Setting the time zone
The time signal transmitter DCF 77 transmits the time valid in middle-europe, or the Daylight Saving Time
of middle-europe. When using your SONOCLOCK 910 in another time zone or to indicate a local time in
another time zone, you can set the respective time difference as follows:
• Press and hold first the SNOOZE button and press then also the SLEEP button longer as 5 seconds.
– The date indication disappears and e.g. the indication TI -4 appears
in the bottom part of the display.
– The indication ‘TI’ indicates Time Zone and the figure indicates the
time difference in hours between the displayed time and the time
received from DCF 77 (middle-europe).
For normal use in middle-europa (and after putting the set in
operation for the first time) the time difference is installed at 0:
• After entering the time zone adjustment mode, you can now install
the time zone (from -9 to +9 hours) with the +/- buttons. The actual
time indicated in the upper part of the display changes respectively and indicates the selected local time.
A manually set time will not be changed.
• If you wish to indicate e.g. the local time in the U.K. (one hour earlier), you have to install the time zone
at -1 (hour). At a received time (from DCF 77) of e.g. 17.45, SONOCLOCK 910 will now show 16.45,
being the local time in the U.K..
• Please note that when the time indication seems to be wrong, the time zone may have been changed
accidentally.
Manual time setting (if no time signal is received)
1.
Hold down the AL. MODE button for approx. 5 seconds.
This selects the time adjustment mode and the display will flash for
10 seconds max.
If you make no entry within these 10 seconds, the adjustment mode
is aborted.
2.
While the display is flashing, set the quartz clock with the +/- buttons.
If the respective button is kept pressed, time setting will first run at low and then at high speed.
3.
Start the quartz clock exactly to the second by pressing the AL. MODE. button once again.
If this is not done, the clock will start after approx. 3 minutes with the set time.
In the manual time setting mode, the date indication will be suppressed.
4.
Even when setting the clock manually, it will be synchronized by the DCF 77 time signal as soon as
possible (radio tower symbol).
5.
When the clock is manually set, the wake-up functions are retained.
