No clinical data provided. Device performance is supported by bench testing and compliance with ANSI S3.2-1987 standards for frequency response and technical specifications.

Technological Characteristics

FM at-the-ear auditory trainer; Adaptive Compression; True FM Override; volume control, mode switch, and audiological output/tone controls. Power: 675 hearing aid battery. Technical specifications comply with ANSI S3.2-1987. Form factor: BTE (Behind-The-Ear).

Indications for Use

Indicated for individuals with slight to profound hearing loss, including high frequency, gradually sloping, reverse slope, and flat configurations, and those with low tolerance to loudness. Specifically suited for students of middle school age and older with moderate to profound hearing loss.

Regulatory Classification

Identification

A group hearing aid or group auditory trainer is a hearing aid that is intended for use in communicating simultaneously with one or more listeners having hearing impairment. The device is used with an associated transmitter microphone. It may be either monaural or binaural, and it provides coupling to the ear through either earphones or earmolds. The generic type of device includes three types of applications: hardwire systems, inductance loop systems, and wireless systems.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

Dear Mr. Scheller:

We have reviewed your Section 510%) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Ouality System Regulation (OS) for Medical Devices: General regulation (2) CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register.

| 5. Profound | √ | 5. Other: | | |

B. Specific Indications (only if appropriate.):

(Most psychoacoustic indications such as improved speech intelligibility in background noise, must be supported by clinical data.)

The Telex Select 1-40 BTE FM System is best suited for students of middle school age and older who have a moderate to profound hearing loss. It may be appealing to older students that have rejected FM amplification because of the stigma associated with body-worn auditory trainers.
