The Braun AW 200 wrist watch is
automatically set and controlled by
the long wave radio signal of the
German time transmitter DCF 77
(Central European Time). The trans-
mitter is situated in Mainflingen,
24 km south of Frankfurt/Main. The
DCF 77 transmitter uses the caesium
atomic clock of the Federal Physical
Technical Institute in Brunswick as
its time source.
Reception
The radio signal can be received
within a 1000 km radius of the trans-
mitter, depending on the position
of the clock and local conditions.
Interference can occur as with any
radio receiver, for example from
external factors (computers, TV sets
and radios), geographical obstacles
(mountains and valleys), or metal
paneling inside or on buildings.
Functions
Resetting seconds/date
(B)
Briefly press button

to switch
between the seconds or date setting
in the display.
Reception of signal
(C)
Your AW 200 synchronises itself
automatically on a daily basis with
the time transmitter DCF 77. This
normally happens between 2 and
3 o’clock at night. To verify if the last
reception process was successful,
briefly press button
2
. The display
will show one of the following
symbols:
= last signal successfully
received
= last attempt to receive
signal failed
Manual reception of signal
(D)
Manual reception is only necessary
in exceptional cases: For example,
when returning from a trip outside
the transmission range. Briefly press
button
2
, so that one of the above
mentioned symbols appears in the
display. Then press and hold the
same button for two more seconds.
The reception is activated when «00»
flashes in the display.
However, as the Braun AW 200
continues to work like a high-preci-
sion quartz watch, inside or out-
side the transmission range, any
deviation will be minimal and will be
corrected when the next synchroni-
sation takes place.
Checking the reference
position
(E)
The reference position is very impor-
tant because this tells the electro-
nics where to set the clock hands. If
the watch is subjected to extreme
exposure (highly electromagnetic
field, extreme temperature fluctua-
tions or strong shock to the watch
casing), the reference position can
change.
To check the reference position,
press button
2
for 2 seconds. The
display will show a flashing «12»
while the hands of your watch will
