instead of the microphone.
If setting "4. Test SG" is OFF, test signal input will not be made.
Pressing SW4 repeatedly changes the test signal as follows.
1. Single tone: AF1 frequency with RE2
2. Two tone: AF2 frequency with RE2
3. Tone burst: AF1 frequency with RE2
Test signal OFF
At the transmission, since the spectrum received by looping back the
transmission signal is displayed on the screen, you can see what kind of test
signal is being output.
· You can use this function to find troubles of the transmitter circuit
(refer to Assembly Manual 3-8. Operation test transmission).
