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.
