Batboard

Hi there! I just picked up a pair of Motorola Radius SP-50's.... Only problem is that they didn't come with a manual, and I can't find a copy of it on the internet. Could someone please tell me what the two buttons on the front of the radio are, and how to operate them? One of the button says "MON" and the other says "OPT".

Thanks!

the mon button puts the radio into monitor mode, and the opt button is used to toggle between high/low power, scan/nusaince delete, squelch or none. the function of the opt button is programmed in by computer
