    The cp200 is old if i am not mistaken. Where did you get it? What are you using it for? Was it damaged? So many things could be wrong with it. The speaker could be bust, the rubber duck could be broken. I really need more than its just nosie.

It is possible your radio is not programmed, or has a bad/old battery.

It is normal for the side buttons 1 and 2 to beep when depressed to indicate you turned the feature on/off. Each of these buttons has the ability to be programmed a long and a short press feature.

If your radio beeps when your press the PTT button, on any or all channels, it indicates a low or nearly dead battery. Check your battery date code to see if the battery needs replaced.

If your radio emits a long tone on a channel, that channel is not programmed to function.

If your radio beeps a single beep when you turn it on, this is normal.

Charge your radio completely overnight, with the radio turned off. See if this solves the problem. If not, try a new/different battery to see if it will solve the issue. If not, drop by your local dealer and let them look at the unit.

I have a CP200 that beeps twice at regular intervals, and seek to correct this. It transmits and all, but the beeping is irritating.Suggestions?

It really sounds like a low battery alert. Swap batteries and check the date codes. How long off the charger until you get the beeping? Lithium batteries do not last as long (lifetime) as the older types. Motorola uses 4 numbers, year followed by the week such as 1344 = 2013, 44th week. Chargers are just that and do not test a battery. If the problem persists I have something else, but it is not easy.

Cp200 squeel

This is called feedback. The audio output from the other radio is feeding back through your microphone. Turn the volume down on the radio at a comfortable listening level, and do not transmit when in close proximity. If they can hear you speak, you do not need to transmit.

HEllo, I have a Motorola Radius CP200. When I

If the sound is continuous, like a long tone humming, it is possible you are on a channel which is not programmed. Try changing your channel knob to a different channel and see if the sound changes.

If the sound is not continous, and only happens upon pressing a button, we are not certain what you are experiencing without seeing the radio first hand.

If it were the battery you would get a low battery beep and then the radio would shut itself down. This can happen from a bad battery or a low battery. If this were the situation, you should check your charger and be certain the light comes on and stays on when the radio is placed on the charger. (Note: your radio should always be turned off when on the charger.) A quick test would be to swap the battery with a known good radio and see if you have the same problem. If so, you know it is not a battery or charging problem.

If none of these items help, send or bring the radio to a Motorola repair shop for a quick analysis.

Best regards.

How to change freguency on motorola

1) Put your radio in programming mode by turning on the radio while holding down the PTT and MON buttons. Continue to hold these buttons until the 'noise' stops.

2) Press the MENU button once. Now, using the + or - buttons choose the frequency number.

3) Press the MENU button to lock in your frequency. This will take you to your CODE. Press the + or - button to choose your CODE.

4) Press your MENU button to lock in your CODE.

5) At this point you can walk through the rest of programming features or simply shut the radio off and begin using it. Note: You will know when you are at the end of the programmable features because it will chirp a different beep than you have been hearing when you've pressed the MENU button to lock in your new setting.

Here's a link to the CP100 (sister radio) manual for more info:

Question about motorola cp040

The CP040 is a sister to the US version CP200. These features (roger beep and Tx power) are done during the programming of the radio using Motorola CPS software, a radio interface box (RIB) and appropriate cable. The software is proprietary to Motorola and is available by subscription to Authorized Motorola dealers and other qualifying entities. You can stop by your local Motorola shop to have the radio reprogrammed. (approx. $15-25 US)

Radius CP200 is in monitor mode I think and i can't get it out of that mode by pushing the programable buttons

Your programmable buttons can be programmed to a number of options. Typically the first button is programmed to monitor and sticky monitor. If this button has been held in a long press you can clear the setting by holding it in another long press to shut it off, or by simply shutting the radio off and turning it back on.

Your second programmable button could be set for an number of features, but like the above description, simply pressing it again or shutting off the radio will turn the feature off.

When you refer to Monitor Mode, we assume your are indicating the radio is operating open squelch, with no private line code. This is when you can hear ALL transmissions on your frequency. If this does not describe the problem you are having please repost another question.
