POSITIONING THE WEATHER STATION:
The Weather Station comes attached with a removable table stand, which
provides the option of table standing or wall mounting the unit.Before wall
mounting, please ensure thatthe signals of the outdoor temperature can
be received from the desired location. To wall mount:
1. Fixa screw(not supplied) into the desired wall, leaving the head
extended outthe byabout 5mm.
2. Remove the stand bypulling it awayfrom the base ofthe Weather
Station and hang the station onto the screw.Ensure that itlocks
safelyinto place before releasing.
POSITIONING THE OUTDOOR TRANSMITTER
The Temperature Transmitter is supplied with a holder that maybe attached to awall with
the three screwsor double-sided tape (supplied). To attach to
the wall, please follow the stepsbelow:
1. Markthe wall using a pen through the holes in the holder
to obtain the exact drilling position.
2. Drill holes in the wall at the points marked.
3. Screwholder onto wall.
There is also double sided tape included with the wallmount. Thiscan be used instead of
drilling. Please mount this on a smooth surface instead ofa brickone. The surface can,
however, affect the transmission range,for example: if the unit isattached to a piece of
metal, it maythen either reduce or increase the transmitting range. For this reason, we
recommend notplacing the unit on anymetal surfacesor in anyposition where a large
metal surface is in the immediate proximity(garage doors, double glazing etc.). Choosea
sheltered place. Avoid direct rain and sunshine. Before securing in place, please ensure
thatthe Weather Station can receive the signal from the Temperature Transmitter at the
position that you wish to situate them. The Temperature Transmitter clicks in or out of the
holder easily.When inserting or removing the Temperature Transmitter from the wall holder
pleasehold both units securely.
RESETTING:
From time to time, resetting of the Weather Station is necessary. E.g. ifused batteriesneed
to be changed or when the unit ismoved to a newlocation. To reset:
1. Open the batterycover and remove batteries from the both the Temperature
transmitter and the Weather Station.
2. Wait at least 30 seconds and then repeat the procedures specified in Setting up
(above).
REPLACING BATTERIES:
For best performance, replace batteriesonce a year to maintain optimum running accuracy.
Please help inthe preservation of the environment and return used batteries
to an authorized depot.
CARE AND MAINTENANCE:
•Extreme temperatures,vibration and shockshouldbe avoided asthese maycause
damage to the unit and give inaccurate forecasts and readings.
•When cleaning the displayand casing, use a soft damp cloth only. Do not use
solvents or scouring agents as theymaymarkthe LCD and casing.
•Do not submerge the unit inwater.
•Immediatelyremove all low powered batteriesto avoid leakage and damage. Replace
onlywith newbatteries of the recommended size.
•Do not make anyattempts to repair the unit.Return it to its original point ofpurchase
for repair byaqualified engineer. Opening and tampering with the unit mayinvalidate
its guarantee.
•Do not expose the unit to extreme and sudden temperature changes, this may lead to
rapid changesin forecasts and readings and therebyreduce its accuracy.

THE WEATHER FORECASTING ICONS
There are 3weather icons on the second line of LCD which can be displayed in anyof the
following combinations:
Sunny Cloudywith sunnyintervals Rainy
For everysudden or significant change in the air pressure, the weather icons will update
accordinglytorepresent the change in weather. Ifthe icons do notchange, then it means
either the air pressure has not changed or the change has been too slow for the Weather
Station to register.However, ifthe icon displayed is a sun or raining cloud, there will be no
change of icon if the weather getsanybetter (with sunnyicon) or worse (with rainyicon)
since the icons are alreadyat their extremes.
The icon displayed forecaststhe weather in terms ofgetting better or worse and not
necessarilysunnyor rainyas each icon indicates. E.g. if the current weather is cloudyand
the rainyicon isdisplayed, it doesnot mean thatthe product is faultybecause it is not
raining,it simplymeans that the air pressure has dropped and the weather is expected to
get worsebut not necessarilyrainy.
Note:
After setting up, readings for weather forecasts should be discarded for the next 12-24
hours. Thiswill allowsufficienttime for the Weather Station to operate ata constantaltitude
and therefore result in a more accurate forecast.
Common toweather forecasting, absolute accuracycannot be guaranteed. The weather
forecasting feature is estimated to have an accuracylevel of about 75% due to the varying
areas the Weather Station has been designed for use in. In areas that experience sudden
changes in weather (for example from sunnyto rain), the Weather Station will be more
accurate compared to use in areas where the weather is stagnant most of the time (for
example mostlysunny).
Ifthe Weather Station is moved to another location significantlyhigher or lower than its
initial standing point(for example from the ground floor to the first floor ofa house), reset
both unit (see Resetting). Bydoing this, the Weather Station will not mistake the new
location as being a possible change in air-pressure when reallyit is due to the slight change
of altitude. Again, discard weather forecasts for the next12 to 24 hoursas this will allow
time for operation at a constant altitude.
THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendencyindicators (located on
the left hand side of the weather icons).When the indicator points upwards,it means that
the air-pressure is increasing and the weather is expected to improve.When the indicator
points downwards, the air-pressure is dropping and the weather is expected to become
worse.
Taking this into account, we can see howthe weather haschanged and isexpected to
change. For example, if the indicator is pointing downwards together with cloud and sun
icons,then the lastnoticeable change in the weather was when itwassunny(the sun icon
only). Therefore, the next change in the weather will be cloud with rain icons since the
indicator is pointing downwards.
Note:
Once the weather tendencyindicator has registered anychange of weather, it will remain
permanentlyvisualized on the LCD.
OUTDOOR TEMPERATURE READING:
The outdoor temperature reading islocated on the bottom rowof the LCD and will
automaticallybe displayed from when the batteries were inserted. Ifthe outdoor
temperature does not showon the LCDwithin 10 minutes a reset(see Reset below)
becomes necessary. See also item “433 MHz Reception Check” on this.
433MHz RECEPTION CHECK
Ifthe temperature data is not being received 10 minutes after setting up (the displayshows
“- - -”) please checkthe following points:
1. The distance of the Weather Station or Temperature transmitter should be at least
1.5 to 2 meters away from anyinterfering sourcessuch as computer monitors or TV
sets.
2. Avoid placing the Weather Station onto or in the immediate proximityof metal window
frames.
3. Using other electrical products such as headphones or speakers operating on the
same signal frequency(433MHz) mayprevent correct signal transmission and
reception.
4. Neighboursusing electricaldevicesoperating on the 433MHzsignal frequencycan
also cause interference.
Note:
When the 433MHzsignal is received correctly,do not re-open the batterycover of either the
transmitter or Weather Station,as the batteriesmayspring free from the contacts and force
a falsereset. Should this happen accidentallythen reset all units(see Reset below)
otherwise transmission problems mayoccur.
The maximum transmission range is around 25 m from the transmitter to the Weather
Station (in open space). However, this depends on the surrounding environment and
interference levels.Ifno reception is possible despite the observation ofthese factors, all
system units have to be reset (see Reset below).
USING THE WEATHER STATION:
“INDOOR & MIN/MAX” key With each press,the LCD screen will alternate between
the current, minimum or maximum indoor temperature
readings.
