Before you start using this device, please read these instructions carefully to learn about features and functionalities. NOTE Your device may not look exactly as illustrated. We reserve the right to make any changes considered necessary. Intended use The device is intended to transmit audio from the built-in microphones to supported hearing aids to improve speech understanding in noisy situa- tions. The device can also receive audio from multiple sources (analog and digital) and transmit the audio wirelessly to the supported hearing aids. Further, the device can be used as a remote control to adjust the supported hearing aids to different listening situations. 4 Warnings Strangulation hazard when neck loop or charging cable gets entangled in moving mechanical parts of machines for example. - Use only the delivered breakaway neck loop. It will automatically detach when entangled. - Do not use neck loop or charging cable for children under the age of twelve. Your device should be stored and transported within the temperature of -20 °C to +55 °C (-4 °F to 131 °F) and humidity ranges of 10-95 % RH. Your device is designed to operate at temperatures during charging of +0 °C to +40 °C (32 °F to 104 °F) and during use at temperatures of -10 °C to +40 °C (14 °F to 104 °F), at humidity ranges of 10-95 % and under at- mospheric pressures of 750-1060 mBar. Risk of injury or electrical shock caused by damaged devices. Do not use obviously damaged devices and return them to point of sale. Never dry your devices in the micro-wave or oven. Keep the device protected from dust or external particles. We recommend using a 5 V up to 500 mA micro USB adaptor. Do not leave the device unattended while charging. 5 Do not dispose of this device into fire or a hot oven and do not crush or cut the device, as this can result in an explosion. Do not use or wear the device in mines or other areas with explosive gases, including while refuelling a vehicle. Do not leave the device in an extremely high temperature surrounding environment, as this can result in an explosion or the leakage of flamma- ble liquid or gas. Do not subject the device to extremely low air pressure, as this can result in an explosion or the leakage of flammable liquid or gas. When the device is connected via micro USB cable to external mains-op- erated equipment such as a charger, PC, audio source or similar, this equipment must comply with IEC 60950-1, IEC 62368-1, IEC 60601-1 or equivalent safety standards. Only the accessories and cable that are included in the sales box must be used. Using cables other than those specified or provided may result in increased electromagnetic emissions or decreased electromagnetic im- munity of this equipment and result in improper operation.

Pairing the device Sound Assist must be paired to your hearing aids before you pair with other devices. Pairing to your hearing aids: 1.Make sure that Sound Assist is turned off. 2.Restart your hearing aids. The hearing aids will then be in pairing mode for 3 minutes. 3.Press the volume up button (+) and the power/mode button (1.6) si- multaneously for 3 seconds until the in-use light indicators (1.5) are glowing blue. 4. Make sure that the Sound Assist and your hearing aids are within 1 m range of each other. 5.The pairing sequence will start automatically. 6. The in-use light indicators (1.5) will briefly flash green, when the pairing is successfully completed. The Sound Assist can only be paired to one set of hearing aids. To pair a new set of hearing aids, you must perform the same steps and the new pairing will overwrite the existing one. Pairing to your smartphone or other device: 1.Turn off your Sound Assist. 8 2.Activate Bluetooth on your smartphone/device. 3.Press the volume up button (+) and the power/mode button (1.6) si- multaneously for 3 seconds until the in-use light indicators (1.5) are glowing blue. 4. Make sure that Sound Assist and your phone/device are within 1 metre range of each other. 5.Go to the Bluetooth menu on your smartphone/device and pair by se- lecting Sound Assist from the list of available devices. 6. The in-use light indicators (1.5) will briefly flash green, when the pairing is successfully completed. Sound Assist can be paired with up to 8 Bluetooth devices and actively con- nected to 1 Bluetooth device. To reset hearing aid and phone/device pairings: 1.Turn off your Sound Assist. 2.Press the volume down button (-) and the power/mode button (1.6) si- multaneously for 5 seconds. 3.When the pairing list is resetting, the in-use indicators (1.5) will start flashing yellow. 4. When the reset is completed, the Sound Assist will turn off. 9 Range FunctionMax ranges Remote microphone8 m from hearing aid to the device Bluetooth streaming10-15 m from Bluetooth device to the device Partner microphone20 cm from speaker to the device Tabletop microphone1.5 m from speaker to the device Turning Sound Assist on and off To turn on and off, press and ho…

POWER SUPPLY (*): Vnominal: 5V Type of Power Supply: External Power supply / Battery ANTENNA (*): Type of Antenna: Internal IFA (muxed) Maximum Declared Antenna Gain: 1.3dBi TEST FREQUENCIES (*): Low Channel: 2402 MHz Middle Channel: 2441 MHz High Channel: 2480 MHz CONDUCTED MEASUREMENTS: The equipment under test was set up in a shielded room and it is connected to the TS8997 using a low loss RF cable. The reading of the spectrum analyser is corrected taking into account the cable loss. RADIATED MEASUREMENTS: All radiated tests were performed in a semi-anechoic chamber. The measurement antenna (Bilog antenna for the range between 30 MHz to 1000 MHz and 1 GHz-17 GHz Double ridge horn antenna) is situated at a distance of 3 m and at a distance of 1.5 m for the frequency range 17 GHz-26 GHz (17 GHz-40 GHz horn antenna). For radiated emissions in the range 17 GHz-26 GHz that is performed at a distance closer than the specified distance, an inverse proportionality factor of 20 dB per decade is used to normalize the measured data for determining compliance. The equipment under test was set up on a non-conductive platform above the ground plane and the situation and orientation was varied to find the maximum radiated emission. It was also rotated 360º and the antenna height (Bilog antenna and Double ridge horn antenna) was varied from 1 to 4 meters to find the maximum radiated emission. Measurements were made in both horizontal and vertical planes of polarization. A resolution bandwidth/video bandwidth of 100 kHz / 300 kHz was used for frequencies below 1 GHz and 1 MHz / 3 MHz for frequencies above 1 GHz. DEKRA Testing and Certification, S.A.U.
