The Vista completely in the canal (CIC) is a small instrument designed to fit competely in the ear canal. The volume control is a standard screw-set control and uses a #10A or 5A battery. The CIC fit reduces residual ear canal volume and results in the need for less gain, decreased chance of feedback, improvement of high frequency gain, decreased occlusion effect, and lesser self-masking. The CIC's circuits are assembled into a variety of different configurations including Class D, K-amp, and RGA Class A. Assembled from standard components which are widely utilized by other hearing aid manufacturers. Technical specifications comply with S3.22-1987 ANSI Specifications. Dispenser controlled Volume Control. The frequency response of this product is dictated by the individual audiogram from each client. Standard hearing aid battery.
