8: You might try to clear the units non-volatile memory, then reconfigure the unit from scratch. From the main menu select 0, then User Parameters, Clr All + Reset. If this fails contact the factory for
an RMA number then return the unit for repair. If the unit will not boot to allow you to select from the screens, you can also clear the memory by powering up the unit while holding in the `NO` key
(but you have to hold the key in until the unit gives its normal three beeps).
9: If you wish to use Drop/Insert, and pass the incoming satellite timing to the downstream network, this is only possible by setting the Rx Insert bearer to "Generate" not "Loopthrough" (Change, Rx,
Baseband, Insert dialogue), and selecting Rx Clock as "Satellite" (Change, Rx, Buff/Clock, Gen' Bearer Clock ). If the downstream equipment requires a terrestrial TS16 Multiframe, you must
configure the modem to use CAS, so the generated bearer has a TS16 multiframe.
