XPR6550 Audio issue

I just received a new VHF XPR6550.
Model# H55JDH9LA1AN
Firmware Version: R01.06.00
Codeplug Version: 06.00.09

Problem, When receiving tones, the radio cuts out or the tones are distorted, but the voice dispatch comes over clear. Is there a setting that detects the tones and tries to mute them?

Any help would be great.

Thanks, Chris

Look in to upgrading your firmware... They are at least up to R01.06.10 (as of a couple of months ago - I don't know what is current) so I'm sure there have been some fixes since.

Digital radios in general are famous for their poor ability to reproduce audio tones. There is another thread active on this subject regarding TRBO radios that says, I believe, that Motorola is working on a fix, or at least an improvement, for this problem.

What type of tones are you trying to send?

If it DTMF, the new firmware version 1.7 allows for DTMF regeneration on digital.

Is the unit decoding the tones correctly?
