The guide starts with unpacking the MCM277 and connecting the hardware: attach the FM wire antenna, MW loop antenna and AM antenna, connect left and right speaker wires, and plug the AC power cord. It also explains how to mount the base and install the wall‑mount kit if needed.
Next, it covers basic operation steps such as setting the 12/24‑hour clock, playing audio CDs (CDDA, CD‑R, CD‑RW, MP3/WMA‑CD), tuning FM/MW radio stations, and playing audio files from a USB flash drive (USB 1.1 or 2.0). Remote‑control functions and standby power‑off are also described. This manual is written in Chinese.
