Back up every important data in a memory card before firmware upgrade.
Save important files in the memory card in another storage device.
If recordings are not saved, or there are errors during operation frequently,
format the memory card. AW2 can format a memory card by itself.
(For more information, please refer to AW2 manual).
Memory cards are consumables. Regular checks and replacement are necessary.
AW2 works normally when firmware versions of Front and Rear devices are the same.
Do not shut down a car engine or detach the power jack before AW2 completes firmware upgrade.
Upgrade AW2 with the firmware COWON Systems, Inc. provides only.
