If your television/sound source has an optical output available, use the
optical cable to connect it to the driver’s Optical/Digital In (3 in the
diagram above). The Line Out jack (5 in the diagram above) is driven
only from the optical cable input. The HLD3 accepts PCM digital audio.

Metal loss occurs when a large amount of metal in the surrounding
area affects your hearing loop’s higher audio tones. To adjust for this,
turn the HF Comp adjuster (4 in the diagram above) clockwise until the
higher pitched sounds are at a suitable strength.
