2.1 Ezairo 7160 SL Hybrid Module
Ezairo 7160 SL is an open-programmable DSP-based hybrid module specifically designed for wireless enabled,
high-performance hearing aids. The Ezairo 7160 SL hybrid is comprised of: the Ezairo 7100SL System-on-Chip
(SoC) audiology processor; RSL10, the industry's lowest power Bluetooth® 5 radio SoC; EA2M, a 2 Mb EEPROM;
and all necessary passive components for operating the sub-system and interfacing with hearing aid transducers.

  • Page 7: Initial Setup

    Sound Designer Software works with any of the programming boxes listed above, but before using a wireless programmer or any other wireless feature, Ezairo 7160 SL must first be configured for wireless operation using a wired programming box. In addition, you must ensure that the Windows drivers provided by the manufacturer have been installed prior to using Sound Designer Software.
  • Page 8 Semiconductor > Sound Designer > Sound Designer. Select the appropriate programming box installation procedure from the following list: If you are using a DSP3 (from manufacturer ON Semiconductor), install the DSP3 Programmer driver version 2.1.71 (included in redistribution/DSP3). If you are using a HI-PRO (from manufacturer Otometrics), install the latest HI-PRO driver (currently version 4.02) from Otometrics®;...
