Do not press any keys before outdoor sensor data received*.
* When Wireless Weather Station is powered on, the wireless
transmitter must synchronize with the base station to operate properly.
The duration of this synchronization – referred to as the “learning period” –
is approximated at 3 minutes. Pressing any key before the learning
process is complete will interrupt the process and require you to start
over by taking batteries out, waiting ten seconds, then reinserting them.
Please note that every time the remote sensor is powered up (for example,
after a change of batteries), it transmits a random security code to the
base station. Therefore, when changing batteries on transmitter, be sure
to restart the base station by powering off then back on, thus allowing for
the learning period to commence.
Wall Mounting
Base station:
The base station may be used in tabletop mode thanks to the built-in ip-
out kickstand. Hanging holes on the back of the unit allow for wall
mounting on any wall in the house. Before permanently mounting either
of the units, be sure to check that the radio signal can be received.
Please note that obstacles such as walls, concrete, and large metal
objects may reduce the range.
Remote Sensor:
To achieve a correct temperature reading, avoid mounting remote sensor
in direct sunlight. We recommend that you mount the remote sensor on
an outside North-facing wall. Use 3 screws to afx the wall bracket to the
desired wall, then push remote sensor into bracket until it clicks.

12) Pressure threshold setting (default 2hPa)
13) Storm threshold setting (default 4hPa)
- In the setting modes, press + key or MIN/MAX key change or scrolls
the value. Hold the +key or MIN/MAX key for 3 second will increase/
decrease digits in great steps.
- Press SNOOZE/LIGHT key or key idle 10 second, the setting mode will
return to Normal Mode
Note: Please set the units rstly before change units’ value. During
change of units setting, units’ value will change according to new units
but it might cause resolution loss due to its internal calculation algorithm.
Setting Calibrated Temperature
Temperature is measured by a resistive thermal device (RTD) and is
subject to electronic variation.
Temperature errors can also occur when a sensor is placed too close to
a heat source (such as a building structure, the ground or trees).
To calibrate the indoor or outdoor temperature, we recommend a
mercury or red spirit (uid) thermometer. Bi-metal (dial) and other digital
thermometers are not a good source and have their own margin of error.
Using a local weather station in your area is also a poor source due to

changes in location, timing (airport weather stations are only updated
once per hour) and possible calibration errors (many ofcial weather
stations are not properly installed and calibrated).
Place the sensor in a shaded, controlled environment next to the uid
thermometer, and allow the sensor to stabilize for 24 hours. Compare
this temperature to the uid thermometer and adjust the console to
match the uid thermometer.
To calibrate indoor or outdoor temperature, in the Set Mode with indoor
or outdoor temperature ashing, press the + key or MIN/MAX key to
increase or decrease the temperature setting (in increments of 0.1ºC or
0.18ºF) to match the calibrated or known temperature source.
Setting Calibrated Humidity
The display console allows you to calibrate both the indoor and outdoor
humidity. Humidity is a difcult parameter to measure accurately and
drifts over time. The calibration feature allows you to zero out this error.
To calibrate humidity, you will need an accurate source, such as a sling
psychrometer or Humidipaks One Step Calibration kit.
To calibrate indoor humidity, in the Set Mode with indoor humidity ashing,
press the + key or MIN/MAX key to increase or decrease the humidity
setting (in increments of 1%) to match the calibrated or known humidity
source. To return the indoor humidity to the measured value, press and
hold the SET key for 3 seconds and the humidity will return to the
uncalibrated value.
To calibrate outdoor humidity, in the Set Mode with outdoor humidity
ashing, press the + key or MIN/MAX key to increase or decrease the
humidity setting (in increments of 1%) to match the calibrated or known
humidity source. To return the outdoor humidity to the measured value,
press and hold the SET key for 3 seconds and the humidity will return to
the uncalibrated value.
Note: The remote (outdoor) thermo-hygrometer will always display the
measured humidity level and not the calibrated humidity level. Only the
console will show the calibrated value.
Note: The dew point calculation is based on the calibrated humidity level.
Setting Barometric Pressure
The display console displays two different pressures: absolute (measured)
and relative (corrected to sea-level).
To compare pressure conditions from one location to another,
meteorologists correct pressure to sea-level conditions. Because the air
pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be at if located at sea-level) is
generally higher than your measured pressure.

Thus, your absolute pressure may read 28.62 inHg (969 mb) at an
altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg
(1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the
average sea-level pressure around the world. Relative pressure
measurements greater than 29.92 inHg (1013 mb) are considered high
pressure and relative pressure measurements less than 29.92 inHg are
considered low pressure.
To determine the relative pressure for your location, locate an ofcial
reporting station near you (the internet is the best source for real time
barometer conditions, such as Weather.com or Wunderground.com),
and set your weather station to match the ofcial reporting station.
To change the relative pressure is ashing, press the + key or MIN/MAX
key to increase or decrease the relative pressure setting to match the
ofcial reporting station.

Weather Forecasting
These four weather icons represent the Wireless Weather Station’s
weather forecasting. There are also two weather tendency indicators to
show the air pressure tendency between the weather icons. Weather
forecasting is based upon the change in air pressure.
Weather Tendency Indicator
The weather tendency indicator arrows are located between the weather
icons to show the air pressure tendency and provide a forecast of the
weather to be expected by the decreasing or increasing air pressure. The
rightward arrow means that the air pressure is increasing and the
weather is expected to become better. The leftward arrow means that the
air pressure is decreasing and the weather is expected to become worse.
The change of weather forecast icon is in accord to the relationship
between current relative pressure and the pressure change since the last
six hours. If the weather is changing, the weather tendency indicator
(animated arrows) will be ashing for three hours indicating that a
weather change is happening. After that, if weather conditions have
become stable and no new weather change condition met, the arrows will
remain xed.
Changing Weather Examples
Storm Warning Indicator
The storm threshold can be set to suit the user’s preferences for storm
forecasting in the range of 3-9hPa. By default, Wireless Weather Station
is set to 4hPa. When there is a fall over the pressure threshold within 3
hours, the storm forecasting will be activated: the clouds with rain icon
and tendency arrows will ash for 3 hours indicating the storm warning
feature has been activated.
Note: Pressure Sensitivity Setting for Weather Forecasting
Areas that experience frequent changes in air pressure require a higher
setting compared to an area where air pressure is generally stagnant.
For example, if 4hPa is selected, then there must be a fall or rise in air
pressure of at least 4hPa before the weather station will register this as
a change in weather.
