The E-Scope provides exceptional sound quality for general medical use. Amplification can be increased or decreased. The maximum amplification is about 30 times that of a normal acoustic stethoscope. The E-Scope is one-hand controlled. When activated the E-Scope will stay on for 1.5 to 2 minutes, then automatically turn off. Upon restart, it returns to the prior volume setting. The default is in the heart sound mode, that is, when turned ON, it will turn on in the heart sound mode. The E-Scope has 64 gain positions for fine tuning the volume to the user’s specific requirements. One the side of the E-Scope is a “Sounds Output” port that allows the user to connect to a variety of accessories such as (1) headphones or stethophones for a second listener, (2) a PC or laptop computer, (3) speakers, (4) hearing aid accessories, etc.An off-the-shelf AAA battery powers the E-Scope for approximately 4 months depending upon usage. This assumes that the E-Scope is used 30 times per day, 6 days per week. Accessories included are (1) mushroom and hard plastic ear tips, (2) a stamped metal pediatric diaphragm, (3) plastic adult, pediatric and infant bells.
