Metal multi-band radio wristwatch
Version 07/12
Item no. 67 20 93
Intended Use
The radio wristwatch is used to read off the exact time. After receiving a valid time signal, it will 
always display the correct time.
This product is spray water-proof. Nonetheless, it must be prevented from coming into contact 
with water. The watch is intended for general daily use and must not be used under conditions 
in which water pressure and temperature severely fl uctuate.
Any use other than that described above will damage the product and can pose other hazards. 
No part of this product may be modifi ed or rebuilt. The safety instructions must be observed 
at all times.

Battery Information
•  Keep batteries out of the reach of children.
•  Please observe the correct polarity (plus/+ and minus/-) when inserting the bat-
tery.
•  Do not leave the battery lying around in the open; there is the risk of it being 
swallowed by children or pets.
•  If swallowed, consult a doctor immediately.
•  Leaking or damaged batteries may cause caustic burns if they come into con-
tact with skin. Therefore, you should use suitable protective gloves.
•  Do  not  short-circuit  or  dismantle  batteries/rechargeable  batteries  and  do  not 
throw them into fi re. There is a danger of explosion!
•  Do not recharge normal batteries. There is a danger of explosion! Only charge 
rechargeable batteries intended for this purpose; use a suitable battery charger.
•  If the product is not to be used for a prolonged period (e.g. in case of storage), 
remove the inserted battery. If batteries are too old, they may leak and damage 
the product and this will invalidate the guarantee/warranty!
•  Please read the chapter "Disposal" to ensure that the batteries and recharge-
able batteries are disposed of without damaging the environment.

What is DCF?
The DCF signal is a coded radio signal that contains the time 
information  of  the  caesium  atomic  clock  of  the  Physikalisch-
Technischen  Anstalt  (Federal  Physical  Technical  Agency)  in 
Braunschweig. 
This atomic clock is so accurate that in theory, a deviation from 
the  actual  time  of  +/-  1  second  is  possible  only  in  a  million 
years. This is a signal which is sent by a transmitter in Main-
fl ingen (near Frankfurt on the Main).
The DCF signal includes the precise time and the date. There-
fore, there is no need to set the time manually (e.g. changing 
the time from standard time to daylight saving time).
They have a range of up to 1,500 km and if transmission conditions are ideal, as high as up to 
2,000 km. Watches equipped with a DCF receiver (radio clocks) can receive and decode the 
DCF  signal  within  this  transmitting  range.  Similar  to  radio  reception,  the  receiving  of  a  DCF 
signal is highly dependent on location, position and interference signals, e.g. from computers, 
television sets or microwave ovens. Another reasons for poor reception can be reinforced con-
crete walls that weaken the DCF signal.
This product can also receive radio signals in other countries. In addition to the DCF in Ger-
many, the watch can also receive the MSF signal in Britain, WWVB signals in the USA and the 
JJY signal in Japan. The particular signal received by the watch depends on the set time zone.
Commissioning
Sleep mode
The  product  may  be  delivered  in  the  so-called  sleep  mode. All  hands  are  still.  The  time  is 
continually updated inside.
Proceed as follows to deactivate sleep mode:
•  Pull out the crown "S2" slightly until you hear a quiet "click".
•  Push the crown "S2" back in until you hear a quiet click. The watch hands will rotate quickly 
until the actual time is reached.
•  Wait until the watch is running at normal speed.
If you do not use the watch for a prolonged period (e.g. a week or more), you can set it to sleep 
mode in order to save the battery. Do this by carefully pulling the crown "S2" until you hear a 
quiet "click". All hands will stop.
 
Do not press any button while the second hand is rotating quickly or not rotating at 
all.
Receiving the radio signal
•  After buying your watch, leave it near a window for 24 to 48 hours to optimise receipt of the 
radio signal.
•  Place the watch fl at and face up on an even, non-metallic surface.
•  Place a non-metallic material such as a small cloth or a small roll of paper between the case 
back and the metal wristband.
 
The clock will regularly attempt to receive a radio signal at approx. 03:00 hrs (night 
time) and to synchronise the time. Even if no radio signal is received at these times, 
the watch will continue to run normally.
If you want to synchronise the time directly with the radio signal, activate the search manually:
•  Keep the key "S1" button depressed for approx. six seconds until the seconds counter stops.
•  The clock will try to receive the radio signal. Once the clock has received the radio signal 
correctly, the seconds counter will rotate, fi rst quickly and then normally again. The current 
time is displayed.
Even if a radio signal is still not received after approx. 20 minutes, the watch will continue to 
run normally. 
 
In addition to the DCF in Germany, the watch can also receive the MSF signal in 
Britain, WWVB signals in the USA and the JJY signal in Japan. The particular signal 
received by the watch depends on the set time zone. If you are travelling into a differ-
ent time zone, set the time zone concerned (see the "Time zones" section).
Check whether a radio signal has been received
Press the "S1" button briefl y. The seconds hand rotates more quickly. The position at which the 
seconds hand stops tells you whether the radio signal has been received correctly:
•  Seconds hand at 12:00 hrs: radio signal received correctly.
•  Seconds hand at 06:00 hrs: radio signal not received correctly.
After a short time (approx. 30 seconds), the seconds hand will rotate normally again.
 
Do not press any button while the second hand is rotating quickly or not rotating at 
all.
AM / PM display
Briefl y press the "S3" key. The seconds hand rotates more quickly. The position at which the 
seconds hand stops tells you whether the current time is AM (Ante Meridiem/before 12:00 hrs) 
or PM (Post Meridiem/after 12:00 hrs):
Seconds hand at 09:00 hrs: the current time is AM.
Seconds hand at 03:00 hrs: the current time is PM.
