metal. Therefore the clock must not be installed in concrete basements or
inside metal cages. In large concrete office buildings or apartments, the
clock should be located near a window for better reception. Also avoid
installing the clock near strong magnetic fields or other devices that
generate a lot of electrical noise (e.g. engines).
7. Setting
Refer to the illustrations on page 2 of this manual.
• Insert batteries in the battery compartment [G] (see §10).
Time setting
• Choose a location for the clock (refer to §5). The clock can be wall
mounted or placed on a desktop using the included stand.
• Wait until the clock receives the synchronization signal from the master
clock. The clock will attempt to contact the master clock for 7 minutes. It
will automatically synchronize once every day at a fixed time (2:00 in the
morning). Note that the received signal is usually stronger at night time.
• During synchronization, the DCF-icon flashes. Once synchronized, the
icon is fixed on the display.
• When the clock doesn’t receive the radio-signal, it will not show the DCF-
icon and starts running showing the wrong time. The clock can be set to
the correct time manually (see below).
• To force wave detection, press and hold the CF- button [F] for ±5s. Note
that frequent use of this feature will shorten battery life time.
• To stop wave detection, press the CF- button [F] for ±2s.
• Default the clock is in 24h format. Press the UP-button [E] to switch to
12h format (AM or PM indicated in front of the time). Press and hold the
CF- button [F] for ±5s to re-synchronize the clock.
Setting the date / clock manually
• The date and time can be set manually when the clock is used in a place
without DCF reception (e.g. a basement) or in case synchronization is
temporarily not possible. Note that because of atmospheric conditions at
night time the DCF signal is stronger and travels further.
• Press and hold the SET-button [C] for ±5s. The display shows the year
(flashing).
• To change the setting, use the UP-[E] or DOWN-[F] button. Press the
SET-button [C] to confirm and move to the next adjustable parameter.
Parameter sequence = year – month – date – day language* - hour –
minutes – time zone offset - exit
* language options are: EN (English), GE (German), DA (Danish), ES
(Spanish), NE (Dutch), FR (French) or IT (Italian).
• If no key is pressed within 8s the clock returns to normal operation.
