. Radio range
The transmitter is designed to have a radio signal range of
metres under optimum conditions.
The following conditions may result in a reduced range:
Signal transmission through building structures or
vegetation
Interference from TVs, computer monitors and mobile
phones. Under certain circumstances, this may prevent
the receiver from functioning at all.
Positioning of the transmitter at an unfavourable distance
from surfaces which reflect radio waves, for example floors
and walls. This may lead to the signal wave being weakened
or even cancelled out by the reflected wave.
Metallic objects reduce the range due to the shielding
eect of the metal.
Particularly in towns and cities, there may be many other
sources of radio waves which can disrupt the original signal.
Having units operating at similar frequencies located close
to one another may also result in mutual interference.
5
. Channel selector A, B, C
With the channel selector you can change the frequency of the
transmitter. If channel A is distorted you can change to another
channel.
NOTE: If the transmitter is switched to another channel, the
receiver also has to be set to another channel.
See specifications.
The channel selector is located on the rear side of the
transmitter or receiver.
Transmitter and receiver must both be set to the same channel.
6
. Volume adjustment of the
receiver
There is no ON/OFF switch!
The receiver automatically switches on when worn.
The stethoscope headset will switch o automatically when
you remove it.

7
. Battery pack replace
If the sound quality of the receiver becomes noisy and distorted
you should replace the battery pack with a charged one or
charge the receiver, including battery, in its cradle.
WARNING: Do not force the battery pack into the charger or
receiver!
How to get the most out of your rechargeable batteries
Please make sure that both batteries are used on a regular
basis. Constantly recharging the batteries will shorten their
service life. That’s why you should exchange the batteries
in the hearing aid with the batteries in the charging station
regularly (for best results, once a week).

. Maintenance of the headset
receiver
The ear pieces have to be cleaned or exchanged if dirty.
To replace, please use the silicone earpieces for DIR headsets.
9
. Replacing the silicone covers
with the transparent cover of the
volume control
The transparent cover has the following protective functions:
It prevents any unintentional changes in the volume level.
It protects dust and liquids from coming into contact with
the volume control.
