5 Firmware upgrade
Improper operations during firmware update may cause the M3K to malfunction! Please read the following
firmware update guide carefully before proceeding.
Update procedures:
Please go to our website to download firmware. Download link: http://www.fiio.net/en/supports; copy the
M3K.fw to the root directory of an FAT32-formatted SD card.
2. Turn off the M3K and insert the card into the slot on M3K (if not already inserted).
3. Hold the "Volume up" button and then also hold the "Power/Lock" button to turn on the M3K in firmware
update mode. The following firmware update dialogs will appear:
Unzip Package...

Update Successfully
Before proceeding:
1. Choose a micro SD card with FAT32 file system. If update fails, try using a card of 32GB capacity or under,
format it using the M3K (back up data on the card first), copy M3K.fw inside again and attempt upgrade again.
2. Firmware update will not affect files stored on the card.
3. Ensure M3K is sufficiently charged (preferably fully charged) before the update to prevent power failure
during the update.
4. Do not operate the M3K while the update is in progress.
5. Please delete the M3K.fw file after the firmware update.
6. Please update the media library after the firmware update.
6 Notes and precautions
★
M3K will skip any songs it has trouble in decoding to prevent hang-up.
★
If the voltage from the charging adapter is too high, the M3K may be damaged. Please choose an
appropriate charger; a DC 5V/2A USB charging adapter is recommended.
★
In the likely event that the M3K hangs up, you may hold the power button for 10 seconds to force a
shutdown.
★
You need to first update M3K's media library before using the function of "Play by category" and "Play all".
★
Please charge the battery on a regular basis to secure the battery life if it's to be left unused for a long time.
Batteries should not be exposed to direct sunlight, fire or other such high-temperature conditions.
