The device works, but it gives equipment disabled therapy failure. In my research, I came to the conclusion that there may not be a serial number, but the serial number is written in the device information. can you help me solve this error? RE: Philips - Hearstart XL+
I have a unit that won’t power on either on wall power or battery. It gives a few beeps with a quick screen flash and nothing. Else happens. It will continue to do that until it’s turned off or unplugged. Any suggestions? RE: Zoll - E Series
Hello! I am having strange issues with my GE Mac 5500. When the unit is unplugged and running off battery, the display works perfectly fine. However, as soon as I plug into AC power, the display shuts off and does not come on. I have never seen this happen and wanted to see if anyone has seen this issue, or if you have any troubleshooting advice. Thank you!
