READ THIS BEFORE YOU BEGIN

For the best operation,

Insert batteries into the remote transmitter(s) first, and then the receiver. Place the receiver and remote transmitter(s) close together. This will ensure that the receiver

synchronizes with remote transmitter(s).

Place the remote transmitter(s) outdoors within an effective transmission range. Although remote transmitters are weather resistant, it is recommended to place it away from direct

sunlight, rain or snow. This will help to make condition readings more accurate. The transmission range can be affected by the dense walls or electronic interference

in between the receiver and transmitter. Try various set-ups for best results.

GETTING STARTED

STEP 1 : setting the remote transmitters

Remove battery cover and insert 2 AA size batteries to start setup.

The HOUSE CODE will flash for 8 seconds

Select the HOUSE CODE by pressing C/F

The range of House Codes are from "01" to "15". Make sure all transmitters

in your system are set to the same House Code.

Select CHANNEL(1-4) by pressing C/F. This number will be confirmed upon pressing

the SET button, or if no key is pressed for 10 seconds. If only one transmitter is available, it is recommended to leave the CHANNEL be "01”

Humidity & Temperature will display

Select °C or °F of Temperature by pressing C/F and pressing SET. Once setup of remote

transmitter is completed, it will start transmitting at one minute intervals

* Use a different house code if your weather station detects other signals from neighboring sources * Factory default: house code = 01 and channel = 01

STEP 2 : setting the receiver

Remove battery cover and insert 2 AA size batteries. Insert

between terminals observing proper polarity then replace cover.

SYNCHRONIZATION

Automatic Learn Function:

The Learn function begins automatically and runs for

3 minutes when receiver batteries are first installed. Within these 3 minutes, the receiver will beep and display

the temperature & humidity signals from transmitter(s). If the signals are not received within this 3 minutes, the outside temperature and

humidity will show " ". If this is the case, bring the units closer togther or try a different location. Then restart the auto learning function by temporarily removing the batteries from receiver.

Manual-Learn Function (Searching for Remote Signals):

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

Press and hold Channel for 3 seconds in clock display mode

A beep sound indicates that learn function has started

The Outside the symbol will flash and unit

will beep as each remote sensor is detected Temperature & humidity readings of the

remote sensor will display on the receiver.

WEATHER FORECAST

REMARKS:

* After set up, allow 12-24 hours for the Weather Station to operate at a steady state as this will result in a more accurate forecast.

* Common to weather forecasting, absolute accuracy cannot be guaranteed. * If the Weather Station is moved from a location to another location, which is

significantly higher or lower than its initial standing point (e.g from the ground floor to 1st floor of a house), remove the batteries and reinsert them after about 30 seconds. Then re-synchronize with the transmitter with the receiver (see synchronization section) A change in location may affect the transmitter readings of heat and air pressure. Also readings may be inaccurate due to heat escaping from areas of your home with less insulation.

COMFORT LEVEL ICON

The comfort level will be shown based on the data collected from inside temperature / humidity. An indicator will display to show if the level is Comfortable, Normal or Uncomfortable.

Description

It shows that the current environment is at the ideal range for the inside temperature and relative humidity

It shows that the current environment is acceptable

It shows that the current environment contains excessive or inadequate moisture; or is too hot or cold

P.13

LOW BATTERY INDICATION

RECEIVER:

If the low battery symbol " " displays (in the Inside weather display area) then

the receiver batteries are low. A low battery may affect the units performance, for example:

- the LCD display appears faint;

- the transmission range is reduced;

- the data may not display from remote transmitter(s)

You will need 2 x AA batteries for the receiver.

* Note: Changing the batteries in the reciever will cause all settings to be erased.

TRANSMITTER:

If the low battery symbol " " is displayed in LCD display of transmitter, then the remote

transmitter batteries are low. The low battery symbol " " for the transmitter will also display on the reciever

(in the Outside weather area)

The transmitter takes 2 x AA batteries

If a transmitter is exposed to very low

or high temperatures for an extended period of time, the batteries may lose power, which may cause reduced transmission range.
