TO INSTALL / REPLACE BATTERY

The solar wall clock can use either the included 1 x AA Alkaline
rechargeable battery (charged by solar panel) or 1 x AA
Alkaline battery (non-rechargeable; not included).

Important: the battery type selection (rechargeable or
non-rechargeable) must be made BEFORE inserting
the battery into the compartment otherwise it may
cause damage to the clock!

INITIAL SETUP

The included alkaline rechargeable battery should provide you
with many years of service. If your battery needs to be
replaced, we suggest you use a fully charged AA Alkaline.

Rechargeable batteries should be fully charged before inserting
into clock. Alkaline rechargeable batteries are
recommended.

If you choose to use a non-rechargeable battery, the battery
switch MUST be moved to the BATTERY position (not the
SOLAR position). In this position, the solar cells do not charge
the battery.

REGARDLESS OF THE TYPE OF BATTERY INSTALLED,
THE BATTERY SWITCH MUST BE IN THE BATTERY
POSITION WHEN THE BATTERY IS INSERTED.

If a rechargeable battery is used, the battery switch should
be moved to the SOLAR position AFTER it is has been
inserted.

To use the included rechargeable Alkaline battery (charged
by solar panel):

1. Remove the insulation tape.

2. Replace battery cover

3. Remove the black protective foil on the solar panel.

DO NOT SET THE CLOCK.

To use a non-rechargeable alkaline battery:

Use switch to

1. Remove the included rechargeable AA battery from the
compartment.

2. Use the switch to select the alkaline battery (see below).

3. Insert 1 x AA, IEC LCR6, 1.5V Alkaline battery into the
compartment, observing the correct polarity (see marking
inside battery compartment.

4. Replace battery cover

DO NOT SET THE CLOCK.

Note: For best performance, batteries should be replaced at
least once every 2 years to maintain the best running accuracy.
Ensure that the batteries used are new and the correct size.

Please help in the preservation of the
environment and return used batteries to an
authorized depot.

SETUP AFTER CHANGING/REPLACING THE
BATTERY

1. After powering up the solar clock, all LCD segments will
light up briefly and it will show the time (00:00), indoor
temperature, date, and indoor humidity.

2. Next, the DCF time code reception will automatically
start. This takes typically between 3 - 5 minutes in good
conditions. If after 10 minutes the DCF time has not been
received, use the “SET” key to enter the set-up mode to
manually set the Time, Time Zone and Date (see manual
settings below). The clock will continue to search for DCF
at 3am and 5am. When the clock has successfully
connected with DCF signal, it will override the manually
set time and date.

Note: When changing the battery:

1. Be careful that it does not spring free from the

contacts.

2.

Always wait at least 1 minute after removing
battery before re-inserting, otherwise start up

RADIO CONTROLLED TIME

The time base for the radio controlled time is a Cesium clock
operated by the Physikalisch Technische Bundesanstalt
Braunschweig, which has a time deviation of less than one
second in one million years. The time is coded and transmitted
from Mainflingen near Frankfurt via frequency signal DCF-77
(77.5 kHz) and has a transmitting range of approximately 1,500
km. Your radio-controlled Weather Station receives this signal
and converts it to show the precise time in summer or
wintertime.

The quality of the reception depends greatly on the geographic
location. In normal cases, there should be no reception
problems within a 1500km radius of Frankfurt.
Once the indoor temperature is displayed on the solar wall
clock, the DCF tower icon in the clock display will start flashing
in the LCD. This indicates that the clock has detected that there
is a radio signal present and is trying to receive it. When the

problems may occur.

19

time code is received, the DCF tower becomes permanently lit
and the time will be displayed.

Daily DCF reception is done at 03:00. If the reception is not
successful at 03:00, then the other reception occurs at 05:00. If
the reception at 05:00 is still not successful, then the next try
will take place the next day.

If the tower icon flashes, but does not set the time or the DCF
tower does not appear at all, then please take note of the
following:

•

Recommended distance to any interfering sources like
computer monitors or TV sets is a minimum of 1.5 - 2
metres.

•

Within ferro-concrete rooms (basements,
superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit close
to a window and/ or point its front or back towards the
Frankfurt transmitter.

•

During nighttime, the atmospheric disturbances are
usually less severe and reception is possible in most
cases. A single daily reception is adequate to keep the
accuracy deviation below 1 second.
