I have a used P10 and it does not have the variable Multiwave (1 to 6) or the phase setting in the setup screen. Also at reboot the initialization screen is not active or can not be selected/touched to get the latest firmware. Can I reflash this unit to the latest firmware? V0.46? Or is it not compatible?
You should be able to update to .46 without any problem. Just make sure you have an SD card that is 2Gb or less. The updates don’t have to be sequential.
