Typically this would indicate a battery problem. Try swapping batteries with a known good unit. If the radio still shuts off when the PTT is pressed you have a radio problem. If it works fine, then you know your battery, despite showing fully charged, is bad.

SOURCE: Radio cuts out (screen goes blank) when you press "talk" button

You are correct, the battery is bad. When batteries begin to fail, they may appear to hold a full charge, but when put under a load they fail to maintain the proper power to fully power the radio. Generally you will notice screens going blank, poor or no transmit, etc. Simple solution, replace the battery. New batteries are available for around $30 (US dollars).

SOURCE: motorola t7 - 1 unit has receive indicator

Hold in the PTT and the monitor button while turning on the radio (wait for the sounds to stop) will put you into programming mode. You can then use the menu button and the +/- buttons to walk you through the settings. Using this menu, you can program your radio to match your other unit.

To read out your master radio, put it in programming mode, and simply press the menu button to walk through the settings. Do not press the +/- along the way, as it would change a setting. Once your have your master radio read-out, you can proceed with programming the one you are having a problem with.

Best regards.

Your battery may be fully charged but defective. To test try swapping the battery from a known good unit into the radio and see if you have the same problem. Check your battery contacts, and clean with a pencil eraser if needed. If these do not solve the problem, your radio is likely bad.

Ptt cant go through

It is possible you have a battery or charging problem. Transmitting takes more energy than any other function of the radio. Pressing the PTT can quickly reveal a bad or poorly charged battery pack. Check your charger, clean all battery contacts on the charger and radio with a pencil eraser and try charging again. Also, you can try changing a battery out of a known good unit and see if the problem moves with the battery.

Motorola talkabout MJ270R switching off when transmitting

Turning off while transmitting is typically a sign of a weak or bad battery. However, since you mention it happens with either battery type, another cause might be the length of time you are depressing the PTT button. These radios have a fail-safe to prevent damaging the final amplifier of the radio. To protect itself the radio will shut down or stop transmitting after the PTT button is held in too long. This being said, I'd check the batteries first. The rechargeable battery pack which came with the radio has a one year life expectancy. A battery can test full when it is weak and might not hold the charge when placed under a load. And usually transmit is the first thing to fail.

Generally when a radio shuts off when you press the PTT button it is a sign of a bad or poorly charged battery. It takes more energy to transmit than to receive. The fact you have a charge which the light does not come on indicates you have a bad charger or bad connection between the radio and/or battery and the charger. Clean your battery contacts (on both radio and charger) with a pencil eraser and see if it clears up the problem. If not, you have either a battery or charger problem.

First, make sure the battery is fully charged and red LED TX indicator is on steady as long as you are holding the PTT button. If the red LED blinks while you are transmitting, the battery is not charged, or is bad.
Otherwise here are some common problems with the SP50 that can cause that issue:
Bad PTT switch
Internal microphone is bad
Speaker/microphone is bad-if used
Jacks are bad
Transmitter power amplifier is bad
Antenna is bad

Contact a local dealer for proper diagnosis.

Your batteries are either no good, or not charged. When you press the PTT button it takes more energy than being in standby mode. If you have a battery problem it will fail quickly when the PTT is pressed.

Rechargeable batteries last approx. 18-24 months. Check your battery for a 3-digit date code. It is usually a 3 digit number followed by a couple of letters. The numbers tell the date of manufacture. The first number is the year, followed by the week of the year. 025 would be 2010 the 25th week. (or if very old it could be 2000 the 25th week.)

If you feel age is not a problem, you might check your charger(s) to see they are fully powered, and clear of debris on the contacts (and the radio contacts as well). Clean with a pencil eraser if needed.

A few tips: Be certain when placing your radios on the charge they are turned off. Check your wall outlet to be certain it doesn't get shut off with a light switch. Expect to replace your batteries every 2-3 years.

Best regards.

I have a motorola AXU4100 radio. Every time I use it to talk it shuts off.

It is likely your battery pack is not fully charged or it is in need of a new battery. It takes more energy to transmit than to receive. Pressing the PTT uses quite a bit of power and will easily shut down a radio needing a battery (or charge). If you feel you battery is still good (less than 2 years old), you might check your charger to see if it is functioning correctly.

Best regards.

It automatically turn off when press the PTT button.

This is usually a power problem - if the transmitter cannot draw enough power to operate, it shuts the radio off to prevent circuitry damage. Make sure that you're using fresh, fully charged batteries, and that the contacts on the batteries and inside the radio are clean and free of corrosion.
