************** VERSION 4.15 ****************
This firmware upgrade is for use with the Spider 2

It is compatible with FSP-202 software

Extract the ".tar" firmware files from the zip file and copy them onto a laptop or PC connected to the Spider 2.

Log in to the unit then go to the About page and note your unit's current software version, e.g. "FSP-202 4.12".

Go into Change Setup and navigate to Upgrade Software.  Click the "Choose File" button and browse to then select the ".tar" file matching the current software version.
For example, if your unit is currently running "FSP-202 4.12" software and you are upgrading to 4.15, you would select the "FSP-202_spider_4.12-to-4.15_locked.tar" file.

Click Open then "Upgrade".  A warning will pop up asking whether you want to proceed.  Click "OK".
At this point the upgrade file is loading.  There is no need to exit the page or click anything.  When the file has loaded, the upgrade page will exit back to Change Setup and the upgrade will proceed in the background.  After a couple of minutes the LCD will display "Reloading" and the unit will boot with the new firmware.
