Programming cp185 change frequency

Usually the dealer that sold them to you has to arrange for that to take place: https://www.motorolasolutions.com/en_us/products/two-way-radios/analog-business-radios/portable-radios/cp185.html#tabproductinfo

Yes, they must be programmed by a dealer to match your existing radios. Hopefully you purchased the same frequency band: VHF or UHF. I f they do not match that, they cannot be programmed to match. I don't know of a single 2 way dealer who would let those go out of their store without programming. Since you bought them elsewhere, another warning is they must be approved for the country you intend to use them in. You may be better off returning them and starting over. Many dealers, such as our store include programming at no cost when purchased from us. Call around to get some prices.

This is the model number for a UHF Motorola CP185. Specifically, 16-Channel, 4W Model 435-480 MHz. The only way to determine the frequencies programmed into the radio is to have the radio read-out by an authorized Motorola dealer or other entity with a subscription to the software, as well as, a radio interface box (RIB) and appropriate cable.

Best regards.

Could be one of several issues. A few which come to mind are:

1) You have a bad or poorly charged battery. Static is a sign of a bad or poorly charged battery. Try swapping a battery from another radio, with a known good battery and see if the problem is solve. If this resolves the issue check your battery and charger. Tip: Clean all charge contacts with a pencil eraser to ensure good charging. Also, check your 3- or 4-digit date code on the battery. If more than 2 years old, replace the battery. (4-digit date code example 1303 would be 2013 the 3rd week; on 3-digit date codes the first number is the year and the next two the week of the year.)

2) You are trying to use the radio in an area where you are experiences high RF on your frequency. This is the "busy"... someone/something is on or near your radio's frequency and interfering with transmission. Try your radio at a different location and see if the problem persists.

3) Another radio in the workgroup is stuck in transmit, causing static, and the channel busy. Turn off other radios, one at a time, and see if the problem still exists.

4) Or if you have an audio device plugged into the radio, try unplugging it and see if the problem stops. FYI: All audio devices must be plugged or unplugged with the radio shut off. If you plug one in with the radio turned on, you can experience some unexpected intermittent issues.

If none of these seem to be the problem, your radio is likely in need of repair.

Please post the model and Tanapa from the back of the radio so I can assist you further. I need that information to find the radio's bandsplit and whether it is narrowband and splinter frequency capable.

You can indeed adjust the frequency error on the CP185. You will need a very small (preferably ceramic, but you could get by with any) screwdriver. Use some alligator clips to power on the radio with the battery not attached to the back, and peel back the small circular metal sticker. Under it you will find a very sensitive potentiometer which you can adjust with your screwdriver, while transmitting, to fix the frequency error.

Hi christo,

Yes the serial No. usually indicates the frequency band the radio works on, but not always, because a lot of radios nowadays can operate on both VHF & UHF, so not being familiar with your model, I can't give you a definitive answer.

I do have the feeling, for what it's worth, that it is in fact a UHF band radio, but don't take that as gospel.

Anyone else reading this post is most welcome to assist in helping a friend out, we would much appreciate your input, thanks.

Hang in there my friend, there will be an answer soon.

Cheers, Peter

I'll look into it further as well....

The CP185 is dealer programmable for up to 16 channels. You would need to see an authorized Motorola dealer to have the radio reprogrammed to your additional FCC assigned frequencies.

Best regards.

Could be a variety of problems. Common issues might include a bad or poorly charged battery, an unprogrammed channel is selected, or you are programmed for busy channel lock out, and their is local traffic on your frequency causing you to be blocked out.

To test your battery, try trading with another radio which has a known good battery.

Check with your local dealer or a repair facility for more help.

Best regards.
