!
Do not operate your device at high volume levels when using the EAR3H Amplifier. Hearing experts advise
against continuous exposure to high volume levels. If you experience ringing in your ears, discontinue using
the EAR3H immediately.
Do not turn the volume up too high on the EAR3H. This amp has the potential to damage helmet speakers,
earphones, headphones, etc., should they not be rated for a higher audio input. Use the volume amplification
carefully by increasing the volume slowly. Proceed with caution to avoid over boosting your helmet speakers,
earphones, headphones, etc., but most importantly, to avoid permanently damaging your hearing.
