Solutions to improve the quality of life

The M Acoustic Earhook coupled with the Marvel CI sound processor is designed for CI candidates and recipients who have aidable lowfrequency hearing in the implanted ear.
This solution provides acoustic amplification of the low frequencies via hearing aid technology, in combination with electrical stimulation of the high frequencies in the same ear via cochlear implant technology.
The M Acoustic Earhook takes advantage of natural acoustic hearing to provide the benefits of combined stimulation to recipients with unilateral or bilateral Marvel CI(s).
The M Acoustic Earhook is compatible with the Naída™ CI M90 and Sky CI™ M90 sound processors.
SDS Power domes are suitable for moderate hearing loss and offers a tighter fit than a Vented dome. Whereas vented domes are suitable for mild-to-moderate hearing loss and are beneficial if occlusion is a concern.
Advanced Bionics part numbers: CI-5851-001 to CI-5851-010

ASSEMBLING THE M ACOUSTIC EARHOOK
Follow the steps below to setup the device appropriately:
• The M Acoustic Earhook is available in 5 different lengths
(00, 0, 1, 2, 3) for either the left or right ear.
• The Measurement Tool helps to determine the appropriate
length of the Acoustic Earhook to
accommodate different ear shapes and sizes.
• The Pin Removal Tool is used for attaching the M Acoustic
Earhook to and from the sound processor.
• Confirm that a CeruShield wax filter is inside the
receiver. The receiver ships with a wax filter already
inserted.
• Select a suitable earpiece option to attach to the receiver
of the M Acoustic Earhook. Ensure a comfortable
fit and seal in the ear canal for good retention. When
mounting the earpiece on to the receiver, there is a
tactile click upon attachment.
CARE AND MAINTENANCE
Earwax Protection
• The M Acoustic Earhook is equipped with a CeruShield wax
filter to protect the receiver from
earwax damage.
• Check the earwax protection regularly and exchange it if it
looks dirty or if sound quality is reduced.
• The CeruShield earwax filter should be replaced at least
every four to eight weeks.
General Care
• When not in use, store the sound processor and M Acoustic
Earhook in the equipment case provided.
• Ensure the M Acoustic Earhook is not placed within
proximity of the headpiece magnet, as the magnet may damage the
receiver.
• Visually inspect the device daily for earwax and moisture
deposits in the M Acoustic Earhook.
• Wipe the earpiece daily with a dry tissue.
• If a dome is used, it should be replaced every three
months, or when it becomes brittle.
• To clean the M Acoustic Earhook:
– Remove the dome from the receiver.
– Using a lint-free cloth or moist cleansing wipe, gently
clean the dome and receiver unit. Never use cleaning agents such as
household detergents.
– Prior to reattaching the dome to the receiver, ensure that
all parts are completely dry.
