| Subject: | TWP/MMCR/C3 - Receiver switch lock-up |
| DataStreams: | twpmmcrspecmomC3.a0, twpmmcrmomC3.00, twpmmcrmomC3.b1
|
| Description: | During the troubleshooting of another intermittent problem, a receiver switch latched up
in an open position making the data unusable. |
| Suggestions: | Do not use the data during this period. |
| Measurements: | twpmmcrmomC3.00: - (Raw data stream - documentation not supported)
