Using the A 200 personal sound amplifier  
WARNING  
Danger of hearing damage!  
Listening at high volume levels for long periods can lead to per-  
manent hearing defects.  
̈ Before putting the A 200 on, set the volume to a low level.  
̈ Then adjust a comfortable sound amplification.  
WARNING  
Interference due to magnetic fields!  
The product generates stronger permanent magnetic fields that  
could cause interference with cardiac pacemakers and implanted  
defibrillators (ICDs).  
̈ Always maintain a distance of at least 3.94” (10 cm) between  
the ends of the earbows with the ear pads and the cardiac  
pacemaker or implanted defibrillator.

amplification 6. Position “1” corresponds to a low sound amplification  
different settings for the sound  
and position “6” corresponds to a very high sound amplification.  
̈ Use the control 5 to adjust the volume to a sufficient and comfort-  
able level.

Cleaning and maintaining the product  
Adjusting the balance  
The balance control allows for right/left volume adjustment. Adjust the  
balance so that you hear equally well with both ears. If necessary, have  
the balance adjusted by your hearing aid acoustician.  
̈ Using a 2 mm slotted screwdriver, turn the balance control 3 to  
the left L or right R in order to increase the volume for the corre-  
sponding ear.

Adjusting the bass attenuation  
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.  
̈ Use the two supplied sealing tapes to seal the small holes in back of  
the headphone systems of the A 200.  
Cleaning and maintaining the product

̈ Keep all liquids far away from the product.  
̈ Do not use any solvents or cleansing agents.
