1. The telephone can be combined with a programmed exchange and a coupler to form an independent communication system.
2. Directly connects to telecommunication networks.
3. After forming the communication system, each telephone is an independent workstation, and a failure in one does not affect the operation of the entire system.
4. After the communication system is assembled, the product features automatic gain, ensuring voice volume remains consistent regardless of distance or the number of telephones.
5. The internal circuit of the telephone uses a universal double-sided integrated circuit, offering advantages such as accurate dialing, clear conversation, and stable operation.
6. Stainless steel housing, high mechanical strength, and strong impact resistance.
7. The surface of the button is smooth with no indentation; made of stainless steel, it is resistant to acids and alkalis, and has strong chemical corrosion resistance, making it suitable for cleaning with various detergents.
8. Hands-free design to prevent cross-contamination; the phone's built-in circuitry has strong anti-interference capabilities, ensuring stable and clear call quality.
