[time-nuts] TrueTime XL-AK Issues

[paul swed]

Wow
They actually came up. A site survey can take some 20 hours.
There should be some LED indicator that says the status is locking.
Let them run a day or two.
If there is a LI battery to retain information that may be long gone.
Replacing that would give you a fatser start.
Had to do this on some Odetics receivers.
Good luck
Paul.
