Installation

Unpack and inspect contents. Place on stable surface near your audio system.

  1. Connect antennas: Attach FM antenna to 300 ohm terminals; AM loop antenna to AM terminals.
  2. Connect to amplifier: Use RCA cables from AUDIO OUT to amplifier AUX/TUNER inputs.
  3. Connect power cord: Plug into AC outlet.
  4. Position antennas: FM antenna should be extended vertically; AM loop oriented for best reception.

WARNING! Ensure proper ventilation; do not block ventilation openings. Use stable surface to prevent tipping.
