Battery
Before you use it for the first time, the L7A must be fully charged.
To do this, connect L7A 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 L7A 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 L7A 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 L7A 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 “L7A”
Once your telephone is paired with the L7A, the two devices will
connect to each other automatically each time that the L7A is
switched on. It is not possible to simultaneously connect several
devices to L7A.
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.
