2AWZ8-AIR3TWS EARBUDS

Mobiltelefons bedienen. Wenn Sie klicken, um einen Anruf auf Ihrem Mobiltelefon anzunehmen, wird standardmäßig das eingebaute Mikrofon Ihres Mobiltelefons verwendet. Die Nutzung von WhatsApp, Skype, Wechat und anderer Kommunikationssoftware kann durch die Qualität des Mobilfunknetzes beeinträchtigt werden. 5. warum kann ich die Funktion auf den Ohrhörern nicht nutzen? Für diese Funktion muss das Gerät mit den Ohrhörern gekoppelt werden, um AVRCP (Audio/Video-Fernbedienungs- profil) zu unterstützen. Bitte stellen Sie sicher, dass Ihr Gerät dies unterstützt. MANUEL DE L'UTILISATEUR Mise sous tension : Retirez les deux oreillettes de l'étui de chargement. Mise hors tension : Remettre les deux écouteurs dans l'étui de charge Jumelage des écouteurs l'un avec l'autre : Retirez les deux écouteurs de l'étui de chargement, le témoin lumineux des deux écouteurs clignote alternativement, puis attendez que les deux écouteurs s'appairent automatiquement l'un à l'autre (IMPORTANT). Une fois appariés, le témoin lumineux d'un seul écouteur clignote alternativement. Les écouteurs sont maintenant prêts à se connecter à votre appareil. Après la première connexion réussie, la prochaine fois que vous sortirez les écouteurs de l'étui de chargement, ils s'allumeront automatiquement et se connecteront à l'appareil connecté. Lecture/pause : Appuyez une fois sur le bouton L/R pour lire ou mettre en pause la musique. Chansons précédentes/suivantes : Appuyez deux fois sur le bouton L/R pour changer de musique. Répondre à un appel entrant/terminer un appel : Appuyez deux fois sur la touche L/R pour répondre à un appel entrant. Pendant l'appel, appuyez deux fois sur la touche pour mettre fin à l'appel. Rejeter l'appel : Appuyez longuement sur la touche L/R pendant environ 4 secondes pour rejeter l'appel. Assistant vocal : Appuyez trois fois sur le bouton L/R pour contrôler l'assistant vocal. Remarque : votre appareil doit prendre en charge cette fonction. RÉSOLUTION DES PROBLÈMES 1.Pourquoi une seule oreillette peut-elle jouer de la musique ? 1) Vérifiez d'abord dans la liste de votre téléphone si les écouteurs ont déjà été connectés. Si c'est le cas, veuillez d'abord supprimer ou retirer de la liste tous les appareils que vous avez connectés et désactivez la fonction de recherche sur votre téléphone ( PAS déconnecter, mais supprimer ). Placez les écouteurs dans l'étui de chargement. Répétez ensuite les étapes d'appairage. 2)Si le problème ne peut être résolu par le point 1), retirez les deux écouteurs de l'étui de chargement, appuyez sur les boutons L/R 6 fois en même temps, le voyant lumineux des écouteurs clignotera rapidement, puis remettez les écouteurs dans l'étui de chargement. Répétez ensuite les étapes d'appairage. 2.comment changer la langue de l'annonce vocale en anglais ? Lorsque le message vocal est dans une autre langue, déconnectez les écouteurs du téléphone ou supprimez l'appareil que vous avez connecté de la liste, les écouteurs passeront en mode d'appairage, puis appuyez 5 fois sur le bouton pour basculer la langue sur l'anglais. 3. l'appareil demande un pilote/ne peut pas s'appairer Assurez-vous que votre téléphone autorise les nouvelles connexions et que le nombre maximum d'appareils autorisés n'est pas atteint. L'appareil ne peut être utilisé qu'avec des téléphones intelligents (pour IOS, Android), et ne convient pas aux PC, téléviseurs et consoles de jeux. Certains ordinateurs portables peuvent être directement connectés pour être utilisés, s'ils sont invités à télécharger le pilote ou certaines applications, ils ne sont pas compatibles. 4. pourquoi ne puis-je pas utiliser la fonction mains libres ? Répondez aux appels en utilisant les écouteurs au lieu du téléphone portable. Si vous cliquez pour répondre à un appel sur votre téléphone portable, le microphone intégré de votre téléphone portable est utilisé par défaut. L'utilisation de WhatsApp, Skype, Wechat et d'autres logiciels de communication peut être affectée par la qualité de l'appel sur le réseau cellulaire. 5. pourquoi ne puis-je pas utiliser la fonction des oreillettes ? Cette fonction nécessite que l'appareil soit couplé aux écouteurs pour prendre en charge le profil AVRCP (profil de commande à distance audio/vidéo). Veuillez vous assurer que votre appareil est compatible avec cette fonction. MANUALE D'USO Accensione: Estrarre entrambi gli auricolari dalla custodia di ricarica. Spegnimento: Riporre entrambi gli auricolari nella custodia di ricarica. Accoppiamento degli auricolari tra loro: Estrarre entrambi gli auricolari dalla custodia di ricarica, la spia di entrambi gli auricolari lampeggia alternativamente, quindi attendere che i due auricolari si accoppino automaticamente tra loro (IMPORTANTE). Una volta accoppiati, la spia di un solo auricolare lampeggia alternativamente. Ora gli auricolari sono pronti per essere collegati al dispositivo. Dopo il primo collegamento riuscito, la volta successiva basta estrarre gli auricolari dalla custodia di ricarica per accenderli automaticamente e collegarli al dispositivo connesso. Riproduzione/pausa: Premere una volta il pulsante L/R per riprodurre o mettere in pausa la musica. Brani precedenti/successivi: Premere due volte il tasto L/R per cambiare musica. Risposta alle chiamate in arrivo/Fine chiamata: Premere due volte il pulsante L/R per rispondere alla chiamata in arrivo. Durante la chiamata, premere due volte il pulsante per terminare la chiamata. Rifiutare la chiamata: Premere a lungo il tasto L/R per circa 4 secondi per rifiutare la chiamata. Assistente vocale: premere tre volte il tasto L/R per controllare l'assistente vocale. Nota: il dispositivo deve supportare questa funzione. RISOLUZIONE DEI PROBLEMI 1.Perché solo un auricolare può riprodurre la musica 1) Controllare innanzitutto l'elenco del telefono per verificare se gli auricolari sono già stati collegati in precedenza. In caso affermativo, eliminare o rimuovere tutti i dispositivi collegati dall'elenco e disattivare la funzi…

FCC 47CFR §2.1093 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in KDB 447498 D01 General RF Exposure Guidance v06 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. Report No.: LGT24F073HA01 Page 7 of 9 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] • [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,where f(GHz) is the RF channel transmit frequency in GHz. Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
