The telephone can form an independent communication system with the program-controlled switch and coupler.
can directly connect to the telecommunication network
After the call system is formed, each phone is an independent workstation, and one of the failures does not affect the entire system.
After the call system is formed, the product has an automatic gain function, and the size of the voice does not vary with the length of the distance or the number of the phone.
Amplifier speaker sound size can be adjusted freely
The patented design of the phone case is waterproof, dustproof, no need for waterproof cover, beautiful and practical.
The circuit inside the telephone adopts the international universal double-sided integrated circuit, which has precise number and call.
Clear, stable work and other advantages.
