My #1 radio defaults to the emergency freq whenever it is turned off - my number 2 does not it stays on the last freq used. I am told it is because the internal battery is no good. I saw in the manual it was a lithium battery but it doesnt give any other info.
Does anyone know the part number for the Lithium battery in a MX 170B radio?

Thanks
