The base station has received an instruction to select an invalid channel number

The channel could be invalid for one of the following reasons:
1. The channel number specifies a UHF frequency, but the base station is
VHF, or vice versa.
2. The base station cannot lock onto the specified frequency. To verify if this
is the cause, do a diagnostic test to see if the base station can lock onto the
frequency. See "Determining Synthesiser Lock Ranges" on page
3. There is a problem with the external selection of the channel.
a. Select Monitor > Monitoring > Base Station to determine whether the
channel number is determined by hardware.
b. Select Diagnose > Reciter > Digital I/O to see what the base station
thinks the hardware channel is set to.
c. Select Configure > Base Station > System Interface to check that the
base station is configured to correctly interpret the channel selection. Are
