a. Replace the reference module if the error log has the following errors:
- 10 MHz reference
- 16 MHz reference

Verify Launch Time Calculation and Processing
The RF-B! does not process the input message data correctly if there is a time discrepancy
between the RF-B! transmitter controller and the RF-C! controller, or between the RF-B!
transmitter controller and the transmitter.
The RF-B! does not process message data that is received from the RF-C! controller too late or
too early. If the network delay is too short, the RF-B! transmitter controller does not have
enough work-ahead time to launch the page. If the network delay is too long, the RF-B!
transmitter controller input buffers overflow. The RF-B! transmitter controller can buffer up to
64 packets of each kind of packet or up to 60 seconds of data running at full load if only a
single channel is running.
In addition, the RF-B! transmitter controller uses values received from the transmitter to
determine the time for the data to be received by the transmitter. The transmitter will not key
if there is a problem here.
This procedure checks both interfaces for time discrepancy.
1. Connect your FIPS terminal to the FIPS Serial Port on the front panel of the RF-B!
transmitter controller and log into the FIPS session (see Chapter 5, "Operation",
paragraph, "Service Terminal").
