The problem is most likely the A10 assembly (it is
possible, however, that A24 and A38 are both faulty).
First go to paragraph A10.9000. If this does not x the
problem, consider RF.2490, and/or RF.3890.
ILT.2115
The problem is most likely either the A24 or the RF
cables connected to A24. It is possible, however, that the
A10 assembly may be the problem.
If A24 has
not
been replaced, go to RF.2490, otherwise go
to A10.9000.
ILT.2120
The problem is most likely either A38 or the RF cables
connected to A38. It is possible, however, that the A10
assembly may be the problem.
If A38 has
not
been replaced, go to RF.3890, otherwise go
to A10.9000.
ILT.2130
The most likely cause of this problem is the A10
assembly. If this assembly has not been replaced, go to
A10.9000. If this assembly has been replaced, consider
changing the dual modulator (RF.3890) or, for instruments
with Option 006, change the AM modulator (RF.3890).
However, if the problem exists only in low band, try
changing the low band assembly (RF.2490).
