Technical Support / Re: Voltage error message on iphone
« on: September 17, 2023, 06:39:12 pm »I’m using Rosetta. The following in the USB ports : dongle, GPS, aircrew, and Wi-Fi. The PAW is powered from the 12 volt cigarette lighter using an Anker QC adapter. Even with the voltage error message on the iPhone the radar screen seems to be giving me all the info it’s supposed to and generally works very well
With all due respect, the "it is working so what is the problem?" approach has a slight flaw in the logic.
When the voltage is low, the processor may throttle itself in terms of processing speed/power and whilst things will work, they will not necessarily work how they are meant to.
The voltage alarm is most likely caused by the Aircrew device, if it is powered via its USB port, unplug it and the problem will probably go away.
If you need a data link to the Aircrew device to display traffic, then see if you can power the device directly with 12V in and just use the USB for data input.
There is a 12V input on the back.
I think you'll find elsewhere on this forum that people have been advise against powering Aircrew from a PAW...
Lee can give you precise details about how much throttling affects the PAW, but if you continue to use it whilst throttled you are asking for other problems to arise at some point.
