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.

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
