Warning: Do not operate at continuous high voltage. At frequencies below 20 kHz, daily sound pressure exposures in excess of one hour at 105 dB may lead to hearing impairment.

Warning: A 30 ohm series resistor is recommended to assure stability of extended range ampliers and preclude hazard of burnout.
