Q620B is a dual-line dual-mode multifunctional business phone that cleverly combines landline and mobile phone (via Bluetooth technology) into a practical dual-mode desktop phone. It allows mobile calls to become desktop calls with clear hands-free function. It also supports three-way calling, phone call while charging, placing the phone in a good signal area when the signal is unstable, and reduces the impact of mobile radiation on the body.
The Q620B is a high‑end Bluetooth hands‑free device that can connect to a mobile phone via a single Bluetooth link. It supports hands‑free, headset, A2DP and AVRCP profiles, offering call handling, voice prompts and mute functions while reducing phone radiation exposure.
The manual describes how to pair the phone within a 5‑8 m range, operate call functions such as call waiting, hold, mute, and message notifications, and details the power requirements (9 V 300 mA) and indicator LEDs for status monitoring. This manual is written in Chinese.
