2. What should I do if the M15S crashes or freezes?
Follow the measures below to see if it can help if the M15S crashes or freezes:
1.【Force to reboot】
Please hold the power button for around 10 seconds until the ""FiiO"" logo shows up.
2.【Extract a LOG file】
For special software issues, please extract a LOG file under the root directory, unzip and copy it to the homepage. And then send it to us for analysis.
Please go to " Settings ->About device" , and continually tap “Model number", until the prompt "Have save output log to built-in storage" appears.
Then please wait for about 20 seconds, and go to M15S's internal storage, then send the folder "fiio_log " to us and inform us the time of the problem for further analysis.
3.【Fail to be charged or turned on】
a. Hold the power button for about 10 seconds when it is charging
b.Try other power adapters and charging cables.
c.The battery of your device may be overused, so it needs to be refreshed through low-current power. It is suggested to charge it through the computer for more than 2 hours, and then unplug the charging cable to see whether it can be turned on.
d. If the problem still exists, please try to leave the device aside for 2 to 3 days, and then charge it again. Because sometimes its system may be stuck, it would return to normal when the device runs out of power.
If the above measures can not help, please ask the local seller for help or contact us by sending an email to email@example.com.
4. What can be done if I forget my password?
