Features: Equipped with excellent sensitivity and accuracy, helps you find the best position for DVB-T NET installation. Designed with a compass for easier and faster adjustment. With buzzer and attenuation control function, simple and user-friendly operation. Feedback figures show the signal strength intuitively. Mini-size and light weight, truly portable and easy to carry. Usage: 1. Connect the NET cable to the left F-female and the battery cable to the right F-female. Remove an external amplifier* that may be connected to the NET. 2. Adjust the NET to the best position by looking at the meter reading. The higher the scale, the better the signal. If the seeker's reading becomes full scale, adjust the level adjustment knob to reduce the reading to about 5 (turning clockwise reduces the reading), continue to move the NET until you have the highest possible meter reading. 3. Remove the seeker and replace any amplifier that has been disconnected. Important Note: -If your NET has an internal amplifier (for example: 01mm-SQ01), it must be powered by an external power supply via a DC power injector. Make sure the power injector is placed between the seeker and the NET.
