Auto Synchronization
chronizes overnight as the radio signal is the strongest in
the early morning. You can leave the watch to synchronize
at a later time or you can set the watch manually. As noted
below, a manually set watch still attempts to synchronize
itself automatically every 2 hours for the first 3 days.
Note:
Regarding forced synchronization and halting of
synchronization, if you want the watch to attempt synchro-
MODE
nization, press and hold the button. This activates
the synchronization process. If the watch is in synchroni-
MODE
zation mode, then press and hold button to halt
synchronization.
