    Well ... It took more than two months for my replacement battery to wend its weary way from China but I fitted it yesterday (the old one felt like an infected paper bag) and (as far as I can tell) everything is now OK and my display looks normal.

    Not a five minute job dismantling the Maestro and then the tablet itself but much more cost effective than sending the box in for repair!

    Thanks to all who responded and offered advice.  What I was unable to find (probably my lack of search skills) was a procedure to dismantle the Maestro.  Anyine know of one?

    Supplementary question ... What is FlexRadio's recommendation about the Maestro and power?  I had been leaving mine connected to the mains power supply 24/7 because it sits on my operating desk and doesn't go anywhere.  

    I have disconnected the internal battery but should I pull the power plug out of the back between operating sessions?

    Recommendations please.

    it is not recommended to leave the power on permanently the tablet inside it is always in charge which overcharges the battery and makes it swell.

    Thanks Jean. A sticky label to remind me to pull the cable is in order I think. Does this also apply to the Mk2 Maestro?

    Connect the Maestro  to your station power supply at 13.9v. When you use the radio the Maestro charges. Ideally recharge it for a few hours a month if you don't use it (especially version A)

    For the Maestro "A" (power button on the top), you should connect it to a 13.8 VDC power source once every 4-6 weeks for about 24 hours.  This is not needed for the MAestro "B" (power button on the side).

    For Maestro "B" can we leave the 13.8 VDC connected 24/7 or is the a problem?

    In general, the answer is yes, it is OK.

    We evaluate a lot of new emerging technologies for future products, so it may be possible.

    Decided to change my Maestro tonight after having the screen spots above for about 4 years.

    A new battery is ~4mm thick, my battery was swollen to ~18mm

    I have the version A, the first delivered in Canada. I have had it connected 24/7 to power and use it roughly 8 to 9 hours daily. Knock on wood no issues. Perhaps I'd better open it up to look for any signs of the battery on the tablet swelling.

    I have two "A" models I have left on 24/7 for the last year. Neither has experienced the swelling issue. However, I am now pulling the power when not in use with a note to do a 7 day charge every month.
