Important safety information

As outlined in Lyric user guide

Please read and maintain the following important

safety information when you start working with

Lyric2.

Please refer to the Lyric/Lyric2 User Guide for important

safety information, compliance information and

information about FDA regulations.

If any abnormalities are detected during otoscopy the

customer must be referred to an ENT doctor. As for any

other hearing aid, it is recommended to have the ear

canal assessed by an ENT doctor prior to the initial sizing

and fitting of Lyric2.

Changes or modifications to the hearing aid that were

not explicitly approved by Phonak are not permitted.

Such changes may damage the ear or the hearing aid.

Phonak is not responsible for situations resulting from

the insertion of a modified device.

The SoundLync contains a magnet. If a medical device

like a pacemaker is used, read the specific user guide to

clarify possible impact of magnetic fields to the medical

device. The SoundLync must not be placed in the breast

pocket. Keep a distance of at least 15cm (6 inches)

between the SoundLync and the medical device.

The hearing aid is a potential choking or swallowing

hazard so it should be kept out of reach of children,

mentally challenged people and pets. If hearing aids are

swallowed, consult a medical practitioner immediately!

The hearing aids must not be used in explosive areas

(mines or industrial areas with danger of explosions).

If Lyric2 stops working for any reason, it must be

removed within 24 hours and the patient should see a

hearing care professional to check the ear canal.

Do not put cotton swabs or anything else in the ear

canal. They could damage the hearing aid and/or injure

the ear.

Scuba diving or diving underwater as well as skydiving

may cause injury to the ear or damage to the hearing

aid. These activities are prohibited while wearing Lyric2.

Medical imaging procedures, such as MRI scans, may

cause injury to the ear or damage the hearing aid. Lyric2

must be removed prior to having an MRI scan because it

contains metallic parts.

Complete submersion of the ears while wearing Lyric2 is

not recommended unless a custom made ear plug is

worn as this may cause damage to the hearing aid.

Lyric2 is designed for single-use. Once removed, it

cannot be reinserted.

Using the SoundLync: the SoundLync should not rest

against the skin of those with allergies to nickel.

Lyric2 work environment set-up instruction

Getting started with the microscope

Please carefully follow the “instruction for use” enclosed in

the packaging when assembling your microscope.

Aim

To have an ergonomic and comfortable seating position

Work effectively on patients’ ear

Smallest possible space requirement

Legroom for the patient

Space requirement

The space provided should be at least 180cm x 200cm.

Facts about the microscope

Magnification: 6,4 times

Weight: 76kg

Working distance: approx. 20cm

Recommended assembly

The recommended layout of the microscope and chair is illustrated

to the right. The advantages are:

The hearing care professional is able to turn the patient chair

without any difficulty.

The alignment of the microscope in this way ensures the best

possible working position for both ears.

A right angle between the short and the long arm of the

microscope improves the handling of the microscope.

Once the microscope is assembled, it is crucial to apply the

breaks and to adjust the resistance of the joints. It is

recommended to opt for a higher resistance for the rotation

of the shorter arm and a lower resistance for the rotation of

the longer arm of the microscope. This will minimize the side

deviation while moving forward with the microscope.

The microscope should be set at a right angle to the long arm.

To perform otoscopy on the patient‘s opposite ear, the chair is

turned around while the patient remains seated. The position

of the hearing care professional and the microscope remains

unchanged throughout.

Step 1 Adjusting eye distance

Important

It is not necessary to have a sharp focus during this step! Before

working with the microscope the eye distance of the oculars needs

to be adjusted to avoid shadows and to ensure a round field of

vision.

First, the oculars are set to the widest distance possible by

turning the dial located on the lefthand side. People who wear

glasses must push back the rubber eye-piece cushions to ensure

the correct distance is maintained between the eyes and the

ocular.

Switch on the light and look through the eye-pieces. Slowly turn

the dial to decrease the distance between the oculars, until a

round sector is visible. There should be no shadow, overlapping

or double images in the centre. Once you are happy with this

image, there is no need to adjust the dial further.

Step 2 Focusing the microscope

Setting the focus of the microscope is only achieved by adjusting

the distance between the microscope and the object to be

examined. There is no need to change the position of the knob or

the eye-pieces in order to get a focused image.

Advice: People who must wear corrective lenses due to spherical

refractive errors when viewing distant objects may set the

corresponding dioptre number on the eye-pieces and adjust the

focus. For further information please refer to the paragraph

below: “Positioning of the microscope oculars“.

Start with the microscope 20cm away from the patient‘s ear.

Slowly move the microscope forward towards the ear until the

image is focused.
