Stallation and operating
1 Before use the amplifier, test input level whether at the range of input level. You should adjust input level into it.
2 Output level can’t be too high. Just keep every TV set level at 60~75 dBμV. Turning ATT knob to adjust output level.
3 When in thunder, to avoid lightning strike, you’d better turn off power supply. The amplifier used indoor only and avoid be affected with damp or high temperature.
4 Keep power supply voltage at common range. Too low voltage will cause figure quality bad.
