This is the operating instructions booklet for the Sony WM-GX788 Radio Cassette-Corder, a Walkman headphone stereo cassette player with a built-in radio and recording function. It explains how to power the unit with a dry battery, the supplied rechargeable battery NH-14WM (A) and the charging stand, or an optional AC-E15HG AC power adaptor.
The document describes playing a tape (including normal and double-speed playback, AMS track search, skip/reverse functions and A-B Repeat), recording from the built-in radio or the supplied microphone, and notes such as tape type restrictions, record-protect tabs and battery life figures. It also includes warnings on fire, shock and ventilation, plus the specifications table for the AC-E15HG adaptor.
