I'm reaching out regarding the Portable X-ray unit I purchased from your company. I'm currently in need of a driver or operational software for this device as I haven't been able to locate it. Also, I tried contacting the number provided, but unfortunately, there's been no response. I'd really appreciate it if you could get back to me as soon as possible with the necessary information. Thank you!
