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.
Page 3
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. Neve r d i s po s e of b a t t e r i e s i n a f i r e 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 Rain
y
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.
