Features:
1. The volume of sound increases 2-3 times.
The highest volume reaches 105-110dB in order to be applied to noisy environment. (When sound increases 6dB, ear pressure adds to two times)
2. The sound spreading increases 4 times. (>96dB, 12m; >102-105dB, 9m)
3. The sight distance of brightness reaches 2000m.
4. Reliable and stable functions.
Because the CPU line with software is used, the technological process and environment have little effect on the items of the apparatus, and reliability and stability are increased greatly.
5. High precision.
The encrypted methods adopt the input routine of software in the wave of the line, sound, brightness and time.
6. Economic product.
No consumption in 3 years.
7. Convenience.
Equipped with intelligent aluminum alloy charging box, provided with digital display of the current, the indicator light of charging, and the protection of the short circuit and self-cut of charging. Convenience for storing.
