position. (Remember to turn the clock off again any time
the clock is to be laid flat.) It’s worth taking care here as the
batteries can spring up and out of position.
• As the clock is switched on, the Mechanimated habour
scenery and tide dial will immediately move to display High
Tide. From then on , both will move in synchronisation to
update the tide level and forecast every 30 minutes,
following a semi-diurnal (12 hours, 25 minutes) timer.
Setting Your Tide Clock:
• The clock will move to display High Tide every time it is
switched from ‘off’ to ‘on’. The tide state can be manually
adjusted by pressing and holding the demonstration button.
After holding the button down for 5 seconds, the dial and
scenery will start to move. Simply release the button when
the desired tide state is reached. This a quick way to set
your clock initially, however, for a more accurate display we
recommend the below:
• Firstly, consult a tide timetable for accurate timings.
Timetables are usually available in local shops or,
alternatively, go to www.tide-forecast.com and search for
your nearest section of coastline.
• Make a note of when the next conveniently timed High Tide
is and, at that time, switch the clock off and on again . The
clock will then move to exactly High Water at exactly that
time.
• The c lock is now set and can be relied upon to show tidal
indications based on the semi-diurnal timer .
N.B. For maximum accuracy, we recommend this is done at full
moon!
