Abstract
The present invention provides a security system for audio equipment which allows users to easily release a security operation without having to remember any identification numbers or codes. The present invention provides a security system for audio equipment in which audio equipment in an inoperable condition is changed into an operable condition when data recorded on a recording medium during a playback condition matches identification data stored in a memory. Thus, the present invention allows users to easily release the security operation without compromising the level of security. Furthermore, the present invention prevents the audio equipment from being placed in an unlockable condition due to careless operation of users.
