SET UP:
Note: This weather station receives only one outdoor transmitter.
Do not mix old and new batteries. Do not mix alkaline, standard, or rechargeable batteries.
1. First, insert the batteries into the temperature transmitter. (see “Install and replace batteries in the
temperature transmitter“).
2. Within 30 seconds, insert the batteries into weather station (see “Install and replace batteries in the
weather station”). Once the batteries are in place, all segments of the LCD will light up briefly. Then
the time (default 12:00) and the weather icon will be displayed. If these are not displayed after 60
seconds, remove the batteries and wait for at least 60 seconds before reinserting them.
3. After inserting the batteries, the weather station will start receiving data from the transmitter. The
outdoor temperature and the signal reception icon should then be displayed on the weather station. If
this does not happen after 3 minutes, the batteries will need to be removed from both units and reset
from step 1.
4. In order to ensure successful 915 MHz transmission, this should under good conditions be a distance
no more than 330 feet/100 meters between the final position of the weather station and the
transmitter (see notes on “Mounting” and “915 MHz Reception”).
INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The weather station uses 2 x AA, IEC LR6, 1.5V batteries. When batteries need
to be replaced, the low battery icon will appear on the LCD. To install and replace
the batteries, please follow the steps below:
1. Lift up the battery compartment cover.
2. Insert batteries observing the correct polarity (see marking).
3. Replace compartment cover.
INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The temperature transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace the batteries,
please follow the steps below:
1. Remove the battery compartment cover at the back of the transmitter.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery compartment cover on the unit.
Note: When changing batteries in any of the units, all units need to reset by following the
setting up procedures. This is because the transmitter at start-up assigns a security code
and this code must be received and stored by the Weather station in the first 3 minutes of power supplied
to it.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure optimum accuracy of these units
(Battery life see “Specifications”).
Please participate in the preservation of the environment. Return used batteries to an
authorized depot.

THE WEATHER FORECASTING ICONS
There are 3 weather icons in the top section of LCD which can be displayed in any of the following
combinations:
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 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 display weather forecasts 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.
Note:
After setting up, readings for weather forecasts should be disregarded for the next 48 hours. This will
allow sufficient time for the Weather Station to collect air pressure data at a constant altitude and
therefore result in a more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting
feature is estimated to have an accuracy level 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
sunny to rain), the Weather Station will be more accurate compared to use in areas where the weather is
stagnant most of the time (for example mostly sunny).
If the weather station is moved to another location significantly higher or lower than its initial standing
point (for example from the ground floor to the upper floors of a house), remove the batteries and re-insert
them after about 30 seconds. By doing this, the Weather Station will not mistake the new location as
being a possible change in air-pressure when really it is due to the slight change of altitude. Again,
disregard weather forecasts for the next 48 hours as this will allow time for operation at a constant
altitude.

THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendency indicators (located on the left and right
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, but when indicator points downwards, the air-
pressure is dropping and the weather is expected to become worse.
Taking this into account, you will see how the weather has changed and how it is expected to change. For
example, if the indicator is pointing downwards together with cloud and sun icons, then the last noticeable
change in the weather was when it was sunny (sun icon only). Therefore, the next change in the weather
will be the cloud with rain icons since the indicator is pointing downwards.
Note: Once the weather tendency indicator has registered a change in the air pressure, it will remain
permanently visualized on the LCD.
INDOOR MIN/MAX TEMPERATURE RECORDS
The current indoor temperature is displayed on the third section of the LCD.
1. Press and release the INDOOR/RESET key repeatedly, the current indoor temperature will alternate
between the MIN/MAX temperature recordings and the current value.
OUTDOOR MIN/MAX TEMPERATURE RECORDS
The current outdoor temperature is displayed on the last section of the LCD.
1. Press and release the OUTDOOR key repeatedly, the current outdoor temperature will alternate
between the MIN/MAX temperature recordings and the current value.
RESET INDOOR AND OUTDOOR MIN/MAX TEMPERATURE RECORDS
In normal display mode, press and hold the INDOOR/RESET key for 3 seconds to reset ALL indoor and
outdoor minimum/maximum records to current values at the same time.
LOW BATTERY INDICATOR
Low battery indicator is displayed on the LCD when the batteries require changing. The low battery
indicator in the indoor temperature area indicates the batteries in the display are low. The low battery
indicator in the outdoor temperature area indicates the batteries in the transmitter are low.

915 MHz RECEPTION CHECK
The weather station should receive the temperature data within 3 minutes after set-up. If the temperature
data is not received 3 minutes after setting up (not successfully continuously, the outdoor display shows “-
- -” ), please check the following points:
1. The distance of the weather station or transmitter should be at least 5 to 6.5 feet (1.5 -2 meters) away
from any interfering sources such as computer monitors or TV sets.
2. Avoid positioning the weather station onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the same signal
frequency (915 MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 915MHz signal frequency can also cause
interference.
Note: When the 915 MHz signal is received correctly, do not re-open the battery cover of either the
transmitter or weather station, as the batteries may spring free from the contacts and force a false reset.
Should this happen accidentally then reset all units (see Set up above) otherwise transmission
problems may occur.
The transmission range is about 330 feet/100 m from the transmitter to the weather station (in open
space). However, this depends on the surrounding environment and interference levels. If no reception is
possible despite the observation of these factors, all system units have to be reset (see Set up).
POSITIONING THE WEATHER STATION:
The weather station may be hung onto wall easily or free standing.
Free standing
With the detachable stand, the weather station can be placed onto any flat surface.
To wall mount
Before wall mounting, please check that the outdoor temperature value can be received
from the desired locations.
1. Fix a screw (not supplied) into the desired wall, leaving the head extended out by about
5mm.
2. Remove the stand from the weather station by pulling it away from the base and hang
the station onto the screw. Remember to ensure that it locks into place before releasing.
POSITIONING THE TEMPERATURE TRANSMITTER:
Choose a sheltered place. Avoid direct rain or sunshine.
The transmitter is supplied with a holder that may be attached to a wall with the two screws
supplied. The transmitter can also be position on a flat surface by securing the stand to the
bottom of the transmitter.

To wall mount:
1. Secure the bracket onto a desired wall using the screws and plastic anchors.
2. Clip the remote temperature sensor onto the bracket.
Note:
Before permanently fixing the transmitter wall base, place all units in the desired locations to
check that the outdoor temperature reading is receivable. In event that the signal is not
received, relocate the transmitter or move the units slightly as this may help the signal reception.
CARE AND MAINTENANCE:
Extreme temperatures, vibration and shock should be avoided as these may cause damage to the
unit and give inaccurate forecasts and readings.
Precautions shall be taken when handling the batteries. Injuries, burns, or property damage may be
resulted if the batteries are in contact with conducting materials, heat, corrosive materials or
explosives. The batteries shall be taken out from the unit before the product is to be stored for a long
period of time.
Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new
batteries of the recommended type.
When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scouring
agents as they may mark the LCD and casings.
Do not submerge the unit in water.
Special care shall be taken when handling a damaged LCD display. The liquid crystals can be
harmful to user's health.
Do not make any repair attempts to the unit. Return them to their original point of purchase for repair
by a qualified engineer. Opening and tampering with the unit may invalidate their guarantee.
Never touch the exposed electronic circuit of the device as there is a danger of electric shock should
it become exposed.
Do not expose the units to extreme and sudden temperature changes, as this may lead to rapid
changes in forecasts and readings and thereby reduce their accuracy.
