Selection Setting
AFR
(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, and then unmutes once the fault goes away.
Ref-Adjust
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.
LowFwdPower
Threshold
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.
Sync-Clock
Select YES and press ENTER to synchronize the LPOD RTC to the Modem RTC. (Default is
NO .)
Press ENTER when done.
