Magnet telephone HDX-5A

summary

This phone is mainly used for wired communication in the wild (or indoors). it

Simultaneously equipped with: magnet, common electric, automatic (pulse, dual tone multi frequency), magnet dual tone multi frequency

Five working modes.

The magnetic part of the phone is replaced by an electronic bell generator and an electronic bell, respectively

Hand cranked generators and mechanical electromagnetic bells; The receiving and sending bell streams have display functions; The electronic ringing tone of the phone does not vary with the length of the external line.

The automatic part of the telephone (including shared power) is suitable for automatic telephone exchange systems with a feeding voltage of 24-60V and a current of 18-80mA. When using pulse/dual tone multi frequency signal transmission, it can store 32 digits and is equipped with over signal redial, R key, hang up key (640ms), pause key (2.2S), and P → T conversion function.

Phone magnet dual tone multi frequency method can output dual tone multi frequency without the need for switch feeding

Frequency signal, combined with dedicated 20 line switch for automatic telephone exchange without power supply

The system solves the problem of short direct distance between the telephone and the switch in automatic (shared power) mode.

The phone can be activated through a tone up switch when using magnetic or magnetic dual tone multi frequency mode

The communication distance reaches 38 kilometers.

The overall performance of the machine is stable and reliable, with clear voice and good electromagnetic compatibility.

The phone has a reasonable structure, light weight, and is easy to carry; The whole machine has good waterproofing

Moisture resistance, vibration resistance, and drop resistance.

This phone has strong applicability and can be used simultaneously in magnet, automatic (including shared power), and dedicated communication

Switching to internal use, with good mobility and full functionality, it is currently the most technologically advanced full system

Type electronic telephone.
