Setting
(Auto Fault Recovery) This defines how a LPOD reacts to momentary fault conditions:
• Disable – LPOD mutes when faulted and remain muted.
• Enable – LPOD mutes when faulted, then unmutes once the fault goes away.
Select an Internal 10MHz Reference setting from 000 to 255.
NOTE: The Internal Reference is set in the factory to be very accurate with the default setting
of 087. This setting is provided to compensate for the long-term frequency drift of the
oscillator.
This sets the threshold for the low forward power alarm/fault. An alarm/fault is triggered if the
forward power drops below the specified value. Set this setting to 00.00 to disable the
threshold.
Select YES and press ENTER to synchronize the LPOD RTC to the Modem RTC. (Default is
NO.)
