FAQ
Q: How many SurfLink Medias can I use in my home or office?
A: While there are no numerical limits to the number of SurfLink Medias which can be used within
a building, it is good practice to separate the units by 40 feet (13 meters) or more to minimize
unintended interference.
Q: What electronic devices can be connected to the SurfLink Media?
A: Any electronic device with an Audio Output jack (RCA connectors, Digital Optical, Digital Coaxial) can
be directly connected to the SurfLink Media. In addition, an External Microphone (part# 52640-000)
can provide indirect audio input to the SurfLink Media when a direct connection is not possible.
Q: Does a patient need to pair their hearing aids to a SurfLink Media?
A:
1. It is not necessary for a patient to pair their hearing aid to the SurfLink Media.
2. During a Fitting Session, a professional can enable/disable streaming in each hearing aid memory.
In use, a SurfLink Media streams audio to all "streaming-enabled" hearing aids within range.
Depending on the hearing aid set up, each hearing aid can begin streaming either "Automatically"
or "Manually" upon a SurfLink Advanced Remote "Start Streaming" command ("star" button).
Q: How many Hearing Aids can stream audio with the same SurfLink Media?
A:
The SurfLink Media is capable of streaming to multiple hearing aids in a typical listening environment.
Q: How do I Start streaming?
A:
1. Power on the hearing aids.
2. Turn on the Audio Source connected to the SurfLink Media.
3. Turn on the SurfLink Media.
4. If hearing aids are set up for "Automatic" streaming, then streamed audio should start when
hearing aids are within RANGE.
5. If hearing aids are set up for "Manual" streaming, a "Start Streaming" command via the "star"
button on the SurfLink Advanced Remote will begin streaming to hearing aids within RANGE
of the SurfLink Media.
6. If the audio stream does not start, wait five seconds, and press the "star" button on the SurfLink
Advanced Remote again.
Q: What are my options to Stop streaming?
A:
1. Press "star" button on the SurfLink Advanced Remote.
2. Move to a hearing aid memory environment that isn't set up for audio streaming.
3. Turn off the Audio Source.
4. Turn off the SurfLink Media.
Q: How long do hearing aid batteries last when streaming?
A: Anytime a hearing aid is connected to a SurfLink Media, the battery will be discharged at an
accelerated rate. The actual discharge rate will vary according to hearing aid matrix, transmitted sound
variety (silence vs. rock music), how long a streaming session lasts, patient's audiogram, etc. As many
variables come into play, there is no exact answer to how long batteries may last when using a SurfLink
Media for a few hours per day. However, combining typical usage patterns with 40-60 gain receivers,
typical Wireless hearing aid battery life may decrease by 15% - 35%.
Q: What does the bottom slider bar (RANGE) control?
A:
In general, the RANGE setting (lower slider bar) on the SurfLink Media modifies the distance that
hearing aids will be able to start streaming. It has no effect on the active audio streaming distance,
which is fixed and not user adjustable. If a patient is in "Manual" streaming mode, pushes "star
button," and they are outside of RANGE broadcast distance, then no audio stream will be heard. Both
"Automatic" mode and "Manual" mode must be close enough to RANGE to activate "streaming."
Once streaming is active, "Manual" mode and "Automatic" mode behave the same.
Note
If RANGE slider is farthest left (one blue dot), this is a test mode (6" – 12" activation distance). Two blue dots typically
activates within 4'-8'.
Q: After I start streaming audio, does the RANGE setting matter anymore?
A:
In rare cases where there is strong local interference, streaming audio may be discontinued until
the patient moves back into the RANGE setting distance, whereby the hearing aid reacquires the
streamed audio from the SurfLink Media.
Q: How do I adjust sound volume and/or hearing aid microphone levels used
during streaming?
A: • During a fitting session, the professional sets up hearing aid microphones to be either On
(0 to 9dB attenuation) or Off during streaming in all hearing aid memories.
• During a streaming session, the SurfLink Advanced Remote or hearing aid user control adjusts
the hearing aid volume, effectively changing both streaming volume AND environmental sound
levels (received through hearing aid microphones if the hearing aid microphone is set to be
On during streaming).
• Volume adjustment made using the top slider bar on the front of the SurfLink Media changes
streamed audio level, but does not change environmental sound levels.
