[time-nuts] z3816A Problem

I'm having a problem with my Z3816A. The health monitor and self tests show
the unit is fine, but it never moves out of the Power-up GPS acquisition
mode. I've tried several antennas (one of them currently working fine on a
z3801 unit). The z3816A shows it is tracking anywhere from 0 to 6 satellites
but never has the El or Az information filled in. Trying to initialize it
using the :GPS:INIT:POS doesn't work, I get an error message back from the
unit (or a receiver timeout msg). Is there a way to reset to the original
factory settings without using the RS232 interface, or do additional

Any assistance would be greatly appreciated.
