READ CAREFULLY BEFORE ATTEMPTING ALIGNMENT
1. Set volume control to maximum.
2. Set band switch to MW, SW, AM and FM.
3. Set function selector to radio.
4. Set fine tunning to centre.
5. Set power source voltage to 6V DC.
6. Output of signal generator should be no higher than necessary to obtain an output reading.
