• The clock automatically attempts to receive a DCF signal six times a
day at 01:22, 05:22, 09:22, 13:22, 17:22 and 21:22.
• Once the clock has received a signal, it syncs with the DCF time
three times per day at 01:22, 03:22 and 05:22. This is sufcient to
keep the time accurate to within one second per day.
• The DCF radio time signal is sent from a transmitter in Mainingen
(near Frankfurt am Main, Germany). It has a range of up to 1500
km, increasing to 2000 km in ideal reception conditions. The DCF
signal contains information such as the exact time and date (with a
theoretical time deviation of one second every million years). There
is no need to set the summer and winter time manually.
c) Manual DCF signal reception
• To search for a DCF signal manually (for example, when you move the clock to a new location
and need the clock to search for a DCF signal again), press and hold the REC button (2) for
3 seconds.
• The clock will stop for approximately 3 minutes while it searches for a DCF signal. Wait until
the correct time is displayed. If the clock fails to receive a signal, the hands will start moving
again. For example, if the time was 13:00 when the clock started to search for a signal and the
search attempt lasted 3 minutes, the clock will display 13:03 when the search attempt ends.
Setting the time manually
• You may need to set the time manually, for example when the clock is not within range of
the DCF signal.
• To set the time manually, press the M.SET button (3) button for three seconds. The second
hand will stop for approximately 5 seconds. Start setting the time while the second hand is
not moving. If the hand starts moving again, press the M. SET button for three seconds to go
back to the manual time setting mode.
• Press the M.SET button briey to adjust the time minute by minute, or press and hold to
adjust the time continuously.
• When you release the M.SET button, the new time will be applied after 5 seconds and the
hands will start moving again.
d) Resetting the clock
• Use the reset function if the clock fails to respond when you press the buttons or if you
encounter other issues (e.g. the clocks fails to receive a DCF signal). Resetting the clock will
delete all previously received DCF data. Before resetting, check whether you can receive a
signal in another location.
• To reset the clock, press the RESET (1) button with a pointed object (e.g. a pen).
• The hands will move to the 12:00 position and the clock will attempt to receive a new DCF
signal.
• Wait 2–5 minutes for the time to be displayed.
e) Discontinuing use
• To discontinue use (e.g. when moving house), reset the clock (see "Resetting the clock" for
details).
The locking pin (4) can only be inserted when the hands are pointing to 12:00.
Remove the battery before inserting the locking pin.

• Do not use strong or abrasive detergents, rubbing alcohol or other chemical solutions, as
these could damage the housing or even impair the functioning of the product.
• The clock does not require any maintenance apart from changing the battery, therefore do
not attempt to dismantle it.
• Remove the battery before cleaning.
• Use a dry, lint-free cloth to clean the product.
• Dust can be easily removed using a soft clean brush.

Troubleshooting
The clock is not synchronising or reception is intermittent:
- The clock is out of range of the DCF transmitter or there is interference from the
surroundings.
- Move the clock to a different location and switch off devices that may be interfering with
reception such as TVs, computers or microwave ovens.
- Avoid placing the clock close to large metal surfaces that may block reception. Metal-
coated windows may also affect signal reception.
- To synchronise the clock, place it by a window with either the front or back facing towards
Frankfurt, Germany.
- Leave the clock switched on overnight to reduce atmospheric interference.
- Reset the clock (see “Resetting the clock” for details).
