Beg to differ with your friend. Those small numbers are not sub-channels but rather are Interference Eliminator Codes. The represent what code is being used by the radio to eliminate other incoming transmission not with the same code (number). There could be similar radios working on the same channel/frequency, but if they do not have the same code then neither one would hear each other. This does not make a channel "private", rather it limits what one can hear on that channel to another radio with an identical setting of the code. In some Motorola models, pressing the Menu button until the small numbers/code flashes would enable them to be changed. To change, press the+ or - keys. Pressing the MON key or setting the code to Zero would enable the radio to receive and sound off all incoming signals with or without the code.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

I have two T5510 Motorola. Walkie talkies and when

Good job describing. The channel is the channel number, the upper right is the "tone". If everything matches, they should talk to each other. Try pressing the squelch button on each to make certain the speakers work. It is also possible the mic openings are clogged with debris or the audio jacks have something in them. If the audio jack has a broken pin or even debris in it, it is possible the speaker will remain muted. If you are using audio accessories, unplug them and turn the radio off/on. Do you have a tone on power up? Other than that, how old are they? Do you know the history? If they got wet, corrosion likely set in and you need new radios. Yes, I know some say waterproof, they mean resistant.

I have 4 motorola walkie talkies the channel numbers on one do not match the other three when they are on the same frequency how do i reset the one that is wrong

If they're not exactly the same model they may have different channel indexes. If the "oddball" is a combination FRS/GMRS or if the other 3 are, they'll have different numbering. As long as you can talk between all of them, just make note of the "right" numbers when they're working.

Hi Gary - I copied this from the RIO NIKE manual:

mode button
Press MODE to select the setting you want to change.
The normal display is replaced by the adjustable setting.
Use the + and - buttons to adjust the settings.
These are the settings you can change.
1. Main Channel (1-14)
2. Sub Channel (1-38)
3. Channel Scan (ON/OFF)
4. Sub Channel Scan (ON/OFF)
5. Button Confirmation Tone and Roger Beep ON/OFF)
6. Vox (OFF, ON LO, ON HI) (psc[communicate wxonly)
When you have proceeded through all adjustable settings, the normal display will reappear. Or, press TALK at any time to return to the normal display.

select main channel
There are 14 main channels.
To select main channels:
1. Press MODE until CHAN is displayed.
2. Press + and - keys to select the main channel.
select sub channel:
Each main channel has 38 sub channels, sometimes called
CTCSS channels. Select one of these sub channels to transmit
on a channel that is free from traffic.
To select sub channels:
1. Press MODE until SUB CHAN is displayed
2. Press + and - keys to select the sub channel.
Note :If you select channel "0," you will be able to receive transmissions from all the sub channels of the main channel you selected.

I have just bought binatone 750 they been charging for about 6 hours and are working. When on same channel we still cannot talk? help

Check your programming. Your frequency and (sub-channel) code both need to match on both radios. To operate in a simple mode, turn off the (sub-channel) code.
If you are using one of the common 8 frequencies and no sub-channel, you should be able to communicate. If you are still have difficulties post a follow-up question with more details and someone will try to assist you. OR call the toll-free number in the user guide for warranty assistance with the manufacturer.
Best regards.

No trasnsmission coming out of the speaker on one. 1 works ok and the other one doesn't

I don't know if the smaller ones like what you have operate the same as my 2 watt motorolas but I have a sub frequency on top of the channel. Check into that.

I can't get them to connect to each other

If the unit you are using is an FRS/GMRS radio then this might fix your issue.
  1. Make sure both radios are on the same channel, ie Channel 2.
  2. Now look at the screen on both radios...below the "2" is a smaller digit... this is a sub-channel.
  3. Are the sub-channels for both radios the same? If not they need to be matching. The easiest way is to set them to "0". (You can read more about the sub-channels in your Motoral owners manual if you have one.).
Here is how to change the sub-channel.
  1. Press the MENU button once and release it. You will notice that the main channel is now blinking.
  2. Now press the MENU button a 2nd time within 4 seconds to make the smaller sub-channel number begin blinking.
  3. Now use the "+" sign on he right (or up arrow), OR the "-" sign on the left (or down arrow) to adjust the sub-channel to the number of your choosing.
  4. Let's say you wan to set the sub-channel to "0". Using the above instruction in #3, do this and then immediately press the PTT (Push To Talk) button once to lock in your selection.
Both radios are now programmed to speak with each other on the same frequencies.
Your question did not have much detail, so I am assuming this is the issue. I hope this helps!

Motorola gp 68

Batlabs at (Hand Held Radios) has the GP-68 users guide(Operation Guide), on the right side I think what you might be asking is in "Basic Operation 2", if not look into the Programming section below it.

About motorola t5720

Hello, Thanks for requst me, As far as I understood, you have same settings in both radios, you mentined QT this is the 3° requirment to recive a signal, 1° channel, 2° subchannel (ctcss, pl, etc) and the 3° QT.
if you are using QT you must to send a Call from the other radio, I recomed to set the QT to Off in both radios and tray if you can communicate in both directions.
if does not receive, there is the possibility that one of your radios the Sub channel decoder is not working.
If you could test your radios with a Third radio to know wich radio is not working right.
Good luck
