Disassembling my Lab599 Discovery TX-500 radio to check my memory retention battery.
Was using my TX-500 at a friends cabin doing SSB when another QRP radios microphone fell on the TX-500 causing the screen to become distorted and upon rebooting completely blank! I panicked and emailed US support which asked me to check the coin battery. Luckily there was no damage to the radio and was easy to check.
I hope this video helps those out with this radio in the event this issue happens to them.
