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!
