DESCRIPTION

If there is a short in this circuit, the radio receiver detects it and stops output to the speakers.
Thus sound cannot be heard from the speakers even if there is no malfunction in the radio receiver or speakers.
If a short is detected in the speaker circuit, no sound can be heard from the speakers.
