the balance adjusted by your hearing aid acoustician.

왘Using a 2 mm slotted screwdriver, turn the balance control 3to

the left Lor right Rin order to increase the volume for the corre-

sponding ear.

Adjusting the bass attenuation

the headphone systems of the A 200.

Cleaning and maintaining the product

왘Before cleaning, disconnect the charger from the mains.

왘Only use a slightly humid cloth to clean the product.

The more holes you seal with the sealing tape,

the greater is the bass attenuation. This increases

the speech intelligibility without increasing the

volume – which is an advantage for people with a

hearing impairment at high frequencies.

CAUTION

Liquids can damage the electronics of the product!

Liquids entering the housing of the product can cause a short-circuit

and damage the electronics.

왘Keep all liquids far away from the product.
