The Sampo CT‑W12L is a cordless telephone system consisting of a base unit (母机) and one or more handsets (子机). It is powered by a DC 9 V / 200 mA adapter and the handset uses a rechargeable battery. The device supports both DTMF and FSK signaling and can store up to 70 incoming call records.
The manual is organized into sections covering installation, pairing of handset and base, power connection, time and date setting, incoming‑call display, normal operation, battery charging, and troubleshooting. Each section provides step‑by‑step instructions and safety notes to help users set up and maintain the telephone. This manual is written in Chinese.
