BATTERY & ADAPTER INSTALLATION
Home Receiver Unit:
Main Power Source: Plug in the 6.0V adapter into the adapter socket at the back for basic operation
and continuous backlight.
Backup Power: Lift off the battery cover, install 3 pieces of AA backup batteries according to the
polarity indicated, close the battery cover.
Remote Sensor:
Loosen the screws on the battery door with a small screwdriver, insert 2 pieces of AAA batteries
according to the polarity indicated. Replace the cover and tighten the screws.
ALTITUDE SETTING
After battery installation, the main unit will enter altitude setting mode directly. Press “ ” or “ ” to
select the unit in meter or feet. Press “PRESSURE” to confirm. Then press “ ” or “ ” to enter your
current altitude. Press “PRESSURE” to confirm and exit the setting. This allows the unit to provide a
more accurate weather forecast reading. (For more information, see “WEATHER FORECAST &
BAROMETRIC PRESSURE” section)
SETTING UP THE WIRELESS THERMO-HYGROMETER:
For the first installation, always turn on the home unit and then the remote sensor. Set Channel 1
Set channel 2 and channel 3 for the 2nd and 3rd sensor.
for the first remote sensor.
Press and hold CHANNEL/SEARCH button on main unit until a beep is sound to search for
remote sensor.
Press the Tx button on the back of remote sensor to transmit RF signal.
When RF connection is established, the respective temperature & humidity of the selected
channel will appear on the main unit.
RADIO-CONTROLLED CLOCK
The unit will start synchronizing the clock after battery/adapter installation or reset. In normal mode,
press “
“ in the battery compartment to enforce searching of radio-controlled clock signal. The
antenna icon will appear during synchronization, if the icon disappear afterwards, radio time signal is
not available at the moment.
Try other locations later.
Place the unit away from source of
interference such as mobile phones, appliances, TV etc.
Antenna icon with full signal strength
will appear on screen if the reception of radio-controlled
time is successful. The radio-controlled clock will have a daily synchronization at 02:03 and 03:03
everyday. Each reception cycle is minimum 2.5 minutes and maximum 10 minutes.
WEATHER FORECAST & BAROMETRIC PRESSURE
The unit predicts weather condition of the next 12 – 24 hours based on the change of atmospheric
pressure.
The coverage area is around 30 – 50 km. The weather forecast is based on atmospheric
pressure change and is about 70-75% correct. As weather conditions cannot be 100% correctly
forecasted, we cannot be responsible for any loss caused by an incorrect forecast.
SUNNY
PARTLY CLOUDY
CLOUDY
RAINY
STORMY
To obtain an accurate weather forecast & barometric pressure reading, you need to input your current
altitude. After the reset of the unit, it will enter the altitude setting mode. Press “ ” or “ ” to set the
unit first, and then press “PRESSURE” and enter your current altitude. Press “PRESSURE” to confirm
and exit the setting. You can also hold “PRESSURE” button to enter altitude setting mode during
normal use.
Press PRESSURE button to select pressure unit between hPa, inHg & mb.
IN/OUT TEMPERATURE & HUMIDITY
Temperature reading is located on the lower left of the display and humidity is on the lower right.
Press “C/F“ button to select temperature unit C/ F.
Press CHANNEL/SEARCH button to select indoor, Ch1, Ch2, Ch3 and auto-channel scrolling
display modes.
IN/OUT HEAT INDEX
Heat Index combines the effects of heat and humidity. It is the apparent temperature of how hot the
heat-humidity combination makes it feels.
Press “Heat Index/Dew Point” button once to show the respective indoor or outdoor heat index on the
lower left display. “HEAT INDEX” icon will appear.
IN/OUT HEAT INDEX ALERT INDICATOR
Heat index alert indicators of the respective indoor or outdoor channels
Caution
Exercise more fatiguing than usual
Extreme caution
Heat cramps, exhaustion possible
Danger
Heat exhaustion likely
Extreme danger
Heat stroke imminent
IN/OUT DEW POINT
Dew point is the saturation point of the air, or the temperature to which the air has to be cooled in
order to get condensation.
In normal mode, press HEAT INDEX / DEW POINT button twice to show the respective indoor or
outdoor dew point reading on the lower left display. “DEW POINT” icon will appear.
IN/OUT COMFORT LEVEL
In/Out Comfort indicator combines the effect of temperature & humidity and displays in 3 levels:
COMF:
Comfortable level, ideal range for both temperature & humidity
WET:
Contain excess moisture
DRY:
Contain inadequate moisture
COLOR BAR GRAPHS
The color graphs are designed as an intuitive way to gauge the weather at a glance.
The left color bar graph represents the respective In/Out temperature, heat index or dew point of the
current display mode. The right graph represents the respective In/Out humidity. As the
measurements change, the number of illuminated bars changes automatically.
MAXIMUM / MINIMUM MEMORY
Press MEMORY button repeatedly to view the maximum & minimum values of temperature, humidity,
heat index or dew point readings. To clear the memory record, hold MEMORY button while the
respective values are displaying on screen.
