Q&A
Q: Why is the storage capacity displayed on the operating system
inconsistent with the nominal value?
A：As we all know, binary is used in computers, so that the calculation of
capacity in the operating system is based on every 1024 as a unitary, every
1024 bytes is 1KB, every 1024KB is 1MB, and every 1024MB is 1GB; and the chip
Storage vendors use the decimal system for calculating capacity, that is,
every 1000 is a single system, every 1000 bytes is 1KB, every 1000KB is 1MB,
and every 1000MB is 1GB. The difference between the two systems causes the
flash disk and mobile hard disk capacity to be slightly different from the
nominal capacity. Take an example: the calculation method of chip storage
manufacturer’s capacity: 2G=2000MB=2000000KB.
Converted to the counting method in the operating system:
2000000KB/1024=1953.125MB,1953.125MB/1024=1.91G In addition, the player’s
internal font and system files will use a small part of the memory, so the
memory capacity displayed in the operating system will be less than the
nominal value, which is in line with the relevant standards.
Q: What should I do if the product is abnormal?
A：
- After restarting, whether it returns to normal.
- Charge the battery with the charger to activate the battery, and try to restart the battery under the premise of ensuring a certain amount of power.
- It is recommended that you ask professionals to upgrade the system. In order to prevent abnormal phenomena, on the one hand, please be careful not to operate too fast, it is recommended to operate one by one; on the other hand, if the battery power is low, please charge it in time.
Q: Why sometimes the standby time is too short?
A：The use time of polymer batteries will vary with the temperature environment
and usage conditions. If the ambient temperature is too high or too low, the
battery life will be affected. It is recommended to use this machine at room
temperature! From the perspective of usage, it is also affected by factors
such as increasing the volume, turning on sound field effects, and frequent
operations, and the actual usage time will also vary to a certain extent.
Q: How to solve the garbled folder?
A：It means that the file allocation table (FAT) of this machine has been
damaged, which may be caused by the machine shutting down when connected to
the computer. You can format the machine or ask professionals to upgrade.
Q: Why does it shut down suddenly sometimes?
A:
- The shutdown time may be set in the “Scheduled shutdown” in the “Settings” option of the main interface.
- Please check whether the battery is low and need to be charged at this time.
Q: When the machine’s memory is larger than 4G, why does it prompt that the
disk capacity is full when copying a single file larger than 4GB?
A: Because the format of the disk is FAT32, it will prompt that the disk
capacity is full when copying a single file larger than 4GB. So when copying
files larger than 4GB, it requires formatting the disk to EXFAT .
Q: Why is the battery can not be fully charged when watching the video
while charging, or the video cannot be played when charging?
A： The direct reason is that the power of the charger used by the user is too
small, the output current can not meet the current required for normal
playback or can only meet the requirements of video playback and cannot be
charged at the same time. It is not a quality problem of the product itself.
It is recommended that MP4 users use at least a DC 5V-1000mA charger, and MP3
users use a DC 5V-500mA charger.
