Note
When the headphones had not been used for a long time, it may take a while for the POWER indicator to light up in
red. In this case, do not disconnect the micro-USB cable from the headphones. Wait until the POWER indicator
lights up in red.
Charge in an environmental temperature of between 5°C and 35°C. Otherwise, the battery may not fully charge.
If the battery is fully charged, the POWER indicator may blink and go off, and charging may not start. This is not a
malfunction.
When storing the headphones for a long time, avoid a place subject to high temperatures. When storing the
headphones for more than a year, charge the battery every six months to prevent over discharge.
If you haven’t used the headphones for a long time, the life of the rechargeable battery may become short. This will
improve when you repeat the charging and discharging process several times.
