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, 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.
