3. Set up Guide

3.1 Battery install

Note:To avoid operating problems, please take note of battery polarity before/when inserting any

Alkaline Batteries (permanent damaged could be introduced by inserting the battery in wrong

direction). Use good quality Alkaline Batteries and avoid rechargeable batteries.

1) Insert two AAA batteries into the remote sensor

2) Insert three AA batteries into the weather station.

3) Wait 3 minutes or until the outdoor temperature is displayed in the weather station. Do not press any

keys before outdoor sensor data received .

4) Mount the units, ensuring that the receiver can still pick up the signal from the transmitter. To

measure outdoor temperature, place the transmitter outdoors. It will transmit the temperature from its

location.

Every time the remote sensor is powered up (for example after a change of batteries), a random security

code is transmitted and this code must be synchronized with the base station to receive weather data.

Thus if battery change happened on transmitter side, then the receiver must be power up again to

re-learn the transmitter.

After the remote sensor is powered up, the sensor will transmit weather data every 8s for 16 times.After

this learning period is over, then the transmitter will transmit every 48s.

When the base station is powered up, a short beep will sound and all LCD segments will light up for about

3 seconds before it enters into learning mode to learn the sensors security code. After the learning mode,

the base station will start the DCF radio controlled time reception. The receiver will start RCC time

reception period (maximum 10 minutes), and no weather data will be received during this period of time.

If RCC signal can’t be found within1 minutes, the signal search will be cancelled and will automatically

resume every two hours until the signal is successfully captured. Regular RF link will be established once

RCC reception routine is finished.

Note: DO NOT PRESS ANY KEY during the first 3 minutes learning period. After both indoor and

outdoor data are displayed you can place your remote sensor outdoors and set your time (if no RCC

reception is possible). If there is no temperature reading in the indoor station, make sure the units are

within range of each other or repeat the battery installation procedure. If a key is pressed before the

weather station receives the temperature signal, you will need to follow the battery installation procedure

again. Please wait 10seconds before re-insert the battery again to make a proper reset for both

transmitter and receiver.

Note for Radio Controlled Time:

The time and date display is based on the signal provided by the highly accurate government operated

atomic clock. The base station will continue to scan for the radio controlled time signal each day despite it

being manually set. If reception has been unsuccessful, then the radio controlled time icon will not appear

but reception will still be attempted continually. If reception has been successful, the received time and

date will overwrite the manually set time and date.

Note:

When batteries require replacement for the base station, the low battery indicator will light up on the LCD.

Please participate in the preservation of the environment by properly disposing of all used-up

batteries and accumulators at designated disposal points. Never dispose of batteries in a fire as this

may cause explosion, risk of fire or leakage of dangerous chemicals and fumes

3.2 Mounting

1) Base station

With one foldable legs at the back of the unit, the base station can be placed onto any flat surface or wall

mounted at the desired location by the hanging holes also at the back of the unit. It is important to check

that the radio signal can be received before permanently mounting any of the units

2) Remote sensor

Note: To achieve a true temperature reading, avoid mounting remote sensor

in direct sunlight. We recommend that you mount the remote sensor on an

outside North-facing wall; obstacles such as walls, concrete, and large metal

objects will reduce the range.

To wall mount, use 3 screws to affix the wall bracket to the desired wall, plug

in the remote sensor to the bracket.

4.2 Weather forecasting

Sunny Partly Cloudy Cloudy Rainy

The four weather icons Sunny, partly Cloudy, Cloudy and Rainy represent the weather forecasting. There

are also two weather tendency indicators to show the air pressure tendency between the weather icons.

The weather forecasting is based upon the change of air pressure.

4.3 Weather tendency indicator

The weather tendency indicators arrow is 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 last six hours. If the weather is changing, weather tendency indicator (animated

arrows) will be flashing for three hours indicating a weather change is happening. After that, if weather

conditions have become stable and no new weather change condition met,then the arrows will be fixed.

4.4 Examples of changing weather icons:

4.5 Storm warning indicator

The storm threshold can be set to suit the user’s requirement for storm forecasting from 3-9hPa (default

4hPa). When there is a fall over pressure threshold within 3 hours, the storm forecasting will be activated,

the clouds with rain icon and tendency arrows will flash for 3 hours indicating the storm warning feature has

been activated.

Notes to pressure sensitivity setting for weather forecasting:

The pressure threshold can be set to suit the user’s requirement for weather forecasting from 2-4hPa

(default 2hPa). For areas that experience frequent changes in air pressure requires a higher setting

compared to an area where the air pressure is 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.

5. Program Mode

The base station has five keys for easy operation: SET key, ALARM key, MIN/MAX key +key and

SNOOZE/LIGHT key. And there are four program modes available: Quick Display Mode, Setting Mode,

Alarm Mode and Min/Max Mode.

The program mode can be exited at any time by either pressing the SNOOZE/LIGHT key, or waiting for

the 10-second time-out to take effect.
