The short answer is you can't. It's a unit deigned to connect to the audio lines and PTT of an existing mobile radio and allow use of that radio via a hand-held radio. Picture a state police officer making a traffic stop on a highway. Before he gets out of his patrol car he flips on the PAC/RT and walks back to have a chat with the motorist. His mobile radio hears a signal and that audio is transmitted by the 1/4 watt transmitter in the PAC-RT to the officer. He answers by pressing the PTT button on the handheld, and the PAC-RT receives the signal and keys the mobile TX. If a second patrol car arrives on the scene and enables his PAC-RT the first one is shut off. All of this is done on a simplex channel. A similar product can be found at <http://www.pyramidcomm.com/svr200.html> Read that web page for the theory of how it works. I've had a high band PAC-RT on the shelf for 10 years. I haven't found a use for it yet. It's based on a low-end walkie talkie, with the transmitter castrated back to one-quarter of a watt, with a very poor front end, and to change the frequency you need to order a new crystal and install it into a channel element. High band PAC-RTs were used on low band and UHF mobiles. UHF ones were used on high band and low band mobiles. A few ham radio operators here in the Los Angeles area played with them over a dozen years ago and while they did work, they were not practical in an area with a lot of repeaters... you might as well have the handheld talk to the repeater rather then talk to your car which talks to the repeater.
