I recently got a Motorola CDM1550 LS+ It has the frequency I need all ready programed into it... but the tone is wrong. Can I change the tone from the face of the radio without needing the software to do it. I know nothing about these radios. Thanks for any help you can provide. Also if there is a radio shop I can send it to that will work as well. I don't know of one in my area. Willing to ship it, if needed.
