XE500 RSM channel knob inconsistent

[human8472]

I am posting this just in case someone else has run into the same issue. I think my XE500 RSM is defective because when I change channels using the channel know on the XE500 it doesn't always switch to the proper channel. The channel selector knob on my APX6000 works perfectly every time, but when I use the channel selector knob on my XE500 RSM it will sometimes work and other times it won't. It typically switches channels on position 1 and 2 properly as it should, but when I move it to position three it sometimes changes to the channel but most times it does change the channel. Sometimes it will change the channel and then a few seconds later switch to the previous channel without me doing anything.

Like I said, I think my XE500 needs to replaced or repaired but I just wanted to check in case this is a known issue others have run into.

Just curious, what firmware version is your 6000 on?

 

[human8472]

v25 I believe

I sent the XE500 back to the seller and they offered to replace it. However, when I get the new RSM it does the exact same thing. When I turn to the 3rd channel position using the channel knob on the XE500 the channel does not switch. However, using the channel knob on the APX6000 itself works no problem.

Or maybe they sent the exact same mic back to you...

I was wondering the very same thing. Seems like a rather big coincidence that it fails on the exact same channels as previous.

That's a loose channel knob with a broken piece inside. It probably the most common failure point on the APX radios and RSM. Can you PM me the serial number. I can check if it's still under warranty. You'd just have to find a proper Motorola dealer near you to get it fixed.

Thanks a bunch! I will post that serial number as soon as I get off shift. I did purchase it on eBay so I have no hopes for it being under warranty, however, is it something a Motorola repair shop can fix?

Yes, a shop can take care of sending it Motorola and have depot fix it. They may fix it in house if they have a good bench tech though.

So looking at the sticker on the RSM this is what I see
