Firmware Upgrade
The menu item will be enabled only if there is a memory card inserted.
When new firmware is released you can upload it to the device. Copy the new
firmware onto a memory card and insert the card into the memory card slot
[page 14, item 1].
Make sure that the firmware is the only file on the memory card and that it
hasn't been saved into a subfolder.
Tap the button
to proceed with the upgrade or tap
to cancel the process.
While the upgrade is running never remove the memory card and
do not power the device off otherwise the device may suffer
severe damage.
When new firmware is released you'll find it on our website
http://www.targa.co.uk.
If no compatible firmware I found on the memory card the
message Failed! appears on the display.
