Handling Precautions
• Never connect or disconnect plugs to/from the input/output terminals on the PHA-1 when the external device that drives speakers is powered. Doing so
can cause noises and damage the speakers.
• Avoid applying excessive force to the knobs, tact switches, DC jack, and phone jacks on the PHA-1.
• Do not push or press the display on the PHA-1.
• If the unit malfunctions or behaves erratically, cease operation at once and contact your local dealer or Free The Tone directly.
