Specifications: Compass with attenuation control function easily locate satellite signal. Corrosion-resistant connectors. In-line IF signal strength meter. Excellent sensitivity. Great for remote satellite antennas. Elegant exterior and convenient to carry. Operation: 1. Connect the antenna cable to the left F Female and the battery pack cable to the right F Female. Remove any external amplifier that may be connected to the antenna. 2. Adjust the antenna to the best position by watching the meter's reading. Higher up the scale gives a better signal. If the finder's reading becomes full scale, adjust the level control knob to reduce the reading to around 5 (turning the knob clockwise will decrease the reading), continue to move the antenna until you have the highest possible meter reading. 3. Remove the finder and replace any amplifier that was disconnected. 4. If your antenna has an internal amplifier, (eg: 01MM-SQ01), it should be powered by an external power supply via a DC power inserter. Make sure the power inserter is positioned between the finder and the antenna.
