15.3 Special Requirements
a. The panel markings of certain controls on Audio Oscillator TS-382A/U differ from those used on other models. References to con-
trols in the charts apply to the TS-082B/U, TS-382D/U, TS-382E/U, and TS-382F/U. If the TS-382A/U is used to perform these tests,
use the control that corresponds to that given in the charts.
b. The AF-RF switch on Spectrum Analyzer TS-723A/U does not exist on the TS-723B/U or the TS-723C/U. The use of the TS-
723B/U or the TS723C/U for these tests is not affected by the omission of the AF-RF switch.
