Play a song on your mobile/MP3 and while playing turn up the volume to the maximum from your mobile. Check if it is heard on the earpiece.
⚠ If the song is not heard through the earpiece, but you do hear the sound of the radio without tuning, check that you have the induction collar on your neck and that the mobile is correctly connected and with the volume at maximum. If it doesn't work try another mobile. If you need more help contact us: WhatsApp +34 644 507 888 o Email.
⚠ In some iPhone models, a compatibility failure has been detected in the use of the device with non-original adapters when making a phone call. You need to use an original adapter or use another mobile.
⚠ If you cannot hear the sound similar to a radio without tuning, check that the battery is correctly inserted with the positive pole + facing up and screw the cover back on carefully. If the lid is not correctly aligned it will make this noise. Check that the battery is charged and try the other battery included in the Kit.
