WARNING: Do not turn the volume up too high on the EAR3H. Please exercise extreme caution when
doing so. It has the potential to damage helmet speakers, earphones, headphones, etc., should they
not be rated for a higher audio input. Use the volume amplification slowly and proceed with caution
to avoid over boosting your helmet speakers, earphones, headphones, etc., but most importantly, to
avoid permanently damaging your hearing.
