Audio breakup

Hv latest firmware 6600M and PGXL. On last install, 2 issues started: a) audio intermittently breaks up, b) interlock warning sometimes appears on radio. Ideas?

    Hi Rich,

    Specifically which versions of radio and amp firmware. I’ve seen where a person has multiple versions of radio software on their desktop (shortcuts) and inadvertently click the wrong version and downgrade by mistake.

    For reference, please post exact versions.

  • Using all the latest Firmware. However, your question has me thinking. I could not strictly follow the sequence to update because at one point you are to hold down the off/on button. I am still far away from the radio, using a Maestro. Not sure if holding down its button would have done the same. Don't think so. However, all firmware seemed to register OK.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
