  1. 1) Model: Fender Chroma Polaris


    2) Mattery Type: Akaline D-cells (2)


    To replace: First, UNPLUG THE UNIT because the main power runs directly near the batteries. Unscrew the two large silver screws on the bottom, one on each end, they hold the top panel down. Be aware that the screws are captured and will not come out. When they disengage from the top, the top will be free to hinge open from the back, so be careful not to let it flop open if you have it upside down. The batteries will be immediately apparent. If you are reasonably swift in your replacement (within several seconds, I imagine), your programs ought to remain intact during the exchange. To be on the safe side you should make a backup of your data, just in case.

  2. 1) Model of Synth: Korg EX-800


    2) Battery Type: CR2032


    Another leggy battery. It's located on the main board at the bottom of the case, situated rather tightly between two chips. The original battery had an odd leg geometry and was surface mounted; The leg pins did not feed through the board. Replacing it requires taking a leggy CR2032 and bending the ends of the legs slightly so they can be soldered to the largish pads on the board. Due to the close proximity of the battery to the pins of nearby chips, you might consider placing an insulator between the battery and the chips. I used a short length of shrinkwrap tubing and stuffed the battery into it with the legs poking out the ends.

  3. IMHO, part of the joy of real piano ownership is the twice-annual visit from the tech. He takes real good care of it, well worth the money.


    Once tuned, even the best pianos start to go out of tune; Just how badly/quickly depends on not jsut the piano, but how it's been tuned in the past, how frequently it's retuned, and environmental conditions. Swings in temperature and humidity will make matters worse.


    I find that on my own piano, which I keep in a house that's generally stable temperature and humidity wise, still goes noticibly out of tune after a couple of months, and by the time the tech is on it again, it REALLY needs it. But then, I'm picky. :) Also, it seems that it's going longer now before it gets bad. It's still a young piano.
