To charge the battery, place the receiver in the charging dock of the Transmitter. The LED bar must point upwards, magnets keep the receiver in the correct charging position.

The charging status LED on the front of the receiver will illuminate red, the charging status LED will switch to green when the battery is fully charged.

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 battery in optimum condition. The intelligent charging circuit within the system will prevent overcharging of the battery.
A 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.
If you have a second battery 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 smaller earbuds in the delivery.
To change the earbuds, gently pull them off the speaker’s 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. Replacements are available from your specialist dealer.

Using “Paris”

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 “Paris” under chin receiver
To use “ears”, proceed as follows:

Switch your audio source on (e.g. TV). If “Paris” is connected via the headphone jack or is operated with an optional microphone, you should set the volume of the sound source to a medium level. This is not necessary if “Paris” is connected via Toslink or RCA.
The receiver switches on automatically when spreading the speaker’s 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’s 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 transmission is established.
Adjust to the desired volume.
When you remove the receiver, it is automatically switched off. We recommend always returning 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 connect a maximum of 2 audio sources to the transmitter, for example, an analog 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.

Using “dynamic sound HS” to improve your sound experience

With “dynamic sound HS”, you have the possibility to find the ideal setting for your hearing experience. The integrated “dynamic sound HS” provides five selectable dynamic hearing profiles. These always calculate the sound dynamically according to the respective settings and are specially designed for users with hearing loss. “dynamic sound HS” is based on an algorithm developed by the German Fraunhofer Institute for Digital Media Technology IDMT in Oldenburg, which represents the latest in intelligent soundscape generation. The input signal is divided into different bands and each band is changed in its dynamic range. This change depends on the volume and sound profile selected by the transmitter. Finally, the sound is individualized on the separate frequency bands. After the separate frequency bands have been combined to form an overall signal, the system reproduces the sound. This is calculated dynamically and continuously in real-time so that the ideal adjustment is guaranteed for you at all times. Speech reproduction is calculated differently than, for example, music.

You can choose the most convenient sound profile for you from a choice of 5. The selected 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

There are two ways to select a preferred sound profile:

Press the tone control button on the bottom left of the receiver to select the desired profile. You can identify the set profile on the transmitter by the
5 sound profile indicator LEDs.
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” 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.

Communication amplification with the receiver
The audio stream of the transmission can be interrupted at any time, for example, if you want to talk to a person in the room. The receiver is ready to use this function 2 seconds after switching on. To do this, press the function button at the top of the receiver once. The receiver‘s integrated microphone now picks up the sounds of the environment and amplifies these via the receiver. The volume can be adjusted as usual. To end the function, press the function button again to resume the previous transmission. Please note that the volume setting of the microphone is independent of the volume setting of the
previous transmission. The volume you have set for the microphone is saved and used the next time you activate it. “dynamic sound HS” is not activated when the microphone is switched on.

Pairing transmitter and receiver
For “Paris” to function properly, the 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 At least 15 seconds, then according to the 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.
Under chin receiver: Wear the under chin receiver to switch it on.
Press the function button on the top of the receiver until the flashing status The LED on the transmitter lights up constantly. This indicates that the transmitter and receiver are now paired.
