2. Installation
2.1 Installing the Batteries
Note: Please note the polarity when inserting/replacing batteries in
the unit, failure to do so may result in permanent damage. Use good
quality Alkaline Batteries and avoid rechargeable batteries.

1) Insert two AAA batteries into the remote sensor. 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.
2) Insert two AA batteries into the weather station. When the base
station is powered up, a short beep will sound and all LCD segments
will light up for about 4 seconds before it enters into learning mode
to learn the sensors security code. 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 remote sensor side, then the base station must be
powered up again to re-Iearn the transmitter.
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
. The wireless weather station can receive up to 3
temperature sensors. If you have purchased additional remote
sensors, repeat step 1) for all extra sensors. However, ensure that
you leave 10 seconds in between the reception of the last sensor and
the set-up of the following sensor. The wireless weather station will
number the sensors in the order of set-up, i.e. the first temperature
sensor will have the temperature displayed with
CH1
. If you only have
one sensor,
CH1
won't be displayed.
4) After the learning mode, the base station will start the radio controlled
time reception. The receiver will start RCC time reception period for
10 minutes maximum, and no weather data will be received during
this period of time. If RCC signal can't be synchronized with the
base station within 1 minute, the signal search will be cancelled and
will automatically resume every hour on the hour until the signal is
successfully captured. Regular RF link will be established once RCC
reception routine is finished.
5) 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.

Note: DO NOT PRESS ANY KEY
on the base station until the first
set of data is displayed on the LCD. This ensures that the base station
has synchronized with the sensors and that the system is now
functioning. 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 10 seconds before re-inserting 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 at 2:00. 8:00. 14:00 and 20:00 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:
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.
2.2 Mounting
2.2.1 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 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.

2.2.2 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.

3.2 LED backlight
The backlight is automatically switched ON when any key is pressed.
The backlight will be switched on for approximately 5 seconds before
automatically switching OFF.
3.3 Weather forecasting
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.
For every sudden or significant change in the air pressure, the weather
icons will update accordingly to represent the change in weather. If
the icons do not change, then it means either the air pressure has not
changed or the change has been too slow for the wireless weather
station to register. However, if the icon displayed is a sun or raining
cloud, there will be no change of icon if the weather gets any better
(with sunny icon) or worse (with rainy icon) since the icons are already
at their extremes. The icons displayed forecasts the weather in terms of
getting better or worse and not necessarily sunny or rainy as each icon
indicates. For example, if the current weather is cloudy and the rainy
icon is displayed, it does not mean that the product is faulty because it
is not raining. It simply means that the air pressure has dropped and the
weather is expected to get worse but not necessarily rainy.

3.4 Weather tendency indicator
The weather tendency indicators arrow is located beside 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 upward arrow means that the air pressure is increasing and the
weather is expected to become better. The downward arrow means that
the air pressure is decreasing and the weather is expected to become
worse. The tendency indicator arrow will not show up while the pressure
without change within 3 hours.
3.5 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 3hPa). 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.
3.6 Storm warning indicator
Once the required pressure sensitivity has been set, the storm-warning alert
will be activated if the pressure changes by the required amount over a
three-hour period. The forecast icons will indicate that a storm-warning has
been activated by displaying the rain icon alongside flashing downward
arrows for three hours.
4. Program Mode

Troubleshooting
Q 1. No signal from remote sensor
A There can be many reasons for this, the following steps should
help you troubleshoot this problem.
1.1 Make sure that the batteries in the remote sensor are not
depleted.
1.2 Reduce the distance between transmitter and receiver
1.3 Remove the batteries from the base station and the remote
sensor and reset the weather station in the right order as described
in section 2 of this manual.

1.4 This problem could also be a result of radio interference in your
neighbourhood, try relocating the sensor and the base station
Q 2. Remote sensor drops off intermittently
A Possible interference from other sources, try relocating the sensor
or the base station. Radio device operation on the same frequency
can also cause interference.
Q 3. Temperature, humidity or the pressure is incorrect.
A Check/Replace the batteries. Also make sure that the remote
sensor is not placed near objects that can act as sources of heat or
cold. Adjust the relative air pressure value from a reliable source
such as TV or radio
