Automatic dial-up telephone function parameters
2. Equipped with a keyboard lock, it supports emergency call setting. Within 3 seconds after lifting the microphone, only the toll-free service numbers such as 1 10, 120, 1 19 are allowed to be dialed manually.
3. If you don't put down the receiver after the phone call, but the person has left, or the phone is turned on because the receiver has dropped, the machine will automatically hang up after 10 seconds to prevent the line from being busy.
4. After power failure, the setting information will not be lost, but it will be permanently saved.
5, built-in interface, access to the telephone line is not exposed, to prevent disconnection or private phone calls.
6, Full Metal Jacket, engineering plastic telephone handle, metal protective tube, the whole machine is resistant to falling, dragging and prying, durable, and has a strong ability to prevent malicious attacks.
7. If anyone is found to have vandalized through monitoring, you can call back immediately, and the phone will be automatically connected, and the speaker will be started to shout at the scene, which will play a deterrent role.
8. The appearance of the whole machine is beautiful and fashionable, simple and smooth, eye-catching LOGO and warm, clear and easy-to-understand operation tips, which effectively enhance the image.
9. Reasonable structure, modular design and convenient maintenance.
