Kenwood: Kenwood TM-D710A question

[mobi1]

I have a Kenwood TM-D710A radio in my car.

I am unable to change its output power level.

I push the LOW button but nothing happens.

How can I change this?

See the attached image.

I have the 710 A right here in front of me. That is how it should work. Just press the "LOW" button repeatedly to cycle through the different power settings.

On my radio this does nothing.

How long have you had the radio in your car? If it's been a while you may need to see if you can open up the head and check the switch. It might be possible to clean it.
