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 adapter to the power and insert the
plug to the charging interface, the machine will switch to the power supplied by the adapter
automatically and charge the built-in battery. When the adapter interrupts the power, the
machine will intelligently switch to the built-in battery for work continuously. When adapter 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 adapter. If
you still use adapter 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

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!
