1. The phone can form an independent communication system with a programmable exchange.

2. Directly connects to the telecommunications network.

3. Once the call system is assembled, each phone is an independent workstation, and a failure in one does not affect the entire system's operation.

4. Built-in amplifier, supports external speakers and sirens; automatically connects upon incoming calls, disconnects during power outages for added safety; once the communication system is set up, the product features automatic gain, ensuring voice volume remains consistent regardless of distance or number of phones.

5. The internal circuit of the telephone uses a DSPG digital chip, offering advantages such as accurate dialing, clear conversation, and stable operation.

6. Carbon steel surface electrostatic powder coating, high mechanical strength, and strong impact resistance.
