    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

APX Maintenance Mode Remote Device

Dear Forum Members,

We are currently experiencing an issue with some of our APX 2500 P25 mobile radios. Suddenly, these radios display the message "Maintenance Mode Remote Device" and have stopped functioning properly.

Could anyone kindly assist us in resolving this issue? Any guidance on how to exit maintenance mode or troubleshoot this problem would be greatly appreciated.

Also I am looking for assistance regarding the software configuration of our APX 2500 P25 mobile radios. We need to change the Radio ID so that when one device calls another, the receiving radio displays the caller’s ID on the screen (showing who is talking to them).

Could anyone please guide me on where to find this option in the software? Any detailed steps or advice would be greatly appreciated.

Thank you in advance for your support!

Best regards,
Marwan Nugdalla

The "Maintenance Mode Remote Device" usually occurs when you have a remote head configuration in which the brick has lost connection with the control head. This is usually due to the brick not having enough voltage to stay powered up. I would check to see how the brick is wired to the battery and make sure it is getting needed voltage.

The Radio ID (RID) display feature is found in CPS under Radio Ergonomics Configuration->Display->ID Display->PTT ID Display.
If you wish to have actual names assigned to the individual Radio IDs then you need to make a Call list under Call List Configuration where you would need to set up a UCL and individual call list then attach that call list to the personality or multiple personalities in which you wish to have the feature work.
The CPS Help files have a lot of great info on the above.

I have the same situation with a High-Powered XTL5000 radio. Based on the FL 1-90 error code and the recommended correction stated in the service manual, I ordered a couple parts to see if the radio will recover. I have one part on-hand and I am waiting on the other part. It should be here in a couple or three business days. I hope I can recover the radio back into a working order

Thank you so much for the detailed explanation! I really appreciate your insight on the "Maintenance Mode Remote Device" and error 09/10 issues. As you mentioned, we are using Motorola APX2500 radios, which are typically installed in vehicles as mobile radios. Based on the attached photo, the problem occurred when the vehicle's battery experienced issues. After the battery was replaced, the radio entered "Maintenance Mode."

When I tried to clone the radio from another working unit, I encountered no response. Additionally, attempts to read the radio from the CPS have been unsuccessful. I also want to add that I removed the radio from the vehicle and tested it in the workshop using a power supply, but I still wasn’t able to read or clone the radio.

Are you also getting the FL 1-90 error code?
no just Maintenance Mode Remote Device and error 09/10

If the radio brick doesn't respond to CPS and you don't hear the device connect/disconnect sound from your PC, it's dead and needs to go to the depot.
In my case, I hear the connection sound on the PC, but the CPS won't read or write. I was in the middle of writing a programming file and I lost power to the radio and controlhead. The affected controlhead works fine on another radio. The service manual said, turn the radio on/off, change ports, and replace the flex, I did all of that except replacing the Flex. I know the TIB isn't the problem because it will work on another radio so I have a Flex on order from Motorola. Unfortunately, I don't have another High Power Flex to swap around so it is on order to try and see if I can recover the radio.

Your radio is an XTL. Way different animal than an APX. The XTLs can be finicky. I'd try a recovery, you'll need a firmware refresh iButton and follow the procedure in CPS. Each time it will get a little further and further, this is ASSuming the radio is actually communicating with CPS.
Time to upgrade to an APX, XLTs are long in the tooth and not really worth investing time or money into. 20+ year old radios at this point.

The APX improved on the firmware update procedure from the XTL series. On the APX it will not start the update unitl the computer has transferred the whole update and verified it.

The XTL does it in real time and any little failure, power blip etc causes a radio to brick.

I replaced the Flex and it didn't resolve the problem. I really didn't have much hope, but I had to try it, it was only $60 for the Flex. I don't have the means nor the firmware to take this matter further so, I guess I have a new wheel chalk.

I would love to upgrade to the APX series, but I have plenty of spare XTLs so, I just stick with the XTLs for now.

Hi Everyone,

When connecting the radios to the PC, we hear the connection being established, but we are unable to perform any actions using the CPS. Additionally, the radios are displaying "Maintenance Mode" and "Error 09/10."

Please note that the APX2500 radios we are using do not have a separate head.

Could you please advise on the recommended course of action to resolve the "Maintenance Mode" and "Error 09/10" issues? Your guidance would be greatly appreciated.

Thank you in advance for your assistance.

In my case, there is good news. My radio was resurrected from the dead and is among the living now.

Apparently, when the power to the radio was interrupted, the codeplug got pissed off when the final checksum was not received and so when I restored the power, the codeplug decided to revert back to the beginning of its XTL life. That was why I was getting the maintenence mode remote device notification and the fatal error code FL 1/90.

What I understand, originally the XTL series mobiles were designed/introduced with the W series controlheads and was trying to look for the W series controlhead data, which is different than the O series controlhead data.

So, all you have to do is changeout the TIB for a W series controlhead and cable, fire up the radio, change the controlhead setting to the O series, power down the radio, change back to the O series TIB and cable and controlhead, and reload your O series codeplug file.

Try looking up the error code in the service manual and see what are the recommended steps to resolve that error

None of the XTL troubleshooting guides apply to an APX. APX radios are way better at handling firmware payloads. XTLS are ancient and not what the O/P has. So, getting back to the O/Ps APX, if the device is detected in Windows, what specifically shows up when connected? Look at your device manager and report back findings. It really sounds like the radio is bricked if it won't read/write in CPS and will most likely require a depot trip.

Yep. 99% chance it will be a Depot trip if an APX is showing the "09/10" error.
I have never been able to recover an APX after having that error and we deal with the APX line daily.
