By listening to your device with headphones or earbuds at high volumes, you run the risk of permanent damage to your ears. Even if you get used to listening at high volumes and it seems normal to you, you still risk the possibility of damaging your hearing. Reduce the volume of your device to a reasonable level to avoid permanent hearing damage.

If you hear ringing in your ears, reduce the volume or shut off your device. This device has been tested with the supplied earphones. In order to preserve your hearing, it is advised that you use only the following headphone models: the earphones supplied with your device, or any other headphones that respect the current regulations.

Do not use while operating a motorized vehicle. It may create a traffic hazard and is illegal in many areas.

You should use extreme caution or temporarily discontinue use in potentially hazardous situations created by obstructed hearing.

Even if your headphones or earphones are the open-air type designed to let you hear outside sounds, don’t turn up the volume so high that you can’t hear what’s around you.

Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. What sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting the volume of your device at a safe level BEFORE your hearing adapts.

To establish a safe volume level: a. Start your volume control at a low setting. b. Slowly increase the sound until you can hear it comfortably and clearly, and without distortion. Once you have established a comfortable sound level, leave it there.

This manual contains only some basic information about the device. Refer to the actual device for more exact details. All information is subject to change without prior notice.
