GMC 600+ I purchased in May 2023 and have used a few times. Been working fine so far. It's been sitting in my closet in the case and I just took it out to test a new piece of uranium glass I bought.
When I turn the unit on, it instantly gives a constant beep (as well as a secondary beep noise). Light stays solid red. Also begins malfunctioning by showing an insanely high reading. Toggling the alarm off or trying to do a factory reset did nothing and it would appear that it's not accepting any inputs either.
Battery showing full charge. No damage to unit. Any ideas or should I call for warranty support? Thanks
What if you take out the battery and try powering it with only a USB cable plugged in? If that fixes your issue then it should be an issue with the battery. If that doesn't fix it, then it's something else.
