For the POD HD500, POD HD (bean) and POD HD Pro
Power Up and Nav Pad Right = TEST mode and Safe Mode - used to test button and expression pedal functionality as well as to recalibrate the expression pedal. You can avoid some flash memory update issues by updating in this mode
Power Up and Nav Pad Down = direct access to Flash Memory update mode - good if you need to update your flash memory and cannot access update mode in any other way
Power Up and Nav Pad Left = Global Parameters Reset - can get you out of a start-reboot loop if the patch you last used is corrupted because it defaults back to Set List 1 Best of HD 1A Son of Plexi - if you use this with the POD HD500 you will need to recalibrate the expression pedal and rename Set Lists 5-8 back to whatever they were named prior to resetting the Global Parameters
