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.

Using “earis XS”

Attention:

Your receiver can be set to a very high volume. To protect your own hearing or the hearing of people with regular hearing capabilities, especially children, from damage caused by excessive volume, please observe the following instructions:

Set the receiver to a low volume level before using it.
During use, adjust the volume to a level that is comfortable for you.
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:

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.
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.
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.
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.
Adjust to the desired volume.
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.

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

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.

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:

strong sound alteration in the low frequency range
minor sound alteration in the low frequency range no change
minor sound alteration in the high frequency range
strong sound alteration in the high frequency range
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 profiles are stored in the receiver.
The transmitter always calculates the set sound profile of the receiver that is switched on first.

Mute-Function

The receiver has a Mute function which will allow the user to interrupt the sound coming from the system without removing the receiver.

To use this feature, a short press of the function button on the top of the receiver will cause the LED indicator to flash briefly, sound is then interrupted.
To switch the sound back on simply press the function button again, the LED indicator will light up constantly and the normal sound will resume.

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:

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.
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.
