3. Use of the power adapter and internal battery:
3.1 Use of the power adapter: there is a lithium battery in this instrument. Turn on
the power switch and it is ready to use. You can also plug in the provided power
adapter to charge as well as to supply power to operate the instrument at the
same time. Plug the standard plug of AC power adapter into the corresponding AC
outlet, and plug the other end into the ‘DC5V-9V’ jack on the back of the electronic
piano (after plugging in the power adapter, the ‘green’ charging indicator will light
up, showing that the battery is being charged). Turn on the power switch to use the
instrument (after turning on the power switch, the ‘red’ power indicator and the
‘green’ charging indicator will light up at the same time. When the battery is fully
charged, the ‘green’ charging indicator will go out).
3.2 Use of internal battery: the piano is equipped with a 1800 MAH lithium battery.
If you need to use the electronic piano when going out, you can use the internal
battery to power it. When the battery is fully charged, you can turn on the power
switch to start using.
3.3 Charging: when the battery is too low, there will be smaller, worse or inaccurate
sound, flashing red power indicator or continuously restarting instrument. It is
necessary to charge the battery in time. Plug the provided ‘power adapter’ into the
AC outlet, and plug the other end into the DC jack of the piano to charge (at this
time, the ‘green’ charging indicator will light up. When the battery is fully charged,
the ‘green’ charging indicator will go out).
Warning: When the ‘power adapter’ is connected, no matter if the ‘power switch’ is
‘On’ or ‘Off’, the piano is being charged. To avoid battery damage, overheating or
fire explosion after charging for a long time, please disconnect the ‘power adapter’
from the AC outlet when you are not using the piano as well as when you don't
need to charge it.
Note:
1.1. It takes about 2-3 hours to fully charge the battery. Do not charge it for more
than 6 hours. Charging too long may damage the battery or cause overheating
and fire explosion.
1.2. When charging, keep special watch to prevent unexpected accidents.
1.3. Use the power adapter provided by our factory only. Wrong power adapter may
cause overheating as well damage the internal components of the electronic piano.
1.4 The adapter for charging is placed in the side foam of the packing box,
please make sure take it out before throwing away the box.
