The BBK telephone system includes a base (座机) and one or more sub‑phones (子机). The manual explains how to install the base, connect the power transformer (BBG‑T‑07), set up the charging dock, and configure basic features such as date, time, and ringtone selection.
It also covers everyday use – making and receiving calls, three‑way calling, dialing shortcuts, and how to adjust LCD brightness, volume, and alarm settings. A troubleshooting section lists common problems like no ringing, noise, and battery issues, with step‑by‑step remedies. This manual is written in Chinese.
