Battery replacement on Yamaha FS1R

Yesterday my FS1R came up with a “Battery Low!” warning after I had already done the replacement on my M1R and TX802 one year ago. Fortunately again, the CR2032 button cell sits in a holder. Note the Sanyo LC78834 DACs.

    Thanks for this! My FS1R battery just went out tonight! Wish I would’ve read the part about losing the memory once it was turned off though!

    This is a very useful guide! Note the unit must be opened at the bottom.

    Wow, mine just went out, wonder what determines life, I have gear from the 1980s that still have original battery…

    THANK YOU! It worked!
    I would never have done it on my own without your blog.

    1) Open the unit by unscrewing the bottom and 3 additional screws from the front panel bottom.
    2) remove the battery by gently sliding it back in the holder and then lifting at an angle.
