RADIO – CIRCUIT OPERATION

Side Screen Antenna

The antenna is printed into the rear side screen. For NAS and Japan, the element is fitted in both rear side screens. This is referred to as a diversity antenna system. Other markets have a single element in the right hand screen only. Diversity reception means that as vehicle movement results in loss of signal due to reflections from buildings (known as multipath distortion), the radio will switch to the antenna receiving the strongest signal. This results in less interference and better stereo performance.

Antenna Amplifier

Antenna amplifiers are in the LH and RH side of the luggage compartment behind trim panel.The FM and AM amplifier would be located on the right hand side, and the FM only amplifier is located on the left hand side.

Speakers

Trim level 1/2 - The low/midline radio is equipped with 6, 8 or 10 speakers fitted in the doors. The midrange speakers (K200, K201, K211, K212) are filtered by capacitors in the wires (K239, K240, K247, K248) and the tweeter speakers (K197, K198) filter the signals by built-in capacitors. Trim level 3 - the high line is equipped with 10 speakers like the trim level 1/2, but they all receive power and ground via 4 additional speaker amplifiers. The signals for the tweeter speakers (K197, K198) are filtered by their internal capacitors, similar to the mid/low line tweeters.
