2, Display: Support Caller ID or IP address. (Optional)

3, seismic: mosaic hook design, especially for ships, marine platforms, locomotives, which are vibration and a typhoon of places

4, button: SUS304 stainless steel button, wear, corrosion resistance, anti-aging, anti-violence, destruction.

5, handle: Germany imported materials, integrated structure, good sealing, withstand twisting does not break the continuity of percussion pull deformation resistance, light resistance, high temperature fire performance does not burst at minus 40 degrees away product quality.... far better than PC and handset ABS material.

6, wire: using military-grade standard Teflon wire, acid and alkali resistance, high temperature, anti-aging, no fire.

7, waterproof plastic: The international brand waterproof glue, high viscosity, high temperature, high pressure, waterproof life of more than 10 years.

8, the handset is a military grade, industrial-grade custom dedicated headset, keyboard, buzzer, circuit boards, multi-layer waterproof shell with all accessories, dust-proof structure. Has three waterproof, dustproof functions, the whole level to the national standard GB4028-93 IP66

9, good phone stability, strong anti-jamming capability, in line with the national standard GB / T 15279-94

10, with the speakerphone function: When the ambient noise over 90 db, ordinary telephone ringing often can not get the staff heard the bell, leading to production scheduling instruction can not be communicated in a timely manner, resulting in economic losses.

The main technical parameters:

1, suitable for a variety of feed voltage PBX switches and dispatch and scheduling of the switching system 33-60V

2, temperature: -35 ℃ ~ 75 ℃ Relative Humidity: 10% to 95% Atmospheric pressure: 86 ~ 106 Kpa ambient noise: ≤60dB (A)

3. Ringing level: ≥120dB

4, when the user is 3KM line signal level standard frequency: low frequency group: 697-941Hz high frequency group: 1209-1477Hz

Frequency Offset: less than ± 1.5% of the combined signal of high-frequency level difference: 2 ± 1dB

Total harmonic intermodulation distortion caused by the at least 20dB lower than the basic level

5, call transfer indicators: SLR≤12, RLR≤-1, STMR≥10, output impedance: 600Ω
