iii.

In the Oscillator Settings window, set the Holdover Timeout.)

Check on the HOMEscreen that User0 is displayed, with a green STATUS. Note

that the Disciplining State will remain yellow, once Holdover has expired, since

the system time is not synchronized to a reference.

It is also possible to manually set the time via the front panel. Doing so is subject to the

same difficulties as above and should be avoided if possible. Should it become necessary to

manually set the time via the front panel:

Press the TIMING menu button on the front panel.

In the SETTINGS submenu, use the navigation keys to highlight the time. Set the

desired time and press ENTER (the center confirmation button).

Press ENTERagain in the confirmation menu to the right to confirm your manual

clock.

Follow the intructions above to change your reference priority to retain your set-

tings.

Note: Contrary to the User reference discussed above, the Local System

reference can be used for Time, or 1PPS (but not both). For more inform-

ation, see "The "Local System" Reference" on page157.

3.2.1.4 Using Battery Backed Time on Startup

Upon system startup, by default VersaSync will not declare synchronization until one of the

external references becomes available and valid.

This functionality can be overridden by enabling the Synchronize to Battery Backed

Time on Startup, thus allowing the battery backed time to be used as System Time upon

system startup. The Battery Backed Time is also referred to as the time maintained by the

integrated Real Time Clock (RTC)

This will result in VersaSync providing a System Time before one of the external ref-

erences becomes available and valid. This will happen automatically, i.e. without user inter-

vention. As soon an external reference will become available, its time will take precedence

over the battery backed time: The System Clock will adjust the System Time for any time

difference.

Note: The Battery Backed Time is also referred to as the time maintained

by the integrated Real-Time Clock (RTC).
