Notes for Tables 6-9 and 6-10:
1. Bias control and ground delay settings will track each other from 50 ms to 750 ms. Above 750 ms, the ground delay varies in non-
proportional steps:
Bias Ground
800 ms 2 s
850 ms 5 s
900 ms 10 s
950 ms 15 s
1000 ms 30 s
2. When this parameter is enabled and the [ENT] key is pressed, the Display Controller requests that the PROGRAM mode security code
(.248) be entered. Once it is, all parameter values will be reset to the default values listed above. These are the values the parameters
are set to before the RFL 9300 leaves the factory.
