SETUP

Automatic Learn Function:

Learn function executes automatically and runs for approximately

3 minutes when batteries are first installed in the receiver.

Within these 3 minutes, receiver picks up the temperature & humidity signals from remote sensor and displays the readings.

OUT

Manual-Learn (Searching for Remote Signals):

If a new remote sensor is added or if signal is lost (outdoor display blinking), learn function must be executed again.

Press and hold CHN for 3 seconds to start

Beep sound indicates that

learn function has started

'Outside' symbol will flash and

unit will beep as each remote sensor is detected

WEATHER DISPLAY

animated weather forecast symbols

This weather station is capable of detecting barometric pressure changes, and based on the data collected, can predict the weather for the next 12 to 24 hours. The effective range covers an area of 30 – 50km.

Sunny

Cloudy

Raining

Snowing

Freeze Warning

Storm Alert

* Storm symbol will flash to warn of thunderstorm.

About Freeze Warning

* Snow symbol will flash to warn of 'freezing'. * Activated when Channel 1's temperature is between -1.9 C and +2.9 C * Snow will appear solid if and when Channel 1's temperature falls below -1.9 C.

Note:

* Remote sensor Channel 1 will be used for weather indication.

P.10

REMARKS:

* After setting up, reading for weather forecasts should be discarded for the next 12-24 hours. This will allow sufficient time for the Weather Station to operate at a constant altitude and therefore result in a more accurate forecast.

* Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature is estimated to have an accuracy level of about 75% due to the varying areas the Weather Station has been designed for use in.

* If the Weather Station is moved to another location significantly higher or lower than its initial standing point (e.g from ground floor to 1st floor of a house), remove the batteries and reinsert them after about 30 seconds. By doing this, the Weather Station will not make mistake of new location being a possible change in air pressure. Again, discard the weather forecasts for the next 12-24 hours as this allow time for operation at a constant altitude.

signals to update the clock.

The temperature measurement of

remote sensor and receiver does not match.

Temperature reading of outdoor

iii

remote sensor seems to high.

Receiver is no longer receiving

remote sensor signals or display

solution

Place the clock away from metal objects or

electricalappliances such as TVs, computers, monitors, etc.

Wait for about 1-2 minute to ensure the remote

sensor and receiver are in phase. Otherwise, re-synchronize receiver by holding CHN for 3 seconds until a beep is heard.

Ensure the remote sensor is out of direct sunlight,

iii

and away from sources of heat.

- Repeat the learning procedures.

- Temperature may be below -30C.

- Batteries in remote sensor may need changing.

- Move remote sensor closer to the receiver.

- Make sure remote sensor is away from sources of electrical disturbance.
