A.C. Marias - One Of Our Girls Has Gone Missing

In 1989, it's a Mute 12 product, MUTE 105, with unique features.

This product is a great one. There's no special way to use it, just handle it gently. Keep it in a dry and clean place to avoid damage. If there's any problem, don't try to fix it by yourself, and contact the customer service instead.
