Connect A Radio Clock To The Dvr - EverFocus eZ.HD ECOR HD 16X1 User Manual

Time Sync Range: The time sync range means the allowed time difference between the DVR and the radio clock.
If the time difference exceeds the entered time sync range (by second), the DVR cannot be synchronized unless
you manually set up the exact same time as the clock or within the time sync range.
For example, if the radio-controlled clock time is 12:00:00 and you enter 30 seconds for the time sync interval,
the allowed time difference between the DVR and the clock should be within 30 seconds which means the DVR
time can be 11:59:30 ~ 12:00:30.
