AUDIO AND VISUAL SYSTEM(for Radio Receiver Type) Speaker Circuit

DESCRIPTION

The sound signals amplified by the radio receiver assembly are sent to the speakers from the radio receiver assembly via the speaker circuit.

If there is a short in a speaker circuit, the radio receiver assembly 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 assembly, telematics transceiver* or speakers.
