    Anybody know anything about these Siemens Gigaset 2400 series cordless
    phones? Like how to take them apart for starters? Also anybody knows
    what this fix is all about often listed on eBay?

    IMPORTANT! By far the most common problem with Siemens handsets is
    "choppy" or "stuttering" audio. You may have been told you caused
    this by dropping the handset and damaging the RF shielding. We
    believe this is not accurate. We have found this problem usually
    originates from a "manufacturing shortcut" which is responsible for
    a premature failure in the audio section.

    Anybody know what they are talking about? A cold solder joint perhaps?
    Also anybody looking for online user manuals for these, I found them at:

    Don't waste your time with these phones.. I had 3 of them. 2 Bases (2410
    and 2415), 3 handsets, and 2 additional charging blocks.. hadn't dropped
    any of them, and it got so bad (same problem you mentioned) within less than
    a year, that I pulled them all, and got myself 3 $10 Uniden 900Mhz phones
    from Costco and they are still going nicely. I had gotten the siemens
    ones, and placed one base near one end of the house, and the other base at
    the other end. All 3 handsets where set to be able to use both bases
    (whichever was closer/within range in case I was outside with them). they
    worked great for the first month, and then they slowly deteriorated, to the
    point I was down to one decent handset (and this is the unit that eventually
    had dropped a whole 3 ft, onto my carpetted floor, and the LCD was dead, but
    it was the only one with the audio not cutting out - go figure..).. Thought
    it was the batteries, wasn't. Thought it was the placement of the bases, no
    difference.. they were just junk.

    Only reason I bought them was that I used thier 1.9Ghz equivalent models in
    Germany during one of my business trips, and found it handy to have multiple
    bases, with multiple handsets, and they could each handoff to one another
    seemlessly. The theory on the NorthAmerican model reamained reality for
    only 1 month before they started dying... Regarding how to open them, I
    know I did open one handset, and do vaguely remember there being some clips
    on the sides, but it's been so long I can't be for sure...

    If you want a decent quality 2.4Ghz phone, get a panasonic. I love them,
    and they last forever. NOTE: Yes there are lemons with every manufacturer,
    so I'm sure many will have horror stories. But overall they are pretty
    good, and they are pretty solid phones. Yes, you get what you pay for...
    Don't get me wrong, I got lucky that my $10 Uniden sets are still working
    nicely, except they are starting to get to the point they need a new
    battery, but wondering if it isn'y cheaper just to get another at $10 from
    costco.. :) Battery alone would cost me the same price, if not more...

    Good Luck..

    Yes I have heard the horror stories about these phones. Many from
    the chopping sound problem and now only 2 from the display quit on
    them. Although I've also heard that the modified refurbished
    handhelds are really terrific. And they work for years and years.

    The repaired and modified ones can be had very inexpensively from a
    few sources. Although I would like a shot to repair them myself. The
    first thing is how to open them up. I haven't tried too hard yet.
    But without answers, I may have to bust one open just to figure out
    the right way to take them apart.

    Anyway I did find your story to be very interesting and noteworthy
    nonetheless. Many thanks!

  4. I have several of these phones and have one handset with the choppy
    audio. I opened one up (a bitch) and found a decouplig capacitor was
    eliminated from the battery connection. It could be a problem with
    battery impedence (missing cap) because the units are time division
    duplex and probably have a large current transient when the transmitter
    turns on and off. This is just a though, I could be wrong. If you figure
    out how to fix these inclusing how to reliably open the housing I would
    be interested in knowing.

    I have 2 Siemens 2430's. The phones will randomly start stuttering and
    breaking up. When it happens, it gets progressively worse until you
    have to just hang up. Doesn't matter where you are when it can be right beside the base unit.
    problem, and the fix people are making corrects this defect. I still
    have not managed to find out exactly what the fix is, however.

    If anyone knows what exactly needs to be done to the phone to solve the
    issue, please pass it along. Would love to sort this out without
    having to throw the thing away.
