GENERAL
4-48
SINAD set-up incorrect (Error 206) is displayed if the first SINAD reading is lower than the
target. The indicated RF level is unlikely to be correct. Probable causes are:
Initial RF level set is too low.
Radio is disconnected, incorrectly set up or malfunctioning.
Signal generator [CARR ON/OFF] is OFF.
Signal generator carrier is at the wrong frequency.
Signal generator carrier frequency is unmodulated, or modulation is not a 1 kHz sinewave.
[MOD ON/OFF] is OFF.
[SOURCE ON/OFF] is OFF.
If required, check that the correct CTCSS frequency, deviation and level are supplied to the unit
under test.
