I keep getting a message saying "firmware update failed. Cycle power to Synscan and try again!"
I turn the power off and on again but continue to get the same message.
I have the handset plugged in via the same battery I use on site.
Could this be due to low battery charge or because the handset needs to be updated via a power source other than a 12volt battery?
Any help greatly appreciated, as presently there seems to be no firmware on the handset.
cheers!
