Sharp GF-6060H - Alignment Instruction

GENERAL ALIGNMENT INSTRUCTION
Should it become necessary at any time to check the alignment of this receiver, proceed as follows;
1. Set the volume control (VR101-C) to maximum. 3. Use a non-metallic alignment tool.
2. Attenuate the signals from the generator enough to swing 4. Repeat adjustments to insure good results.
