Re: JRC 1000 Radar won't power on??
I have got one.
When first powered up, it takes about 90 seconds before the display will show the sweep.
There is a count-down in the centre of the screen.
I cannot remember if it beeps when I first power up. I suspect it does.
Check the power supply. Make sure you are feeding enough volts. Start your engine to improve the voltage supply, if necessary.
