When the earpiece has been correctly inserted in the left ear, place the Kit as it appears in the image, remembering that the induction collar should always be on the neck under clothing so that the earpiece receives the sound.
Play the song, recording or phone call by turning the volume up to the maximum on your mobile to check if the volume it provides is enough a penguin (sufficient in most cases) if we have inserted the earpiece correctly, if the volume is maximum, the collar has enough charge and is located on the neck).
If you hear very low, Also insert the other earpiece into your right ear or try turning up the volume on the Nano V5 Neckloop (different volume than mobile).
To increase the volume of the neckloop (different volume than mobile) hold down the + button of the Nano V5 while the earpiece is on the left ear and the neckloop on the neck. When you hear a whistle means that the volume is at maximum* on the necklace.
(A single earpiece in the left ear is recommended, since when trying to insert one in each ear, the first one will be misplaced when introducing the second one). (It is VERY likely that if we do not hear well with an earpiece in the left ear it is because we have not inserted the earpiece correctly, the volume is not the maximum in the mobile, the induction collar does not have enough charge or it is not on the neck).
*The volume to the maximum in the inducer collar drastically reduces the autonomy. You must adjust the volume to the maximum on the mobile and to the minimum audible (usually 50-70%) on the neckloop (you can decrease the volume by holding down the volume – button and increase it by holding down the + button).
