INSTRUCTION MANUAL

P178252GB070

Thank you for your purchase of this delicate Wireless
Weather Station. Once you have inserted the

batteries

the clock will automatically set up and adjust at the change
of Summer/Winter time. Please read these instructions
carefully and keep the manual in a safe place

for future

reference.

The multifunctional weather station is equipped with many
functions providing thorough weather information to you.
The receiver unit has a clear, easy-to-read display that
shows the weather forecast, indoor temperature,
atmosphere pressure, moon phase, time, month, date as
well as the temperature measured and transmitted from
the remote sensors.

The receiver unit retains the minimum and maximum
temperature readings measured at various locations. The
433 MHz technology means no wire installation is required
and you can place the sensors anywhere you like within the
transmission range of 30 meters.

Radio controlled Technology

The radio controlled mechanism fitted to your clock has a
built in receiver which is tuned to the National Physical
Laboratory (NPL) radio signal, called MSF, which is
transmitted from the Anthorn radio station in Cumbria.
The MSF signal is broadcast on a frequency of 60khz and
carries a time and date code that radio controlled clocks
use to set themselves to the correct time.The signal can
cover a distance of about 1000 km from Anthorn.The time
signal received is controlled by cesium atomic clocks and
provides an accurate and reliable source of UK civil time
based on the NPL time scale UTC (NPL).

RECEPTION OF RADIO CONTROLLED TIME SIGNAL

A

The time and date are radio-controlled. The current time
and date are automatically synchronized with the MSF time
transmitted from Anthorn in Cumbria.The Anthorn

signal
transmitter is periodically shut down for scheduled
maintenance resulting in no signal being transmitted. For
dates of the schedule maintenance visit
www.npl.co.uk/server.php?show=ConWebDoc.1001
call the NPL MSF recorded message on (0)20 8943 6493

MSF reception difficulties

Like any receiver your clock needs a good signal to work
properly. The main causes of reception failure are...
* Atmospheric and local interferences
* Interference from electrical equipment e.g. T.V, computers
or radios within 2 meters of the clock.
* Location of the clocks internal receiver within the building
* Reduced local signal due to steel framed structure
* Outside the normal transmission radius

The following suggestion may help improve reception
of the MSF signal:

* Check that the batteries are new and in good condition.
* Check that the batteries are inserted correctly.
* Try rotating the clock as the internal receiver that picks
up the signal is most effective when it is facing directly
towards or away from Anthorn.
* Try moving your clock to a new location away from any
electrical equipment e.g. T.V, computers or radios.
* Remove the battery and insert again after 5.30pm.
Due to local interference the signal is stronger between
midnight and 5am.

5. Repeat the above operation to set the alarm Minute.

6. Press the “ALARM” key to save and exit the setting
mode, or let it exit automatically 30 seconds later
without pressing any key.

NOTE:

1. The alarm will be automatically turned on when you
set the alarm time.

2. Once the Snooze is turned on, the 4-step crescendo
alarm will sound 4 times in 5-minute interval. The alarm
duration is 60 seconds.

3. Pressing the “SNOOZE” key can stop the current alarm
and enter the Snooze mode; while pressing the
