I'm trying to find out how to use them i got two Motorola Talkabout T5100 from a yard sale i got both on same channel i push talk and nothing


As a basic test, if you press the transmit button on one, you should hear some sort of response from the other. I suspect your T5100s are defective.

I have a uniden bearcat 880 CB radio and just hooked it up to a K40 antenna with a 9' mini 8 coax and for some reason my swr is pretty much 3 and it passes on the rf output test but fails antenna test


Failing either test is odd. Is mini 8 coax RG 8x? I assume it is, so your readings do not make sense. My first suggestion is to test with another piece of coax. If it tests fine, check your connectors! If it is still bad, you may have a rare piece of bad coax. It happens, just not often. Please post your results. Jack

My Motorola mr350 2 way radios are brand new but just stopped communicating. I cannot hear or talk using any of them. Don't know how to fix it


Try reprogramming your radios back to a very basic mode with all the special features turned off (or set to zero), including the interference eliminator code, Qt filter (if any), and call alerts, etc. Make certain your frequency matches on both radios. The radios should communicate easily in this configuration. If not, since they are new radios, contact Motorola using the number your user guide and talk to them about warranty replacement.
Best regards.

2005 Chevy Malibu Classic. Car will not start. Passlock has already been disabled. The Radio, AC temperature, fuel indicator and alarm does not work. It comes on and off at random times. The trunk pops...


What aftermarket stuff have you had installed ? any ? Radio etc.....
What alarm does not work ? Content theft ? How is pass lock disabled ? AC temperature ????? Do you own a factory or professional grade scan tool ? Will all the modules on the vehicle communicate with the scan tool ? GM had a problem with instrument clusters ,step motors ! That could be your fuel gauge problem , plus the solder they used , have you heard of silver migration .Just guessing as to a problem never fixed anything , that's all anyone on here would be doing , guessing . Testing electrical circuits ,power an grounds . Loaded circuit voltage testing, voltage drop testing etc.. Do you know how to do automotive electrical testing , how to read an use a wiring diagram to pin point test areas . Do you know what C.A.N. is controller area network , a serial data ,communication network for the modules on the vehicle . How to Diagnose Controller Area Network CAN
How to repair GM Instrument Cluster Speedometer Gauge Stepper

You have no idea of the complexity of the electronics on your vehicle , The BCM , radio , HVAC , Instrument cluster , ABS , PCM/ECM , SRS , an others are all hooked to to the data bus ,or network , all it takes is one module to act up to bring the whole system down , causing no start problems ! Hooking up a scan tool is the first step .

You need to clean NVRAM on Lexmark X5470 printer. Please follow the steps given below to clear NVRAM on Lexmark X5470 printer:

1. Turn the printer off.
2. Hold down "#5" button and turn the printer back on.
3. Keep holding "#5" button for about 5-10 seconds.
4. Press "Menu" button once.
5. Press the right arrow until display shows "Tools."
6. Press "Check" button once.
7. Press the "Right" arrow button again until display shows "Maintenance."
8. Press "Check" button again.
9. Press the "Right" arrow button again until display shows "Manufacturing."
10. Press "Check" button again.
11. Press "Right" arrow until display shows "Clean NVRAM."
12. Press "Check" button to clear nvram.

Next, try this printer self-test by following the steps given below:

1. Make sure the printer is in “Copy Mode.”
2. Press the “Menu” button once.
3. The screen will display “Copy Menu: Copies”.
4. Press the left arrow button once. The screen will display “Copy Menu: Tools”.
5. Press the check button once. The screen with read “Tools: Maintenance”.
6. Press the check button once. The screen with read “Maintenance: Ink Levels”.
7. Press the right arrow button until the screen reads “Maintenance: Print Test Page”.
8. Press the check button once. This will start the Self-Test. Once the page has printed, the printer will stop. The test is not continuous.

The self-test should at least print out a set of either a solid black or solid color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, please try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with only a color cartridge installed (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed). If you find that either cartridge causes the self-test to fail, please let us know.

If the self-test prints, but has lines or smudges or other print quality issues, please let us know. This includes any print quality issues - we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.

If the self-test prints your test bar(s) clearly, the printer hardware is not at fault.

Motorola T5420 Transmit Problem


Here are some troubleshooting thoughts:

1. Is your battery indicator showing at least 2-3 bars? (Battery Note: Your rechargeable batteries may fail due to setting without use for a long period of time. They need replaced every 12-14 months usually. A good tip is to charge them once a month to keep the chemical in the battery active.)

2. Check to see your Qt noise filter is shut off. Refer to page 22 of the owners manual. It is possible you have some radios set to Y and others to N. To assure good communications you should set all of them to N.

3. With your radios set to interference code zero, place your radios one at a time in scan mode, while you transmit/talk on one individual radio. See if any of the radios receive. Do this with each radio individually to see if you are transmitting at all. NOTE: This test will determine if you have any ability to transmit. If you do not receive any sound on the 3 radios setting in scan mode, the individual radio you are testing will not transmit.

Did the radios previously work together? If so, you have one radio in need of repair.

If the radios are new to you, and you do not know if they previously worked together, it could be a simple programming problem. Take it to your local Motorola dealer to check the programming.

One simple test to see if you have one with PL and one CSQ, is to press the monitor button and see if the two radios can communicate when they are in open squelch mode. (The monitor button will be one of the side buttons near the PTT.)

Talkabouts not communicating


What you have described is typical of the radios not being on the same frequency and/or code. If you know how to put your radios in programming mode, set all the frequencies and codes to the same number, then they will work together. If you still have the owners manual it will describe this process. Usually with a TalkAbout radio it consists of holding in the PTT while turning the radio on.
As you are probably aware, the radio will have approx. 14 frequencies installed. You can usually select these easily from the front panel. The second number you see in the corner of the screen when you turn on the radio is the "code". This is an interference eliminator. All of your radios need to be set to the same code to work correctly together. If you find one or more of your radios does not have "code", simply set those that have "code" to zero.
