Home City and Latitude
Indication
Q1
The current Home City and/or
latitude is not indicated when I press
(B).
If the day of the week hand points to "N" after
you press (B), it means that no location
information was acquired during the last
receive operation, so the Home City will not be
shown by the indicator window. If this
happens, pull out the crown to the second
click. This will cause the indicator window to
show the current Home City setting.
