 System overview

Your Tinearity G1 device is designed to relief and treat your symptoms associated with tinnitus by the use of white noise. The white noise is by the sound generator converted into vibrations that are transmitted via the adapter through the skull to the inner ear. This method works independently of the ear canal and the middle ear and facilitates the treatment to be performed without obstructing your normal hearing canal. Thus, your Tinearity G1 device can be used at all times during the day, during work, during activities as well as during sleep.

CAUTION
The sound generator shall never be cleaned or submerged in or under water or other liquids.

Tinearity G1 description

Device overviewDUEARITY Tinearity G1 Treat Tinnitus Using White Noise
02Tinearity™ G1 comprises three components:

  1. the sound generator,
  2. adapters and
  3. a charger (including a USB cable for connection to a power supply).

The sound generator is attached to the skin behind the ear by means of the adapter. The sound generator works within the frequency span of 1kHz‐10Khz with a maximum output level of 48dB HL. This device is intended for use during eight (8) hours a day when set at the maximum output level. The sound generator is supplied in pairs, with the intention to be used at both sides of the head. The adapter is a disposable device that serves as a mechanical connector between the sound generator and the user. The adapter is made up of a plastic holder that are compatible with the sound generator and a medical grade tape to be attached to the user’s skin. The adapter is a single use device and is designed to be removed daily after each treatment. The sound generator uses a re‐chargeable battery as a power source which is charged with the charger. The charger consists of a charger plate designed for two sound generators to be charged simultaneously and a separate USB cable with a USB‐C port for connection to the wall socket. The Tinearity G1 sound generator and adapter can be used at all time during the day, during sleep as well as during work and spare time.
CAUTION : The sound generator shall never be cleaned or submerged in or under water or other liquids.

Preparation before every use

 Skin hygiene

The skin behind the ear must be clean, dry and free from hair. If the hairless area is not large enough, adjust the hairline with a razor.
Clean the skin with mild soap and let it dry completely before you apply the adapter.

Sound generator and Adapter

Check the sound generator and the adapter visually before use, for any damage.
WARNING: If covers are damaged or any parts are loose, do not use the device.
Clean the sound generator according to section 11.

Charger

Place the device on a flat surface.
WARNING: Check the cable and connections for pinching or damage. Pets and pests may damage the insulation of the cables. Do not use damaged cables.

 Operating instructions user

Applying the adapter

  1.  Locate the area for application of the adapter behind the ear. To maximize the performance of your treatment make sure that the adapter is placed at the mastoid bone and orientated as illustrated in below figure. Make sure that the area is free from hair. Note: the adapter has a single curvature designed to be follow the curvature behind the ear, therefore correct rotation on the application of adapter is advised to ensure a good adhesion.
    Correct application, the soft part is applied closest to the ear. In‐correct application, rotate the adapter 180 degrees relative your skull. In‐correct application, rotate the adapter 90 degrees relative your skull.
    Note: Transfer of sound/noise through Bone conduction is most effective if the adapter is attached to the skin where the tissue thickness is minimized.

  2.  Hold the adapter in the wings.
