VLACIC'S ON/OFF AND ADJUSTABLE SOUND VALVE

摘要

Vlacic's ON/OFF and adjustable sound valve is snapped in through the predrilled hole in the lower right corner of the ear muff. It provides ON/OFF and the adjustable feature for the opening and closing the valve. ON/OFF feature means that when the button is pressed down the sound path through the valve from the exterior to the interior of the ear muff is opened, or when the valve button is not pressed down sound path through the valve from the exterior to the interior of the ear muff is closed. Adjustabl e feature means that when the valve button is turned clockwise the sound path size through t he valve from the exterior to the interior of the ear muff is adjusted to a greater size, or when the valve button is turned counter clockwise the sound path size through the valve fro m the exterior to the interior of the car muff is adjusted to a smaller size. (This is the explanation for right side ear muff cup and the right side valv e. Left side ear muff cup and left side valve is opposite/mirror to this one).
