If enabled, when the CSAT is powered on, the IF and RF outputs will remain
muted for 15 minutes.
Auto Fault Recovery: this defines how a CSAT will react to momentary fault
conditions.
A fault will cause the CSAT to mute and remain muted.
The CSAT will mute when faulted, but unmute after the fault goes away.
The CSAT will automatically lock to an external 5 or 10 MHz reference
independent of the state of this selection. This selection determines whether
or not the Summary Fault Relay is activated if the CSAT loses lock with the
external reference.
The user may edit the Internal 10MHz Reference setting. The value will scroll
between 000 and 255.
NOTE: The Internal Reference is adjusted in the factory to be very accurate
with the default setting of 087. This parameter is made available to
compensate for the long-term frequency drift of the oscillator.
Selecting YES and pressing ENTER will cause the CSAT RTC to be
synchronized to the Modem RTC. (Default is NO.)
