1. Radio technology –The most up-to-date way to keep time
5,000 years have passed since timekeeping began with sundials.In the interim
there have been water clocks, the mechanical clocks of the 13th century and
quartz watches. Now we have the radio-controlled watch.
A watch that in good reception conditions never goes wrong and never has to
be set.The Junghans radio-controlled watch is absolutely precise, as it is linked
by radio frequency to the time control systems of the most accurate clocks in
the world.
For Europe this is the Caesium Time Base at the Physikalisch-Technischen
Bundesanstalt in Braunschweig (Germany’s Institute of Natural and
Engineering Sciences).
For North America it is the U.S. Commerce Department’s Caesium Time Base at
the National Institute of Standards andTechnology (NIST) in Boulder, Colorado.
For Japan the Ministry of Post and Telecommunication’s Caesium Time Base at
the Commercial Research Laboratory (CRL).
All of these clocks are so accurate, that they are expected to deviate by no more
than 1 second in a million years.

1.1 Usable time signal transmitters
Your Junghans multi-frequency radio-controlled watch is capable of fully auto-
matic reception of time signals from the following transmitters:
– DCF77 in Mainflingen (Frankfurt am Main) for Europe
– WWVB in Fort Collins, Colorado (USA) for North America
– JJY40 on Mount Otakadoya (near Tokyo in the North East of the country)
for Japan
– JJY60 on Mount Hagane (in south western Japan) for Japan,the east
coast of China (Shanghai), für South Korea and parts of Taiwan.
With good reception, the Junghans multi-frequency radio-controlled watch
thus always shows the perfectly correct time within any of these four trans-
mission areas. The watch automatically synchronises itself overnight with the
DCF77, WWVB, JJY40 and JJY60 time signal transmitters.
If reception fails due to interference (e. g. stormy weather, electrical appliances
or dimmer switches), the Junghans multi-frequency radio-controlled watch
will launch renewed attempts to pick up the signal fully automatically the fol-
lowing night.
It is also possible to use a ‘transmitter call’ to synchronise the time manually,
for example at a location where reception conditions are better.
The latest time information received is stored in a time memory. This original
time continues to be kept using a high-precision 32 kHz quartz movement
until the time is synchronised again.The radio-controlled time synchronisation
of your Junghans multi-frequency watch not only ensures an always precise
display of the time, but – given good reception – also takes care of switching
from winter to summer time, and vice versa, fully automatically (at night).
Please note that this does not apply to the USA’s WWVB time signal transmit-
ter (see section 3).
If you travel to a country in a different time zone, the time adjustment facility
on your Junghans multi-frequency radio-controlled watch makes it easy to
switch to the appropriate local time.

2. Readiness for use
So that your watch is always ready for use, you should make sure that it does
not run low on power.The watch regularly checks to see if it has sufficient bat-
tery power. If it no longer has enough (e.g. the battery has run out or ambient
temperature is too low, which impairs battery performance), the second hand
stops at the 12 o’clock position. A battery symbol and the current second also
appear on the LCD display. If the battery does not recover (e.g. through an
increase in the ambient temperature), you should take the watch as soon as
possible to your authorised specialist to have the battery changed,or send it to
have this done to the Junghans Service Centre.
Battery type: CR 1632
Typical life: Approx. 2 years
Please ensure that the battery is disposed of properly in accordance with
statutory regulations.
3. Automatic time synchronisation
Daily, fully automatic time synchronisation takes place overnight. While the
signal is being received the second hand temporarily stops in the 9 o’clock
position. During this time, the LCD display is turned off (nothing is shown).
After the time has successfully been automatically synchronised, the original
mode is again shown in the display. The date is always advanced automatical-
ly by the time signal. This process also takes the 29th of February into account
in leap years.
If all of the attempts at picking up a signal lead to no clear synchronisation, the
reception indicator goes up by 1 (see also the description of ‘Reception indica-
tor’ mode in section 5.5). Any further days without synchronisation are added
to this. During any such days without synchronisation, your watch continues
For the USA’s WWVB time signal transmitter the following specific feature
applies:
After a successful transmitter call or battery change (restart), your Junghans
multi-frequency radio-controlled watch always reads in Pacific Standard
Time.
Due to the non-uniform changeover from summer to winter time and the
differing time zones in the individual US states, you are given the opportu-
nity to adjust winter time, summer time and time zone settings (see 5.7)
manually.
If, due to where you are, the time zone or summer / winter time that you
have set differs from PST, it is nevertheless retained during any subsequent
transmitter call or automatic synchronisation.

to run with the accuracy of a quartz timepiece, using the internal time
memory. As soon as the signal is picked up again successfully, your watch is
synchronised and the reception indicator is reset to ‘0’.
Recommendation: To ensure the best possible conditions for night-time recep-
tion of the synchronisation signal, you should ideally not wear your watch at
night and you should, if possible, not put it down near to electrical appliances,
mobile or cordless phones.
4. Functions
The Junghans Multi-frequency Alarm Chronograph features a variety of func-
tions.These are indicated in the two areas of the LCD display and are operated
via the four buttons on the left and right of the watch case.
Winder lock:
On the winder of your radio-controlled watch there is a black line that acts as
a marker. If this line is aligned as an extension of the 3 o’clock position, all of the
watch button functions are enabled. If the mark is not visible as an extension
of the 3 o’clock position, the button functions are disabled.

The date and day of the week remain showing in the upper part of the LCD
display.The display can be shown in German, English or French. How to set the
relevant language is described in section 5.8.
The LCD display continues to show the selected mode until another mode is
selected via the ‘MODE’ button.
5. Description of watch functions and how to use them
5.1 – Chronograph stopwatch function with split times
Press the ‘MODE’ button repeatedly
until you reach ‘CHRONO’ mode.
On the display you will see hour,
minute, second and tenths of a
second.
4.1 Base mode
In base mode the LCD display shows the date and day of the week in the top
section and the digital time in the bottom section. The latter is the 2nd time.
Depending on the setting in use, this thus either reproduces the analogue
time or displays another, user-defined time.
In this mode the watch can be adjusted via the following buttons:
xRESET
xSET+
xSET–
In order to avoid changing any settings accidentally, you can use the winder
lock. You will find a description of this function on the inside cover of your
watch instructions.
4.2 Other functions
The following functions can be accessed sequentially via the ‘MODE’button:
1– 2nd time
2– Reception indicator
3– 1st time
4– Chronograph stopwatch function with split times
5– Alarm
6– Count-down / count-up timer

4544
The chronograph is started and
stopped again using the ‘SET+’
button. When the chronograph is
running,‘ON’is displayed in front of
the ‘CHRONO’ item on the menu.
Pressing the ‘RESET’ button resets
the counted time to ‘0:00:00.0’. The
reset function can only be used
once the chronograph has already
been stopped. When the chrono-
graph is running, the current split
time can be displayed by pressing
the ‘SET–/SPLIT’ button for about
5seconds. The chronograph conti-
nues running in the background.
5.2 Alarm
Press the ‘MODE’ button repeatedly
until you reach ‘ALARM’ mode.
You set the alarm time by using the
‘SET+’ and ‘SET–’ buttons. You can
adjust the time by the minute by
pressing either button briefly or
adjust it in fast forward or fast
rewind mode by holding the rele-
vant button down for longer.

4746
You use the‘ON/OFF’button to turn
the alarm on or off. If the alarm is
active, the indicator ‘ON’is shown in
front of the ‘ALARM’ menu item on
the LCD display. When the alarm
time is reached an acoustic signal
sounds.
Once the alarm has gone off, it is no
longer active. If you want to use the
alarm again, please set it and acti-
vate it as described above.
5.3 Count-down timer
Press the ‘MODE’ button repeatedly
until you reach ‘TIMER’ mode.
You set the timer using the ‘SET+’
and ‘SET–’ buttons. If you press
briefly the display moves a second
at a time. If you press for longer, the
setting changes rapidly.
You use the‘ON/OFF’button to turn
the timer on or off. If the timer is
active, the indicator ‘ON’is shown in
front of the ‘TIMER’ menu item on
the LCD display.
When the timer gets to 0:00:00’, an
acoustic signal sounds.

4948
5.4 2nd time
The 2nd time function gives you the option, independent of the analogue time,
to have another time shown on the LCD display (e.g. if you are on holiday in
another time zone and want to see the time at home).
Press the ‘MODE’ button repeatedly
until you reach ‘2nd TIME’ mode.
Second time is set in 30-minute
steps using the ‘SET+’ and ‘SET–’
buttons.
You can protect this function from
accidental adjustment by pressing
the ‘RESET’ button for more than
3seconds. A ‘lock symbol’ on the
LCD display then indicates that the
function is ‘protected’.
To enable yourself to make a new setting, press the ‘RESET’ button for over
3seconds.

5150
5.5 Reception indicator
You can tell from the reception indicator whether your watch has synchronised
with the signal from the synchronisation transmitter.
Press the ‘MODE’ button repeatedly until you reach the reception indicator, a
‘’.The abbreviation for the language that is currently set appears next to
the date in the top section of the LCD display, while the bottom part shows the
transmitter from which the signal was received and another number, the
reception indicator.
If the reception indicator is showing‘0’, the watch has picked up the signal pro-
perly during overnight synchronisation. The numbers ‘1-9’show for how many
days the watch has been unable to synchronise automatically due to poor
reception conditions.The next time that synchronisation is successful the indi-
cator will revert back to ‘0’.
5.6 Manual time synchronisation (transmitter calls)
Your Junghans Multi-frequency Alarm Chronograph can also be synchronised
manually, by performing what is called a ‘transmitter call’.
To do so, press the ‘SET+’ button for more than 3 seconds while in reception
indicator mode.
The hands start to move and come to a stop at the 12 o’clock position. As soon
as the reception stage begins (i.e. when the hands are in the 12 o’clock position)
the indicator on the display goes out.
While the signal is being received, please keep your watch still or put it down.
When the watch has successfully picked up the time signal (after 2–3 minu-
tes), the hands automatically move to the correct time and the LCD display
switches back to what it was showing before. You are also able to abort the
> 3 sec.

5352
manual synchronisation process, as soon as the hands are in the 12 o’clock posi-
tion.To do this,you press the‘SET+’button. The hands then reset themselves to
the original time.
Whenever manual synchronisation has been performed successfully, the
reception indicator reverts to ‘0’. If the transmitter call was not successful, the
reception indicator does not change and the hands reset themselves to the
time that was displayed before the transmitter call.
5.7 Setting the time zone
If you travel to a country with a different time zone, you can set the current
local time as the second time shown in the lower section of the LCD display
(see section 5.4), and/or adjust the analogue time display to what the time is
locally.
To do so, press the ‘MODE’ button
repeatedly until you reach ‘1st TIME’
mode. The analogue time being
shown is now also shown digitally
in the bottom part of the LCD
display.
You adjust the time zone setting,
and thus also the position of the
hands to the time in that zone, an
hour at a time by pressing the
‘SET+’ (plus 10 hours) and ‘SET–’
(minus 13 hours) buttons. If neces-
sary, the date is also changed auto-
matically during such adjustment.
You can protect this function from
being altered accidentally by pres-
sing the ‘RESET’ button for more
than 3 seconds. A ‘lock symbol’ on
the LCD display then indicates that
the function is ‘protected’.
To enable yourself to make a new
setting, simply press the ‘RESET’
button for over 3 seconds.

5554
5.8 Setting the language (day of the week display
Your Junghans Multi-frequency Alarm Chronograph is shipped with the lang-
uage for the day of the week display set to German. Switching the setting to
English or French is done in reception indicator mode (i.e. with the ‘ ’
displayed).
To change the day of the week
display to another language, press
the ‘MODE’ button until you reach
‘Reception indicator’ mode.
Press the ‘RESET’ button for longer than 3 seconds. The ‘DE’symbol starts to
flash. Using the ‘SET+’or ‘SET–’button, you can now set the language you want.
DE = German
En = English
FR = French
If you press the ‘MODE’ button and move on further, you can then use the
‘SET+’ or ‘SET–’ button to set the date format to either day/month or
month/day.
If you move on still further by pressing the ‘MODE’ button, you can again use
the ‘SET+’ or ‘SET–’ button to change from a 24-hour to a 12-hour display. The
latter is indicated on the LCD display by ‘AM’or ‘PM’.
6. Restart / getting started
Following a change of battery, your watch will automatically begin a restart
routine. After you insert the battery, the hands will move to the 12 o'clock posi-
tion and your watch will start trying to pick up the time signal. During this pro-
cess the LCD display is switched off. After a few minutes, if the reception pro-
cess has been successful, the watch automatically sets itself to the correct
time.
xOn successful reception of the DCF77 transmitter, German local time is
shown, the reception display for the DCF77 is activated on the LCD and the
date is displayed with the day of the week in German.
xOn successful reception of the WWVB transmitter, the Pacific time zone is
shown, the reception display for the WWVB is activated on the LCD and the
date is displayed with the day of the week in English.
xOn successful reception of the JJY40 or JJY60 transmitter, Japanese local
time is shown, the reception display for the JJY40 or JJY60 is activated on the
LCD and the date is displayed with the day of the week in English.
If the watch fails to pick up a signal within 30 minutes, the reception process
is aborted in order to save power. However, your Junghans Multi-frequency
Alarm Chronograph will automatically start the signal reception process again
at a later time. You can also manually attempt to pick up a signal at any time
using a transmitter call.

5756
If you are too far away from a transmitter for any attempt at reception to
succeed, you will need to set your watch to the current time manually (this is
called a manual start). It will then run like a normal quartz watch.
6.1 Manual start
After an unsuccessful restart (at least 30 minutes with no reception from any
transmitter), you can initiate the manual start routine. This can also be done
during the restart process.
After the hands have reached the
12 o'clock position in the restart
routine, please press the ‘MODE’
and ‘SET–’ buttons at the same
time.
If the watch is in ‘manual start’ mode an ‘H’for starting by ‘hand’ is shown on
the LCD display.
The potential parameters to be set now flash.These can be set using the ‘SET+’
and ‘SET–’ buttons. Please confirm each setting by pressing the ‘MODE’ button.
xYear
xMonth
xDay
x12-hour display

When setting the second it is important to confirm this at the ‘top’ of the
minute so that the correct time is shown.
Once you have confirmed the time, the hands move automatically to the
correct position.
