UPDATE PROCEDURE

1. Backup your SD Card by removing it from the metron and copying its contents to your computer.
2. Extract "UPDATE.BIN" from the zip file.
3. Place "UPDATE.BIN" in the root directory of your Metron sd card. Replace the file if an older one is present.
4. While Metron is powered down, place the sd card back into Metron.
5. Connect Volteras if necessary.
6. Power Metron on. The screen will read "BOOTLOADER", and an animation will play.
7. Wait until Metron fully boots to it's normal operating screen before powering down, removing SD card or playing.
8. Volteras will cycle their LEDs, showing progress in Yellow. 
       - A fully updated Voltera will have all Voltage LEDs off and a dim "select" LED.
9. Axxent will blink it's button, showing update progress. 
       - A fully updated Axxent will have a solid dim "select" LED.
