How to use

Extend the external antenna for improved reception when tuning FM, MW or SW. Use the tuner dial to locate radio stations and adjust volume with the rotary control. To play cassette tapes, insert a cassette into the deck and press play; to play MP3 files insert a USB stick or SD card into the appropriate slot and select the corresponding source. To record, choose the source (radio, tape, USB/SD or microphone) and initiate the record function following the device's front‑panel controls. When using battery power, monitor remaining battery life and switch to AC when convenient to avoid interrupted recordings.

Usage recommendations

For best radio reception, position the unit near a window and fully extend the external antenna. Use good‑quality D‑cell alkaline batteries for longer portable operation, and regularly back up archived cassette recordings to USB or SD to preserve fragile tape content.
