2.Press (either short for incremental advance or long for rapid advance) the T2 button to set the desired hour for your time zone. Please take note of the AM/PM symbols in the digital display.

The proper date will be calculated by the internal microprocessor and at the end of the adjustment the display returns to the default mode showing the date.

5.Replacing the Battery

A low battery is signaled by a blinking “LO” in the digital display.

The battery should be replaced by trained personnel to avoid damage and to maintain the water resistance according to factory specifications.

After battery replacement the hands of your atomic watch must be repositioned to 12 o’clock. The hands can be advanced either incrementally by repeatedly pressing the T2 button or rapidly by holding the T2 button. Pressing the T2 button briefly advances the minutes, holding the button down lets the minute hand move continuously until the T2 button is released. (The minute is also shown in the LCD helping you to set the correct time.) Your watch now uses its integrated quartz movement. Please note in this mode your watch cannot display the date. The time you have set is retained until your watch is able to receive the signal from the WWVB transmitter again. The date will then also be set and displayed in the LCD again.

After your atomic watch automatically receives the WWVB signal the watch will be set to Pacific standard time. You must then either press the T1 button to confirm the time or set the desired time zone as described in 4. Setting the Time Zone.
