How do I maximize my scope's acoustic performance?

To maximize performance of your ADC scope, you want to optimize the seal from the scope's chestpiece to your ears. Any leakage or obstruction will impede performance. First, align the binaurals properly so that the eartips point towards the bridge of your nose. On PROSCOPE series scopes and the ADSCOPE 641, you will need to adjust the binaurals to align the eartips correctly. On ADSCOPE series scopes, the binaurals are pre-angled 15° forward for a snug fit. But, you must make sure to position them correctly - eartips FORWARD. Next, adjust the binaural tension. Too loose and acoustic transmission will suffer. Too tight and the scope will not be comfortable. To reduce the tension, grip the binaurals firmly using both hands with fingers at the center of the "Y" in the tubing, thumbs at each side with the tubing branches out. Flex binaurals gradually until the desired tension is obtained. To increase the tension, grip the binaurals in the hand and squeeze the binaural tubes together gradually. Please note that excessive adjustment of the spring tension could weaken the spring. Select the eartips that are most comfortable and best seal the aural canal. ADC scopes come with at least two pairs of eartips; many are equipped with three pairs. Finally, make sure that you maintain your scope in good working condition. Obstructions from dust or dirt in the binaurals will impede performance, while tubing cracks will permit acoustic leakage.
