Appendix F: Redundant Backup F-23
Moseley SL9003Q 602-12016 Revision G
By pressing the RADIO B button, RADIO B now becomes the Master, and the TP64 will
switchover to RADIO B (assuming that RADIO B is “good”).
The default A-Master Logic will then switch to B-Master Logic, as outlined in Tables F-1 and F-
2.
Note: Manual switching of the Master is often used to force the system over to the
standby unit. The user may want to put more “time” on the standby unit after an
extended period of service.
In Hot Standby configurations, this will not buy the user anything in terms of reliability. In a Cold
Standby, the “burn time“ is more significant, since the RF power amplifier device operating life
becomes a factor.

The full array of available settings for the Control and Configuration menus are located in QAM
User Manual. Shown here are the applicable settings for redundant standby systems.
