Sounds like you do not have your radios programmed to match one another. The MU21CV is a user programmable model. You might call your local Motorola dealer or one of the companies online to have someone walk you through programming the radio(s). With this model it can appear the radio is not powering up, when it simply is not programmed correctly.

SOURCE: when i try to talk

Two things come to mind. First, you may have a bad battery. It is typical for a bad battery to cause the radio to have static, or poor transmit. Second, you may not have the radios set to the same frequency as one another, or one is on a narrowband frequency, and the other is wideband. (Depending on the age of the two units.)

Try switching the batteries between a working radio and the staticy radio. See if the problem moves to the other radio. If so, replace your batteries.

Check your programming, if you don't know how, contact your local Motorola dealer or give us a call (google our name). We can walk you through programming over the phone.

Lastly, if all these suggestions fail, your radio may be in need of repair. Flat rate repair is currently around $69 ea.

Best regards.

What motorola radios are compatible with mu21cv, mu22cv and mu24cv


Any Uhf Motorola business radio can be programmed to match. None of the toy radios will ever work. (GMRS/FRS)
Easiest to self program will be the the XTN, also called CP100, and RD (RDU) and even older Spirit and SP10 are possible, but harder. RD's are really hard without the programming cable, available from a dealer.

Will the MU21CV radio's work with the talk about radios?


Short answer, maybe. It depends on whether you have a 14 channel or a 30 channel Talk-About. The Motorola Talk-Abouts operate on the FRS frequencies (14 channel) or FRS & GMRS frequencies (30 channel). The MU21CV does cover a few of the GMRS frequencies. (see bold numbers)

GMRS Frequencies
462.500, 462.575, 462.600, 462.625, 462.650, 462.675, 462.700, 462.725, 467.550, 467.575, 467.600, 467.625, 467.650, 467.675, 467.700 & 467.725

FRS Frequencies
462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, 462.7125, 467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, 467.7125

Transmit button on the lapel mic will not key the radio


Two things which come to mind, one would be if the PTT on the remote mic is bad/defective, second would be you are plugging the audio device in with the radio turned on.

If your remote mic is failing, the PTT is a repairable item, as is the cord on most models.

Hi,

The problem of failing to power on can be caused by:
1. dead battery (may no longer hold a charge);
2. corroded battery terminals or connectors;
3. open wiring from the battery casing to the internal circuitry;
4. defective on/off switch; and/or
5. defective regulator component(s) on the main PCB.

On the other hand, problem on receive can be caused by:
a. defective or worn out volume control (if manual/rotary);
b. defective or worn out squelch control (if manual/rotary);
c. mismatch in PL or CTCSS code; and/or
d. defective internal speaker.

Most can be checked with the use of a continuity tester or a DVM. Repairs involve knowledge and familiarity with electronic components and circuitry and perhaps even the use of a soldering iron. Should you not be comfortable doing it yourself, perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of help. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
