How to set the actual Tide state
- Set the actual time.
- Find the current Tide state for your actual location from a trusted data source, website or tide guide.
- Calculate the Tide height for the actual time from your Tide chart. Generally, Tide extremes are approx. 6 hours apart (e.g. if your chart says that HIGH TIDE is 3 hours from your set local time, set your watch to – MID TIDE, rising).
To activate the Tide setting mode press Pusher A or B for approx. 1 second until the hand makes one step. Press the pusher again to move the Tide hand forward step-by-step until the desired Tide state is reached. Keeping the pusher pressed the Tide hand will run continuously until the pusher is released. The Tide setting function is stopped after 10 seconds without actuating the pusher.
Please note:
The Tide hand steps forward every 12 minutes 24.4 seconds, one full turn takes
12 hours, 24 minutes and 24 seconds (one high tide and one low tide). Please
be aware that the Tide state differs from location to location. Changing your
location may require an adjustment of the Tide state. After inserting the
battery, the first pulse for the Tide hand occurs after 60 seconds. Next
pulses follow at the interval of 12 minutes, 24.4 seconds. Adjusting the Tide
state by the pusher has no effect to the interval of the motor pulses, nor
will the Tide function be re-initialized.
