0 Option)
You can use this feature to synchronize the time on the DL850E/DL850EV with the GPS (Global Positioning
System) on the basis of a GPS signal received through the GPS antenna.
This feature has two conditions: Unlock and Lock.
When a GPS signal is properly received, the DL850E/DL850EV enters into the Lock condition and acquires time
information.
Turning the Time Synchronization Feature On and Off (Time Synchro)
You can select whether to use a GPS signal for time synchronization.
Time Difference from Greenwich Mean Time (Time Diff. GMT)
This is the same feature as the time difference of the date and time settings. However, the time is set in 15
minute intervals.
