Model number L3 Battery Before you use it for the first time, the L3 must be fully charged. To do this, connect L3 to your computer via the USB to micro- USB cable. The indicator on the side of the right ear cup illuminates with a red light to show that the device is charging. Once charging is complete, the indicator light turns off (1). When the battery is flat, you can still use the L3 to listen to music if your audio player is connected to the headset via the Jack to Jack cable. Conversely, the telephone and Bluetooth music transfer functions and touch sensitive panel are not available (2). Switching the L3 on/off Press the button (1) to switch the product on/off. Wearing the headset Adjust the band without forcing it, so that the headphones will fit comfortably over your ears, then put the headset on, using the letters (L) and (R) to help you distinguish left and right. Bluetooth Connection Before L3 can be used with your telephone or Bluetooth audio player, the two devices must be paired(3) . Once the two devices have detected each other, it is no longer necessary to pair each time. 1. From your telephone or Bluetooth audio player, start a search for Bluetooth peripherals. 2. Select “L3” Once your telephone is paired with the L3, the two devices will connect to each other automatically each time that the L3 is switched on. It is not possible to simultaneously connect several devices to L3. All Bluetooth Audio device Listening to music at high volumes for long periods can lead to hearing problems. We do not recommend using these headphones at maximum volume, particularly for long periods of time. To protect your hearing, turn down the volume of your music player before connecting your headphones. After putting on the headphones, gradually turn up the volume until you reach a suitable level. Sound levels are measured in decibels (dB). Exposure to sound 85 dB or above may result in gradual loss of hearing. Monitor your use. Hearing loss depends on the intensity of the sound and the duration. The higher the volume, the less your exposure capacity will last. The lower the volume, the longer your exposure period can be. Be responsible: pay attention to your environment (acoustic) when you are wearing your headphones and listening to music or the radio. Avoid hazardous behavior that may cause an accident for you or somebody else (pedestrians, motorcyclists, drivers, cyclists) or cause damage to property when you are wearing your headphones. Lezun would like to inform you that the use of stereo headphones is strictly forbidden when driving a motor vehicle. Lezun also recommends not listening to music or the radio through your headphones when riding a bicycle, a scooter or any other means of transport for which it is not compulsory to wear a helmet. Lezun can not accept any responsibility if you choose to ignore these warnings.
