Try turning the radio off.
Hold down the "F" key, the "Mon" key and turn on the power. You may
hear a series of beeps then release the keys.

I have a C510 and this is how the reset sequence goes for it and they
may be using the same CPU or programming for it.


I presume "F" is the function key.
I cannot find a "Mon" key on this rig. Is it labeled something else?



"Mon" key would be the one you push to "monitor". It either opens up
the squelch if you are on simplex, or checks the input frequency if you
are on a repeater split. On the C510 is right below the PTT button.
