Cannot perform
manual receive.
Auto receive is
turned on, but
the Level 4
receiving
indicator does
not appear on
the Timekeeping
Mode display.
Time setting is

following signal
reception.
Probable Cause
• The watch is not in the Timekeeping
Mode.
• Your current Home City is not one of
the following city codes: ATH, BER,

indicator appears only when time data
and date data (year, month, day) are
both received.
• If the time is one hour off, the DST
setting may be incorrect.
• The Home City code setting is not
correct for the area where you are
using the watch.
What you should do

and try again.
• Select ATH, BER, PAR, or
LON as your Home City.
• Perform manual receive or
wait until the next auto
receive is performed.
• Check to make sure the
watch is in a location where
it can receive the signal.
