O&M visit.

Transceiver 06 had stopped working on 3/9. The display on the CPU board was solid black blocks and the unit was beeping. I rebooted the unit and it came up running properly. However, I replaced the CPU board with a spare and will send the bad unit to Roger.

Checked diagnostics and did timer tag test with all transceivers. All read 100%.

The screens were removed from the pond and the release started on 3/14.
