2. Press and hold the SET key for about 2 seconds, then the "RESET" icon will
appear at the bottom part of the LCD.
3. Press the + key once, then the stored value will be reset to the current value
and current time.
4. Press the ALARM key to return to normal display mode.
10. Total rainfall amount
The total rainfall measurement is displayed in the fourth section of the LCD, in the unit
of mm or inch. It shows the total rainfall accumulated since last reset of the Weather
Center.
In normal display mode, press the MIN/MAX key 10 times to show the total rainfall
value. The "RESET" icon will also be shown at the same time.

To reset the rainfall reading, press the + key once when the Rainfall value and
"Reset" icon is shown. Then the total rainfall amount will be reset to 0, and the time
updated to current time.
Note:
After power up, the time and date and total rainfall is displayed as "- - -". After time is
adjusted manually, the set time will be shown.
SWITCHING ON/OFF THE BUZZER
User may choose to turn off the buzzer so that when the time alarm is switched on
and activated, the buzzer will not sound but we can still see the alarm icon (((y)))
flashing on the LCD for time alarm.
On the other hand, when the buzzer is turned off and any weather alarm is activated,
the particular weather digits will flash to show user that the weather condition is being
out of the preset threshold value, yet the buzzer will not sound.
To switch off the buzzer:
1. In normal display mode, press and hold the SET key until the icon "BUZZER
OFF" is shown at the right side above the Wind direction scale. The LCD will
change to setting mode.
2. Press ALARM key once to return to the normal display mode. The "BUZZER
OFF" icon will still be shown.

To re-enable the buzzer:
1. When the BUZZER OFF icon is shown on LCD, press the SET key shortly and
the BUZZER OFF icon will disappear.
2. Press ALARM key once to return to the normal display mode. The "BUZZER
OFF" icon will no longer be shown. Then the alarm will sound normally.
LOW BATTERY INDICATOR
The low battery indicator of the Weather Center and the Thermo-hygro sensor will be
displayed at the top and bottom portion of the LCD respectively when the battery
power is low. It is recommended to replace the batteries in all units on an annual
basis to ensure optimum accuracy of the system.
Note:
• After battery change, both the Weather Center and the Thermo-hygro sensor
need to be reset (see note ”Setting up”)
• The History data record will be clear after the battery change.
OUTDOOR TRANSMITTER 915 MHz RECEPTION
The outdoor temperature, humidity, wind data and rainfall are transmitted from the
Thermo-hygro sensor every 4.5 seconds. The Weather Center will then be
synchronized to the Thermo-hygro sensor to receiver outdoor data. The transmission
range (up to 330 feet) of the Outdoor Thermo-hygro sensor may be affected by the
ambient temperature. At cold temperatures the transmitting distance may be
decreased. Please keep this in mind when placing the transmitter.
If the outdoor data are not being received within 30 seconds after setting up (or the
outdoor display shows “- - -“ in the outdoor section of the Weather Center after
consecutive failed attempts during normal operation). Please check the following
points:
45
1. The distance of the Weather Center or transmitter should be at least 5 to 6.5
feet away from any interfering sources such as computer monitors or TV sets.
2. Avoid positioning the Weather Center onto or in the immediate proximity of
metal doors or window frames.
3. Using other electrical products such as headphones, speakers, or cordless
phones operating on the same signal frequency (915 MHz) may prevent correct
signal transmission and reception.
4. Neighbors using electrical devices operating on the 915 MHz signal frequency
can also cause interference.
5. “Visibility” of Weather Center and Thermo-hygro sensor (e.g. through a window)
increases the range.
Note:
When the 915 MHz signal is received, do not re-open the battery compartment cover
of either the transmitter or Weather Center, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then reset all units
(see Setting up above) otherwise transmission problems may occur.
During normal operation, after the outdoor display shows "- - -", the weather station
will change to receive the outdoor data every 15 minutes, until the data is read. Then
the reception period will return to 4.5 seconds.
If no reception is possible despite the observation of these factors, all system units
have to be reset (see Setting up).
POSITIONING
Prior to permanently affixing any of the units, please ensure the following points are
considered:
46
• Cable lengths of the units meet with your distance requirements at the point of
fixing
• Signals from the sensors can be received by the base station at points of
mounting
Weather Center
The Weather Center has been designed to be hung onto wall or free standing with the
foldout stand.
To wall mount
Choose a sheltered place, such as under the eve of a roof.
Avoid direct rain and sunshine.
Before wall mounting, please check that the outdoor
temperature and humidity values can be received from the
desired locations. To wall mount:
1. Fix a screw (not supplied) into the desired wall, leaving
the head extended out the by about 5mm.
2. Hang the Center onto the screw. Remember to ensure
that it locks into place before releasing.

An ideal mounting place for the Thermo-hygro sensor would be the outer wall beneath
the extension of a roof, as this will protect the sensor from direct sunlight and other
extreme weather conditions.
To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in
the Thermo-hygro sensor to the bracket and secure both parts by the use of the
supplied screw and ensure that the cables from the wind and rain sensors are
correctly plugged in otherwise data transmission errors could occur.
Wind Sensor
Firstly, check that the wind-fan and the wind-vane can rotate freely before fixing the
unit. For correct and accurate readings it is important to mount the sensor so that the
front (marked E) is pointing in East-West direction. The wind sensor should now be
