SN-568/SN-588 ultra-long-distance cordless telephone functions and features: (machine to prevail in kind, practical, ultra-high-power, long distance,)

1 ultra-high frequency, and the use of one hundred thousand bi-directional password, using safe and reliable, can not hit false alarm bell.
2 ultra-high-power transmitting tubes, transmitter power up to 10W, greatly extend the communication distance. Open to 48-128 km (theoretical distance).
3. Using PLL frequency synthesizer technology greatly improves the stability of work machine. CAD design, elaborate, layers of detection, performance is highly stable and reliable.
4 strong anti-interference: the host and sub-machine built-in 8-bit code switch, the frequency can be set to 256, a case of interference the user can set their own frequency. Alert the user to be selected according to local conditions suitable frequency. Or they may cause interference with other communications because of other distances. (Such as local radio interference with other wireless devices)
5. AT-588 AC power supply input voltage range from 85V-265V can be stable output DC15V, particularly suitable for voltage fluctuations calendar harm the rural areas.
6 Caller ID: When the vice unit has an external telephone calls to ordinary phone display, you can with this body into a DTMF / FSK dual system compatible with automatic identification of caller ID phone.
7 frequency settings: host and slave built-12345678-Octet Coded switch to change the code switch up and down position to change the frequency, the frequency will change the primary and secondary machine while the corresponding number of coded switch set on or set, the special Note must ensure that primary and secondary machine 12345678 eight coding switches exactly the same position, or frequency of the main and sub machine inconsistency will lead to the main sub-machine can not call each other, and the other machine can not find main and call each other, they should first check the location of the main and sub machine code switch are the same.
8 This product is the best choice for point to point communication; coupled with car antenna for mobile communications also enable you to have an unexpected effect.
