This document provides user instructions for the Advance 52 series A52-FS model hearing aids, which are Receiver-in-canal (RIC) or Receiver-in-the-ear (RITE) devices.
Function Description:
The Advance 52 series A52-FS hearing aids are air conduction amplification devices designed for everyday listening environments. They are intended for individuals with hearing loss ranging from minimal (10 dB HL) to severe-to-profound (100 dB HL) across all hearing loss configurations. These devices are programmed by licensed hearing care professionals, including audiologists, hearing aid specialists, and otolaryngologists.
A key feature is the optional Zen program, which provides a relaxing sound background (music/noise source) for adults who desire such a background in quiet environments. The hearing aids can be equipped with an Audibility Extender feature, which can be activated by a hearing care professional depending on the user's hearing loss.
The hearing aids offer various listening programs to adapt to different sound environments:
- Universal: For everyday use.
- Quiet: A special program for listening in quiet environments.
- Transport: For listening in situations with noise from cars, trains, etc.
- Urban: For listening in situations with changing sound levels (e.g., supermarkets, noisy workplaces).
- Party: For listening in situations with many people talking simultaneously.
- Music: Specifically designed for listening to music.
- T (Telecoil): Allows listening directly through the hearing aid's telecoil to sound without background noise (requires a teleloop system).
- M+T (Microphone + Telecoil): A combination program where the user listens to the sound source via the telecoil but can also hear other sounds through the microphone.
- Zen: Plays musical tones or noise for a relaxing sound background.
- Phone: Designed for listening to phone conversations.
The hearing aids also include SmartToggle programs:
- Zen+: Similar to Zen but offers different types of tones or noise.
- Phone+: Allows listening to the phone while avoiding surrounding sounds, with one hearing aid transmitting the conversation to the other for binaural listening.
The push button on the hearing aid can be configured in several ways:
- Dedicated program button: A short tap changes programs. A push and hold (optional) accesses and exits SmartToggle programs, with subsequent short taps changing Zen styles.
- Dedicated sound adjustment button: A tap on the right hearing aid increases audibility/volume, while a tap on the left hearing aid decreases volume/increases comfort. A long push on either hearing aid (optional) mutes and unmutes the sound.
- Combined program and sound adjustment button: A tap on the right hearing aid increases audibility/volume, and a tap on the left hearing aid decreases volume/increases comfort. A long push on either hearing aid changes programs. For single hearing aid users, a short tap changes programs, and a long tap accesses SmartToggle programs.
