You need to have the programming software and cable. It is an older radio and I do not think it is Narrowband capable, meaning you cannot legally transmit in the USA.
You may not be able to. If you have the programming software and cable look for the W/N option for each channel. I don't think the EPH is NB compatible.

Hi,Bendix, at one time was a good brand, however, this isn't so these days, as these are manufactured to a standard of dubious quality.The query you have posted doesn't make sense.Do you want to know what frequency range these radios will work on?If so, can anyone reading this post help a friend out?Cheers,Peter
