Pour votre sécurité, ne portez pas et ne posez pas ce casque à
proximité immédiate (moins de 10 cm) d'un pacemaker.
Surveillez vos enfants s'ils utilisent l'appareil. Ce produit n'est
pas un jouet.
Un casque d'écoute utilisé à un volume élevé risque de
provoquer de troubles de l'audition, en particulier s'il est porté
de façon prolongée.
Lorsque vous procédez à un réglage sur votre installation hi-fi
ou que vous branchez le casque sur l'installation, des bruits
dangereux pour l'oreille peuvent se produire si le son est réglé
sur un volume élevé. Pour cette raison, il faut toujours mettre le
son au minimum avant de passer d'une source à l'autre (radio,
platine, lecteur de CD...) ou de brancher le casque.
Pour ne pas mettre en danger votre sécurité au volant ni celle
des autres usagers de la route, n'utilisez jamais le casque lorsque
vous conduisez ou que vous roulez à vélo.

Al fine di garantire la sicurezza personale, fare attenzione che
queste cuffie non siano posizionate in prossimità del proprio
eventuale pace maker (con una distanza inferiore a 10 cm).
Sorvegliare i bambini quando utilizzano il dispositivo. Questo
apparecchio non è un giocattolo.
L'utilizzo delle cuffie ad alto volume, soprattutto se prolungato,
può danneggiare l'udito.
Maneggiare le manopole del Vostro sistema hi-fi o inserire le
cuffie quando il volume è troppo alto, potrebbe produrre dei
rumori che potrebbero danneggiare l'udito, soprattutto se il
volume è alto. Si consiglia pertanto di regolare il volume al
minimo prima di passare da una fonte all'altra (radio, giradischi,
lettore CD, ecc.) o prima di collegare le cuffie.
Per la sicurezza nel traffico, si prega di non usare mai le cuffie
mentre si guida o si va in bicicletta.

menyimpan earphone di sekitar (dekat dari 10 cm) alat pacu
jantung.
Awasi anak-anak saat menggunakan peralatan, produk ini bukan
mainan.
Mendengarkan earphone pada tingkat volume tinggi – khususnya,
selama waktu yang lama – dapat merusak pendengaran Anda.
Penggunaan sakelar pada sistem hi-fi Anda, atau penyumbatan
pada earphone dapat menimbulkan klik yang pada pengaturan
volume tinggi dapat memengaruhi pendengaran Anda.
Karena itu, selalu mengatur kontrol volume paling rendah
sebelum beralih di antara berbagai sumber (penala, pemutar
piringan hitam, pemutar CD, dll) atau penyumbatan pada
earphone.
Untuk keselamatan lalu lintas, jangan gunakan earphone selama
mengemudi atau berkendara.
