Insert the supplied battery into the receiver, until it clicks into place (the
battery only fits one way)
Charge the receiver completely and without interruption before first use. A
complete charge will take about 2 hours.
The battery status on the receiver lights up red when the battery level is low.
When system is in use and the battery in the receiver is low, the status LED
on the receiver flashes RED constantly, and you will hear a beep every 30
seconds. After a few minutes, the receiver will automatically switch off.
To charge the battery, place the receiver in the charging dock of the Trans-
mitter. The LED bar must point upwards, magnets keep the receiver in the
correct charging position.

charging status LED will switch to green when the battery is fully charged.

English 13
We recommend that you always place the receiver in the charging dock of
the transmitter when the system is not in use, this will always keep the bat-
tery in optimum condition. The intelligent charging circuit within the system
will prevent overcharging of the battery.
The second battery can be charged in the transmitter, additional batteries
are available from your dealer.
The replacement battery can be inserted into the charging slot on the right
side of the transmitter, please remove the cover over the charging slot.
The battery only fits one-way, extreme force is not required to insert it into
the transmitter.
During charging, the charging status LED for the spare battery lights up red
when the battery is fully charged this indicator changes to green.
We recommend that you swap the batteries once a week, this exercises
the batteries and allows them to reach their maximum lifespan.
Earbuds
As supplied, the larger silicone earbuds are fitted to the receiver‘s speaker
arms. If these buds are not comfortable for you, you will find a pair of small-
er earbuds in the delivery.
To change the earbuds, gently pull them off the speaker arms.
Then carefully insert the other two earbuds. Make sure that the earbuds fit
well and firmly.
From time to time, remove the earbuds from the receiver and clean them
with mild soapy water. Dry the earbuds thoroughly before replacing them.
In case of heavy soiling or damage, you should replace the earbuds. Re-
placements are available from your specialist dealer.

Using “earis XS”
Attention:
Your receiver can be set to a very high volume. To protect your own hear-
ing or the hearing of people with regular hearing capabilities, especially
children, from damage caused by excessive volume, please observe the
following instructions:
1. Set the receiver to a low volume level before using it.
2. During use, adjust the volume to a level that is comfortable for you.
3. Do not expose yourself to high volume for an extended amount of time.
Using the “earis XS” underchin receiver
To use “earis XS”, proceed as follows:
1. Switch your audio source on (e.g. TV). If “earis XS” is connected via
the headphone jack, you should set the volume of the sound source
to a medium level. This is not necessary if “earis XS” is connected via
Toslink or RCA.
2. The receiver switches on automatically when spreading the speaker
arms. Use the volume control on the receiver to adjust the volume to
a low level to protect your hearing. A low level of volume is indicated
when only a few LEDs on the volume indicator are lit. The more LEDs
on the volume indicator light up, the higher the set volume.
3. Adjust the earbuds so that they sit comfortably and without pressure
directly in front of your auditory canals. Look for the markings “L” and
“R” on the top of the speaker arms. The large silver volume wheel
should face forward for easy operation. Put the receiver on. The green
status LED at the top of the receiver indicates whether the receiver is
switched on.
4. The white status LED on the transmitter lights up white as soon as
the transmitter is in contact with the receiver and a transmission is
established.
5. Adjust to the desired volume.
6. When you remove the receiver, it is automatically switched off. We
recommend to always return the receiver to the transmitter‘s charging
dock so that the battery is always charged. If no audio signal reaches
the transmitter for more than 15 minutes, it will switch off automatically.

English 15
Audio source selection
You have the possibility to connecting a maximum of 2 audio sources to
the transmitter, for example an analogue stereo system and a digital TV
set. Use the “Analog/Digital” input selection switch on the left side of the
receiver to select the desired audio source.
Adjusting the volume
Use the silver volume control on the front of the receiver to easily adjust the
desired volume by turning it. The LED bar indicates the set volume. A low
level of volume is indicated when only a few LEDs on the volume indicator
bar are lit. The more LEDs on the volume indicator light up, the higher the
set volume.
Adjusting the balance
The balance control allows the volume distribution between the right and
left ear. Adjust the balance so that you hear equally well in both ears.
The balance control is located on the rear side of the receiver and can be
turned with the help of a coin.

16 English
Set listening profile for sound improvement
With our hearing profiles you have the possibility to find an optimal setting
for your hearing sensation. You can choose the most comfortable profile for
you from 5 sound profiles. The set profile is saved.
The following profiles can be selected:
1. strong sound alteration in the low frequency range
2. minor sound alteration in the low frequency range
3. no change
4. minor sound alteration in the high frequency range
5. strong sound alteration in the high frequency range
1. Press the tone control button on the top of the transmitter to select the
desired profile. You can identify the set profile on the transmitter by the 5
sound profile indicator LEDs.
You can connect a maximum of two receivers to one “earis XS” transmitter.
The transmitter calculates the sound profile, while the adjusted sound pro-
files are stored in the receiver.
The transmitter always calculates the set sound profile of the receiver that
is switched on first.

English 17
Pairing transmitter and receiver
For “earis XS” to function properly, transmitter and receiver must be paired.
As a rule, this has already been done during production and is carried out
as a standard on delivery.
However, if you want to use another receiver or perhaps have to replace
one later, it must first be paired with the transmitter.
A maximum of 2 receivers can be used simultaneously with one transmitter.
There are 2 possibilities to pair a receiver with the transmitter:
1. When inserting a receiver into the charging dock of the transmitter for at
least 15 seconds, the according receiver and the transmitter will be paired
automatically.
2. Press and hold the tone control button until the status LED on the front
of the transmitter starts flashing rapidly.
Underchin receiver: Wear the underchin receiver to switch it on.
Press the function button on the top of the receiver until the flashing status
LED on the transmitter lights up constantly. This indicates that transmitter
and receiver are now paired.
