Rhythm-K1 The device is auditory electronic pocket.

The device is intended for correcting medium to severe hearing loss (45-95dB). The device is used in the patient's pocket during operation.

The power of the device is taken from the element 316 (type AA) with a nominal voltage of 1.5 V.

The device has smooth non-operative regulators:

- the control of the limitation of the output sound pressure level "P"

- low-frequency tone control "N-H"

- High-frequency tone control "N-L"

When selecting the device, depending on the individual hearing loss, the doctor puts the necessary position of nonoperative regulators.

It is not recommended to use these regulators independently.

The kit includes:

-machine Rhythm K-1

-cord

-Telephone VTU

Ear inserts 1C, 2C, 4C, 1K

-case
