The Motorola XPR 4550 is a two-way radio, not a scanner. Scanners are devices that can listen to a wide range of frequencies, whereas two-way radios are designed for communication between a limited number of specific devices on specific frequencies. However, you can use a scanner to listen to the frequency that the Motorola XPR 4550 is transmitting on.
It is a business band radio, not a consumer radio. It must be programmed by a Licensed Two Way radio shop. The radios are programmed by a dealer for whatever frequencies (channels) the customer requires, so each radio can be programmed differently.
1) are you within range,?
2) is there an obstruction between you and the repeater?
3) do you have the proper PL tome programmed for the repeater?
4) When you press transmit, is the correct input frequency displayed?
Both buttons have a short and a long press function. The button right below the PTT button is typically programmed to short press Monitor, long press Sticky Monitor. The bottom button comes from the factory on scan/nuisance channel delete. The buttons can be custom programmed when the dealer is programming the radio, so these are just a general guess based on the factory default setting. Other options include repeater talkaround, high/low power, volume set, and maybe tight loose squelch.
You need to reset your radio to factory default settings to be able to once again, use the radio. Your friend software will be required to do this, so... CHOP, CHOP, hop to it.
Uh, stick with analog. Digital radios do NOT have better range than analog. You lose about 5-10% on the outer fringes. For range, those radios were designed to operate on a repeater, often called trunked radio relay system.
Your digital radio is likely on someone elses' frequency. Channels are controlled by the FCC and are not for consumers. You must have an FCC License or an agreement to use the mentioned Trunked Relay. You may have a thing called busy lockout programmed, which means when someone else is talking, you get blocked. The only thing you can do to get your radio(s) working well is to have them reprogrammed by a professional (Radio Shop). If you can, have them programmed for analog only.
For basic radio use and reasonable coverage, get a couple of 25-50 watt Vhf analog radios. Get a License and you will be very happy! Buy the best antennas, installed correctly and you will have decent range. Antennas matter on terrain, so high gain may not be the best choice. Been a radio dealer/repair since 1980, before the start of digital and beyond. Beware the over promising of digital.
if all the channels are 000.000 then it wont scann youll have to hit manual then enter a freq then hit the "e" button. once you hit manual youll be able to push the up and down arrows to select an channel you wish to imput a feq. Hope this helps.
