| I check the charge on the unit 2 or 3 times a year and check for firmware updates. The rest of the time it sits in the hard case, in a desk drawer. This maintenance period, the unit I got 8/25/2024 charged via USB just fine, but when I attempt to power the unit on, it only stays on if I keep the button depressed. If I release the button, the circuit is broken immediately. Any ideas other than buy a new one? |
