Note: Please note the polarity when inserting
/
replacing batte
r
ies in the unit,
failure to do so may result in permanent damage. Use good qualityAlkaline
Batteries and avoid rechargeable batteries.
1) Open the battery compartment of the display unit and the transmitter and
place both instruments on a desk with a distance of approximately 1.5
meter. Check that no othe
r
electronic devices are close.
2) Insert 2XAAA 1,5V Alkaline batteries first into the battery compartment of
the transmitter and immediately afterwards 2XAA 1,5 V in the display unit,
observing the correct polarity. When battery is first inserted, the red LED
light will be light up fo
r
3-4 seconds. (If no LED light up or is lighted
permanently, make sure the battery is inserted the correct way or a proper
reset is happened)

Reception o
f
outdoor temperature and RC
C
time
RF (Radio Frequency) Receiving mode
1. When the base station is powered up, all LCD segments will light up fo
r
about 4 seconds afte
r
the “beep”. The weather station begins to registe
r
the
outdoor transmitter, enter RF receiving state fo
r
3mininutes
2. Base station receive the outdoor temperature each 48s. If there is no new
effective signal from the senso
r
in constancy reception failure 6 times, the
outdoor temperature will displays “--.-“
3. Do not press any key before outdoor senso
r
data received, otherwise the
outdoor senso
r
learning mode will be terminated.
4. If the outdoor weathe
r
data is not displayed o
r
if any key is pressed before
the weathe
r
station receives the signal, or when changing batteries you will
need to follo
w
the battery installation procedure again. Please wait 10
seconds before re-insert the battery again to make a prope
r
reset for both
transmitte
r
and receiver.

RCC (Radio Controlled Clock) Receiving Mode
1. During the RF receiving mode, if any key is pressed or time out (3minute), the
unit will ente
r
the RCC receiving mode(maximum 8 minutes). Press any key to
exit the RCC receiving mode.
2. If no RCC signal is detected, the base station will try once every hour to get
an RCC signal until a signal is received. Once the base station receives the
RCC signal it will overwrite the manually set time and date, on the base station
the RCC towe
r
icon will be display.
3. If RCC signal is detected successfully, the base station will continue to scan
fo
r
the RCC signal each day at 2:00, 8:00, 14:00 and 20:00, despite if you
manually set the date and time.
4. The best condition fo
r
reception is at night, between midnight and 6:00am
–
when there is less atmospheric interference.

Note fo
r
Radio Controlled Time:
The DCF WWVB or MSF time signal is an AM modulated time-of-day signal
broadcasted by the Federal Government of Germany, NIST from USA or
National Physical Laboratory. The time base is generated from an atomic
time generator which is accurate to 10 billions of one second.
Please take note o
f
the following fo
r
RCC time reception:
zRecommended distance to any interfering sources like compute
r
monitors
or TV sets is a minimum of 1.5-2 meters.
zWithin ferro-concrete rooms (basements, superstructures), the received
signal is naturally weakened. In extreme cases, please place the unit close
toawindowand/o
r
point its front or back towards the Frankfurt transmitter.

Additiona
l
transmitters
The wireless weather station can receive up to 3 temperature sensors. If you
have purchased additional remote sensors, repeat step 1) fo
r
all extra sensors.
However, ensure that you leave 10 seconds in between the reception o
f
the
last sensor and the set-up o
f
the following sensor. The wireless weather
station will numbe
r
thesensorsintheorde
r
of set-up automatically, i.e. the first
temperature sensor will have the temperature displayed with 1. If only have one
sensor, 1won’t be display.
2.4 Mounting
2.4.1 Base Station
With one foldable leg 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
2.4.2 Remote Sensor
Note: To achieve a true temperature reading, avoid mounting remote senso
r
in

-5-
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.
The outdoor temperature senso
r
bracket can be affixed by screws in 2 ways:

replacement
zWhen the batteries of the outdoor senso
r
are used up, the low battery
indicator appears on the display
zIf battery change happened on remote senso
r
side, then the base station
must be powered up again to re-learn the transmitter.
zPlease use Alkaline Batteries, do not use rechargeable batteries. Please
take note of correct battery polarity.
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
6. 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
neighborhood, 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,is incorrect.
A Check/ Replace the batteries. Also make sure that the remote sensor is
not place near objects that can act as sources of heat or cold.
