Operation Instructions Connect the antenna cable to the left F Female and the battery pack cable to the right F Female. Ensure any external amplifier is disconnected from the antenna. Adjust the antenna by monitoring the meter's reading. Move the antenna until obtaining the highest possible reading. If the meter is full scale, turn the level control knob clockwise to reduce the reading to around 5. Once adjusted, disconnect the finder and reconnect any previously removed amplifier. Important Note: If your antenna includes an internal amplifier (e.g., 01MM-SQ01), it should be powered externally via a DC power inserter positioned between the finder and the antenna.
