Hello Bill

Thanks for the reply, it doesnt look like the radios are intrinsically safe from your description although they are fire radios and have the badges on them and the London fire brigade badges at the top.

I have 1 screw in the back and the tray pulls out, any ideas how I open it to put eh crystals in and check the PCB? we also may be related somewhere along the line as my name is also Knox as well.

Cheers

Paul Knox
