ReSound 2520-1002 Noahlink Wireless 2 User Guide

Intended Use

Congratulations on your Noahlink Wireless which will allow you to connect and fit wireless hearing instruments, without the use of an intermediate device, using easy plug-and-play functionality. Carefully read this user guide to fully benefit from the Noahlink Wireless.

Ask your local hearing instrument manufacturer if you have any questions.

Warning: Do not attempt to use Noahlink Wireless together with fitting software not specifically supporting the device. Noahlink Wireless can co- exist with other hearing instrument programming interfaces (e.g. Hi-PRO, NOAHlink) on the same PC.

Noahlink Wireless is intended to enable a hearing instrument fitter to wirelessly adjust the settings of wireless hearing instruments. The primary function of the Noahlink Wireless programming interface is to transfer information signals between a PC installed with fitting software and wireless hearing instruments.

For your safety, carefully read the chapter Safety & Compliance.

Description

1. Right side light indicator.
2. Left side light indicator.
3. USB-C port for power and communication with the fitting software.

Getting Started – Installation

Note: To ensure the best possible operation of the Noahlink Wireless always make sure it is placed out in the open with a clear line-ofsight between the Noahlink Wireless and the hearing instruments to be fitted.

Noahlink Wirelessis a USB plug-and-play programming interface enabling you to wirelessly fit hearing Instruments from licensed manufacturers. For a complete list of hearing instrument manufacturers who use Noahlink Wireless, visit www.himsa.com.

1. Before you connect Noahlink Wireless make sure that you have the approriate fitting software installed. The Noahlink Wireless driver is installed during fitting software installation.

2. After successful fitting software installation attach Noahlink Wireless to any USB port on the PC using the supplied USB cable. A 2-3 second solid green light indication will confirm that Noahlink Wireless is powered.
   

3. Performing a wireless fitting can sometimes be challenged dueto number of factors related to equipment setup, and thephysical layout of the fitting environment.

   • Place Noahlink Wireless on the table with a clear line-ofsight to the hearing instruments, which should be within a range of 10 feet (3 metres).
   • Avoid placing the Noahlink Wireless in a USB hub with other USB devices (e.g. Bluetooth dongle), as this candecrease the efficiency of the Noahlink Wireless.
   • When fitting hearing instruments inside a sound boothplace the Noahlink Wireless inside or close to the booth.
   • It is recommended not to use USB cables between the Noahlink Wireless and the PC exceeding a length of 10 feet (3 metres).

4. You are now ready to start fitting wireless hearing instruments.

Tips For Optimal Wireless Fitting

Let the battery breathe/oxygenize before inserting

When performing a wireless fitting, always use new batteries or newly recharged hearing instruments. The most common type of hearing instrument batteries are zinc-air. These types of batteries are activated by the oxygen in the air. By removing the small sticker from the battery, oxygen activates the battery. Because oxygen must pass through fine holes and a filter, the oxygen is absorbed slowly.

Therefore, it is important to wait 2 full minutes after removing the battery sticker and before inserting the battery and closing the battery door on the hearing instrument. If inserted prematurely, the battery may not absorb enough oxygen to properly power the hearing instrument.

Entering fitting mode

When connecting the hearing instruments to the fitting software make sure to always bring the hearing instruments into “Fitting mode” by rebooting them. For hearing instruments with removable battery this is done by opening and closing the battery door of the hearing instrument one time. For rechargable hearing instruments removins the instrument from the charging cradle will bring it into fitting mode.

By doing so it is possible for the fitting software to discover and communicate with the hearing instruments.

Note: If a hearing instrument is accidently put into flight mode where all wireless operation is disabled, just open and close the battery door again. After 10 seconds wireless operation is resumed. Keep the battery door closed for an additional 15 seconds after wireless operation has been resumed before opening and closing the battery door again. Opening and closing the battery door within 15 seconds will put the hearing instrument into flight mode again.

For more information about Flight Mode please refer to the relevant wireless hearing instrument user guide.

After having completed the fitting make sure to open and close the battery door to reboot the instruments saving all settings.

Optimize the wireless fitting environment

Even if all of the previous mentioned tips are followed, the stability of the fitting connections may be impacted by interference from other wireless sources in the environment. Interference may cause data  transfer issues, slow connectivity or loss of connections to the hearing instruments entirely.

Interference in the wireless fitting environment should, therefore, be minimized or avoided if possible by following the guidelines below:

• Minimize number of interfering wireless sources. Wireless activity from sources like WLAN, mobile phones and streamers should be minimized as much as possible. Even though the wireless protocol technology supports three audio streaming devices it is recommended to have no more than one streaming device (e.g. TV streamer) active while performing wireless fitting.
• Keep interfering wireless sources away from the fitting area. If interfering devices such as WLAN and streamers cannot be turned off during wireless fitting it is recommended to place these devices a minimum of 6 feet (2 meters) away from the hearing instruments and the Noahlink Wireless, ensuring that they are not between the Noahlink Wireless and the hearing instruments.

Troubleshooting Guide

confirming that Noahlink Wireless is powered. Launch the fitting software if not already launched.
No Connection| The USB port(s) in your PC have no power.| Not a Noahlink Wireless issue. PC service is required.
No Noahlink Wireless attached to the PC’s USB port.| Insert Noahlink Wireless activating a 2-3 second solid green light confirming that Noahlink Wireless is powered. Launch the fitting software if not already launched.
Obstacles between the Noahlink Wireless and the hearing instruments block the wireless signal.| Place Noahlink Wireless in line-of-sight of the hearing instruments.
The Noahlink Wireless is placed too far away from the hearing instruments.| Move Noahlink Wireless closer to the hearing instruments.
Hearing instrument low battery.| Always use fresh zinc-air batteries, which have not expired. Remove the sticker from the battery and let the battery breathe for 2 minutes before inserting and starting up the fitting.
Unstable/Lost Connection| Obstacles between the Noahlink Wireless and the hearing instruments block the wireless signal.| Place the Noahlink Wireless in line-of-sight of the hearing instruments.
---|---|---
The Noahlink Wireless is placed too far away from the hearing instruments.| Move the Noahlink Wireless closer to the hearing instruments.
A 2.4 GHz cordless telephone, a WLAN access point or another wireless device is powered or in use near to the fitting station doing wireless fitting with Noahlink Wireless.| Minimize the number of interfering wireless sources or move them away from the fitting area.Use a phone that is not 2.4 GHz.
Noahlink Wireless is sharing power source with one or more USB harddisks, resulting in Noahlink Wireless not having the required power available.| Remove the USB harddisk or use a powered USB hub to insure the required power. Lack of power is only an issue with USB harddisks which are very power- consuming.
