Attention
The product has been installed with battery, making it applicable to the outdoor
singing, advertisement, recreation and other activities. Please charge the battery
before using it outdoors, so as to guarantee that the machine can be used for a longer
time outdoors. The machine has been set with power switch circuit. When you
connect the adaptor to the power and insert the plug to the charging interface, the
machine will switch to the power supplied by the adaptor automatically and charge
the built-in battery. When the adaptor interrupts the power, the machine will
intelligently switch to the built-in battery for work continuously. When adaptor is used
to charge the battery, the integrated intelligent charging circuit within the machine
will give hints about charging and the charging indicator lamp will light. After
charging is finished, the intelligent charging circuit will give hint to that that the
charge has been fully charged and light the charging indicator lamp. At this moment
you can close the AC power of the adaptor. If you still use adaptor in the machine to
work, the charging circuit will automatically cut off the charging circuit and it is
unnecessary for you to worry about the charging breaking. You shall notice that the
battery has certain service life and it is beyond the warranty scope of the company.
Under general circumstances, the built-in battery needs charging 8-10 hours. With
more charging times, the battery volume will change and full charging time will
reduce accordingly. When the battery is out of charge after being used for a short time,
please change the built-in battery. The user shall also notice that if the electricity
quantity of the battery is reduced when using the machine outdoors, please close the
power switch on the rear plate and charge the built-in battery within 24hours. If the
electricity quantity of battery is totally consumed, the situation that the battery can not
be charged and the service life is expired will happen. When you don’t use the
machine for a long time and leave it alone, please charge the battery every six months,
so as to avoid the invalidity of battery.
Instruction of U disk MP3 encoding playing
When you need to use the built-in MP3 encoding function, please format your USD
disk (U disk for short below) as FA-T32 format in computer first and then copy the
file in MP3 format in U disk. When reading U disk, the encoding system will engage
in encoding playing according to the generation sequence of MP3 songs file.
Therefore, the song which is copied to U disk first will be played in priority or vice
versa. When the user needs to play according to the specific sequence, they can
arrange the copying sequence. If the files copied to U disk can not be played, please
inspect whether the file format is in MP3 format. If not, please switch to MP3 format
in computer and then copy to U disk in order to play normally. When copying MP3
file, you shall copy to the catalogue of U disk. It is suggested to delete all the
unnecessary files and file catalogues in order to reduce the occurrence of reading error
when the encoding is played. When the user buys U disk, please select the ones with
better quality and internal encoding supporting
64MB/128MB/256MB/512MB/1GB/2GB/4GB/8GB and other volumes. During the
playing process, please make it far away from the places with high temperature, high
magnetic field and high frequency interference. In case of crash, please close the
power and restart for recovery!
