[time-nuts] Troubleshooting SR DG435 Four Channel Digital Delay/Pulse Gen

The DG535 Four Channel Digital Delay/Pulse Generator shows
Ext Clk Error on power up.
The obvious thing to do is turn the rear panel switch to INT, but after 
powering up with the switch in either position the same error message appears.

Connecting an external 10 MHz to the clock input and with the INT/EX switch in 
either position the same error is there.

The on line manual does not have schematics.  Any thoughts?

Have Fun,
