Hi

Anyone know if the above UHF radio can be factory reset or if all user config can be cleared?

Have a situation where the squelch always appears to be open as if signal is received but don't hear anything.

Control of the squelch by button and screen indicators appears ok 

Transmits ok.    

Have a second unit which is ok and have compared configs on both units which are the same.


TIA for any help.

Cheers

I assume you've tried taking the battery out? Tried swapping the battery packs between the good one/bad one?

I have the same problem with the same model. Out of 4 units that I have, one is doing exactly the same as you described. 

Have done everything, settings,battery swap, with no luck.

Yep. Taken the battery out. Tried swapping batteries.
Tried leaving the battery out for a long time.
Tried pressing various keys and combo of keys during power up.

Haven't taken the back off yet. Bit reluctant to go that far.

Don't know the full history and how much punishment the units might have received.
The cases don't look too bad. The units are about 3 or 4 years old.

Might be time my rellies bought some new ones !!!

Cheers

Did not get anywhere.
Can't remember the full symptoms now.
As I recall there was a faint zzzzzzzz-ing in the speaker on receive.
No sign of any receiver getting through.
I summised that with the low cost of these units the the whole thing is probably one IC anyway and perhaps not repairable. (This may pull in some more knowledge from someone!!)
I did not pull the unit apart and decided my rellies should perhaps buy a new pair.
Seems from the comments that the failure is not uncommon.
 
Cheers

I dont think Im quite understanding what you're saying.

So the RX light is on? or there is noise coming from the speaker?

If the RX light is on, but you aren't hearing anything, you may want to check your CTCSS/DCS settings (you probably already have, but it cant hurt to check again!)


Generally there is a sequence between turning the radio on and holding down a button.
you could try a number of tests on your radio.


For example, with my old UH-040,42,44's, you held down the scan and DUP buttons while turning the radio on, it reset all the settings (including CTCSS, Priority Scan, normal scan, as well as everything else).


Hopefully thats on some help.

As it was quite a while ago. I don't remember all the details.
I did configure all the settings in the bad unit the same as the good unit.
That did not help.
Not sure what the state of the Rx LED was.
I am sure the faint zzzz-ing was from the speaker all the time.
I did try pressing a lot of button combinations at power up to reset the unit, but can't be certain if I tried the particular sequence you suggested.
It will be interesting if some other reader tries your reset sequence.
I don't have the units with me... they are a few hundred km from here.
I did try and work through a logical set of tests....
Thanks.
Cheers.
