| 摘要 |
The invention is a theft deterrent arrangement for a motor vehicle audio apparatus (10) where the audio apparatus (10) is enabled when an opto-electronic circuit (7,11,13) is closed by a security bezel (1) removably seated in a recess (3) in a front face (2) of the audio apparatus (10). The security bezel (1) has a light pipe (17), so that when the security bezel (1) is seated in the recess (3), the light pipe (17) provides an optical path (32) between a light detector (13) and an emitter (11) fixedly mounted in the recess (3), thereby closing the opto-electronic circuit (7,11,13) and enabling the audio apparatus (10). <IMAGE> |
