This manual explains how to install the BBK telephone system, including connecting the base unit, power transformer (BBG‑T‑07), and optional ADSL voice separator. It also covers charging the cordless handset, pairing (coding) procedures, and how to adjust display brightness, date, time, and ringtone settings.
Additional sections describe how to make and receive calls with both the base and handset, use features such as call‑waiting, do‑not‑disturb, and night‑light, and troubleshoot common problems like no ringing, poor audio, or battery issues. Technical specifications are listed at the end of the document. This manual is written in Chinese.
