I having a set of 3. And 1 of them having problem to transmit to 2 set, under the same frequency and channels. This faulty set beep 2 times, after I push down the PPT. The other 2 working set will not have such beeping sound, and they are able to transmit to each.
Why is the talkie reacting these way? It is really time for servicing?

Re: Motorola EM1000 2 way talkie unable to transmit
Low/Bad battery beep most likely. Try switching batteries to the problem radio and see if the problem goes away. If so, replace the batteries. You might also check the battery contacts both in/on the radio and the battery. Clean with a pencil eraser if necessary.

"Mon" is short for "Monitor" and is usually a feature that allows you to momentarily break the squelch (signal filter) and hear anything being transmitted on that frequency. That includes static if there's no transmissions. It allows you to listen for a weak signal that can't break the squelch threshold you have set. Some radios allow you to lock it open by pressing and holding the MON button for a few seconds. Turn the feature off my doing the same thing.
Check your Code setting. Both the frequency and the code must be identical for the units to communicate. Shut off any special features and keep the radios at a simple setting until you get communications back.
Double check the frequency you have the radios set to, and be certain they are exact. Sometimes when you are on a near frequency you will have range problems. Also, hold the radio upright with the antenna pointed straight up when transmitting. Face the direction you are trying to transmit. Height and placement of the antenna determines range. Handhelds can generally talk as far as they can see. Obstacles between you and the other radio can reduce range, including the body fluid of the person wearing the radio. And lastly, be certain you are using good batteries for best performance.
This unit does not have a reset button. While troubleshooting you might check the batteries. Be certain they are in correctly and the contacts are free of corrosion. You can use a pencil eraser to clean the contacts.
Walk through all the programming instructions in the manual, double checking both the frequency and interference eliminator codes. A quick setting back to zero on the code would alleviate any problem with that section of the radio.
As far as your "paging" this operates on the same frequency and code as the rest of the radio. If the radios are not working correctly in this relm, the paging will not work either.
Most Motorola radios give a beep-beep when the batteries are low and need changing. Make sure to use a good brand of battery. One other thing to check for is leaking batteries, the crud with cut down on performance.
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.
Here is a link to the T5000-T5500 user manual. 'http://www.motorola.com/mdirect/manuals/T50-T55_UserGuide.pdf'
From what you have stated, I can discern the radios will power up. You might try setting your interference eliminators to zero (off) to see if you are able to transmit at all.
You do not mention if you are using AA batteries or rechargeables. Either way a fresh set of charged batteries would be best for a test. It is clear you were getting power. However, it does take more energy to transmit than to receive. If your batteries are low or bad, pressing the PTT could us all the energy the radio has, and yet not transmit to the other units.
You might also check you VOX settings if any and be certain they are turned off.
It is not likely 4 radios would fail all at the same time. So it is probably a programming problem. Hope the user manual helps you find the solution.
