Cautions:
1. Most mobile phones have headset power on screen display. When headset battery low,
the headset will beep and the indicator will turn red. Please charge it in time.
2. Do not connect the charged headset to the charging circuit for a long time. Overcharging
will shorten battery life.
3. Please keep the headset battery safely. Do not put the battery or the headset into fire or
water to avoid explosion.
4. Do not use headset with high volume for extra long time, which may cause hearing loss.
Always listen at a moderate level.
5. Do not connect the high voltage device to charge, which may cause damage to the
headset.
6. Make sure that the headset is fully charged before using it if long time no use.
7. Lifetime of the battery will be significantly reduced if your device is left
uncharged for a long time. We therefore recommend that you recharge your device at least
once a year.
