My Motorolla GP 68 changes to a differant freq. when the PTT is pressed?

This is usually a low battery issue. If you are using the rechargeable battery pack, does your Motorola unit accept regular batteries in place of the rechargeable battery? If you can put in 3 or 4 AA batteries (depending on the model), try that. If the radio stays on when you press the PTT button, then continue using the regular batteries or get a replacement rechargeable battery, if you can find one for the model. If the radio still turns off when you press the PTT button with fresh batteries, then replace the two-way radio.

I hope this helps. When the rechargeable batteries fail, they will still charge but they won't hold a full charge for as long a period.

The MU21CV radio is user programmable. Hold in the PTT button while turning on the radio. It will announce the frequency. Use the PTT button to count it up to the frequency you desire. Press the smaller monitor button to lock in your freq. Then the radio will announce the code number. Once again using the PTT button count it up to your desired code or the word OFF if you are not wanting a code. Then press the monitor button to lock in the code. At this point you can turn off the radio and turn it back on normally (without holding in the PTT). Your radios should be programmed to match one another. If you are still having trouble you may have a radio which needs repair or a bad/low battery.

The CTCSS codes are probably not set correctly. Baofeng manuals are notoriously hard to read. Look online (Google) alternative programming instructions.

Here is a link to the user guide, the instructions for getting into programming mode begin on page 18: http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/XTN_Series_User_Manual_E.pdf

A synopsis:
1) Hold in the PTT button and MON button while turning on the radio.
2) Press the MENU button one time. This will display your freq in the upper right. Use the plus or minus buttons to change the number. Press the menu button to lock in your slection.
3) The next number is your Code. Use the same method to select your code and lock it in.
4) Continue through the menu, pressing one at a time, making your selections according to the user guide. When you are at the end of programming you will hear a different chirp. When this occurs, shut off the radio and turn it back on normally. You are done.

Hold in the PTT button while you turn on the radio. It will announce the frequency number. You can use the PTT button to change the number. Then press the Monitor (small possibly red) button to lock in your setting. The next number your radio announces will be the Code. Use the same method to change the code if needed. Then press the Monitor button to lock in your setting. Once you have set both your freq and code you can turn the radio off, then turn back on normally and use the radios.

Best regards.

Hold the PTT button and the MON button in while turning on the radio. Continue to hold them until the programming initialization noises stop. Press the menu button one time to get to the Freq setting, change it to 6. Then press the menu button to lock in this setting. The next menu screen is the Code, set it to match your other units. Then press the menu button again to lock it in. Press the menu button to walk through another 2 or 3 screens and then you will hear a different chirp. Your radio is now programmed, simply shut it off and turn it back on and your radios should work.

Best regards.

I don't think that you could program/change the freq of your Motorola GP2000 manually since newer Motorola radios today everything is done by computer and programming sotfware. You need to have software for GP2000, radio interface box ( RIB) and programming cable for GP2000 radio and these devices are not cheap. The best way is to contact a local repair shop to have it done for you or find a two-way radio technician, he could do this if he has all the test equipments required.
Good luck!

With the radio turned off, hold in the PTT and the Monitor button at the same time. Continue to hold these in while turning the radio on. Wait for the radio to finish making sounds before releasing the PTT and monitor button. Then simply press the menu button to walk through programming each of the features. When you have reached the end of the user programmable features you will notice the radio has a different chirp to signal you are done. Then simply turn off the radio to leave programming mode.
