so rather than preparation (which is obviously the first step to avoiding issues, ie, a UPS, back-up USB stick, etc) i'm looking for the quick-fix solutions that may resolve after an issue has arisen.
these are open to correction.
1) press RIG whilst powering up to clear damaged cache
2) use browse mode if performance mode is unavailable (this was what i had to do before i knew about the previous tip on one occasion)
3) plug into alternate input if your main input has been physically broken
4) use another output if similar to above
5) carry a PoE and spare ethernet cable in case the Kemper-remote cable has issues or gets damaged.
add to the list, anyone?
