STARTING DCF RADIO RECEPTION

Start a manual reception trial by pressing the “°C/°F” button (B4) until the radio tower symbol
in the display starts ﬂ ashing. A successful DCF-reception overwrites the manual settings of time/
date.

SWITCHTING BETWEEN °C/°F

Brieﬂ y press the button “°C/°F” (B4) in order to switch between the two temperature units
(Celsius and Fahrenheit).

TOGGLING BETWEEN THE 12H /24H MODES

To change between the 12h and 24 h mode, brieﬂ y press the “12/24” button (B3). The 12h-format is
marked with a “AM” ahead of the time for the ﬁ rst half of day, “PM” for the second half.

ALARM FUNCTION

a) Setting the alarm

Brieﬂ y press the button “MODE/SET“ (B2) which switches the display from the current time to

the alarm time.

If the alarm time is shown in the display (“AL“ on the right in the display), keep pressing the

button “MODE/SET“ (B2) until the hours of the alarm time start ﬂ ashing.

By using the buttons “+ 12/24“ (B3) or “- °C/°F“ (B4) you can set the

hours

. For quick adjust-

ment, hold the corresponding button for a while longer.

Conﬁ rm the setting by brieﬂ y pressing the button “MODE/SET” (B2).

The minutes for the alarm time start blinking.

By using the buttons “+ 12/24“ (B3) or “- °C/°F“ (B4) you can set the

minutes

. For quick

adjustment, hold the corresponding button for a while longer.

Conﬁ rm the setting by brieﬂ y pressing the button “MODE/SET“ (B2); the setting of the alarm

time is now ﬁ nished.

Wait a few seconds and the wall clock will switch back to display the time of day (or brieﬂ y

press the button “MODE/SET“ (B2)).

b) Turning the alarm function on/off

Brieﬂ y press the “AL ON/OFF” button (B8). A bell symbol appears in the upper right of the display
if the alarm function is activated.

c) stop alarm signal & “SNOOZE“

If the button “SNOOZE” (B1) is pressed, the alarm signal will be interrupted for about 5 minutes
(a symbol “Zz” is ﬂ ashing between the hours and the minutes) and restarted (snooze function).

The snooze function is repeated seven times.

By pressing any other button the alarm signal is terminated.

SEARCH FOR OUTDOOR SENSOR

Press and hold the button “SEARCH” (B7) until the radio symbol for the outside sensor is ﬂ ashing
(in the lower right corner of the display).

The wall clock now searches for the outside sensor. This can take some time since the external
sensor sends a data packet only every few minutes.

TEMPERATURE ALARM FOR THE OUTDOOR SENSOR

On the wall clock, a temperature alarm for the external temperature can be activated. An upper
and lower temperature range can be programmed and an alarm signal can be emitted when the
values leaves the range.

a) Turning the temperature alarm on/off

Brieﬂ y press the button “ALERT” (B5). When the temperature alarm function is activated, a sym-
bol appears in the lower right of the display (“

”).

b) Programming the temperature alarm

Keep pressing the button “ALERT“ (B5) until the symbol “

“(upper temperature range)

ﬂ ashes.

By using the buttons “+ 12/24“ (B3) or “- °C/°F“ (B4) you can set the upper temperature limit.

For quick adjustment, hold the corresponding button for a while longer.



Example: If “40°C” is set, the alarm signal starts at 40.1°C.

Brieﬂ y press the button “ALERT“ (B5) until the symbol “

“ (lower temperature limit).

By using the buttons “+ 12/24“ (B3) or “- °C/°F“ (B4) you can set the lower temperature limit.

For quick adjustment, hold the corresponding button for a while longer.



Example: If “5 °C” is set, the alarm signal starts at 4.9 °C.

Brief press the button “ALERT“ (B5) in order to ﬁ nish the programming.

c) temperature alarm

When the temperature rises above or falls below the programmed limits, the corresponding sym-
bol blinks and an alarm signal is emitted.

MOUNTING THE OUTDOOR SENSOR

Select an appropriate installation location. It has to be in an area, protected against direct rain and
direct sunlight. Ideally, mount the sensor underneath a roof projection. The sensor can be hung up
e.g. on a nail or a screw by the hook on its back (D5).

Never operate the outside sensor in or under water; it is not water-tight!

RESETTING THE FUNCTIONS (RESET)

If the jumbo wall clock or the buttons should no longer display a function, there is the option of
pressing the “reset button” (B6) with a sharp object (e.g. a nail). Carefully push the sharp object
into the reset opening. All adjusted functions of the wall clock are thereby reset. Begin the setting
procedure again as described above.

INSTALLATION OR SETUP OF THE WALL CLOCK

The wall clock is equipped with a retractable foot on the back (C3) for placing on a table. Set up
the product only on a ﬂ at, stable and sufﬁ ciently sized area.

It is also possible to mount it on a wall. Three notches on the back of the display unit (C1) allow
secure hanging, e.g. on screws or nails.

When setting the clock on a table, it may be necessary to use an appropriate underlay,

since on valuable furniture surfaces impressions or scratch marks are possible.

BATTERY CHANGE INDICATOR ON OUTDOOR SENSOR

The outdoor sensor has a battery change indicator. As soon as the batteries in the outdoor sensor
become weak, the symbol of a struck-through battery “

” appears in the display of the outdoor

sensor next to the temperature display. In this case, the batteries should be changed.

GETTING STARTED

After correctly inserting the batteries, proceed as follows:

In order to let the wall clock recognise the outside sensor more quickly, press the button “TX“

inside of the outside sensor brieﬂ y multiple times. Thus the temperature value is transmitted
to the wall clock via radio and should be displayed within a short time at the lower right in the
clock‘s display.

Inside the battery compartment of the outside sensor, there is the button “°C/°F“ (D4) by

which you can choose the desired indicated unit “°C“ or “°F“ for the display of the external
sensor.

Close the battery lid of the outside sensor (D3) and tighten the four screws (do not apply

force). Make sure the rubber gasket of the battery compartment lid of the outside sensor is
placed in the intended recess.

After a short period the radio symbol for the external sensor stops blinking. Afterwards the

radio tower symbol in the top right of the display (A1) blinks for the search for the DCF signal.

Mount the wall clock as far away as possible from electric/electronic devices, cable, sockets or

metal parts. These have a negative inﬂ uence on the DCF-signal, which could prevent the wall
clock from automatic setting. A bad reception can also be caused by, e.g. metallised insulated
glass, reinforced concrete construction design, coated special wallpaper or an installation in
cellars.

The wall clock is designed to receive and evaluate the so-called DCF signal.

It is a signal which is broadcast from a sender in Mainﬂ ingen (near Frankfurt am Main). Its
range is up to 1500 km and, under ideal reception conditions, even up to 2000 km.

Inter alia the DCF signal contains the exact time of day (accuracy is theoretically 1 second in 1
million years!) and the date.

This means there is no complicated manual setting needed for summer and winter time.





During summer time “DST“ is displayed in the top right (DST = “Daylight Saving Time“ =
summer time).

The initial attempt to receive a DCF signal always happens after the outside sensor reception
attempt. During normal operation the wall clock tries to receive a signal at 3:00 a.m. since there is
much less interference at this time (better reception possible). Further attempts of reception are
conducted at 04:00, 05:00 and 06:00 o’clock.

During the day you can start an attempt of reception by yourself; see section “Start DCF radio
reception”.





The recognition and interpretation of the DCF signal can take 3-5 minutes. Meanwhile do
not move the wall clock. Do not use any buttons.

If there still is no current time/date shown in the display after 10-20 minutes, change the instal-
lation location of the wall clock. Start a new reception search. Press and hold the button “°C/°F”
(B4) until the radio tower symbol starts blinking in the display.





The time and the date can also be set manually, e.g. if there is no DCF signal available, as
on vacation.

SETTING THE TIME MANUALLY

Press and hold the button “MODE/SET“ (B2) until the hours start ﬂ ashing in the display (about

3 seconds).

By using the buttons “+ 12/24“ (B3) or “- °C/°F“ (B4) you can set the

hours

. For quick adjust-

ment, hold the corresponding button for a while longer.
