Question: How to change the dock adapter? Can someone tell me how to remove the dock adapter without scratching or chipping the case? It looks like you have to pry it out but there must be a better way.Thanks
Document: We were looking for an attractive portable device with a decent quality speaker system. We tried this item and it's competition the Logitech Pure-Fi Anywhere 2. The Altec Lansing looks attractive in our home and doesn't take up much space compared to the longer Logitech. We had both systems in the same room and had others give their opinion by playing the same music on each without their knowing which device we were using. They picked the Altac Lansing each time. We all agreed this performed better all the way around.
That way, I can just grab it off the dock without having to put the case back on.
The added features look great but we like the looks of this better. It would be nice to have a remote that includes more and a handle but it costs more. The shiny plastic does show finger prints but I try to handle it carefully to avoid that. The remote is small but works. Wish it came with a case like the Logitech. For the price range and our use this is the best!
There's no visible way to do it, and it would be very easy to break the unit if you pry too much. I had to call support again for that, and they admitted it was not only not obvious but also not documented in the manual. If you need to switch the adapter, don't fiddle with it too much- just call Altec and get walked through it.
Of course, if you want to carry it constantly with you, you need to carry the power adapter (no, it's not just a power cord) and you may need to carry a couple of cables. While carrying it, you will want to keep the power adapter separate from the unit, so as not to scrath the plastic. A travel case would certainly help... but then you'd be accessorizing your accessory (by the way, Bose sells a travel case for Bose's Soundock system).5.
Looks like I got a dud. It doesn't change my rating though, as quality control in their factory is obviously lacking.
I bought this after extensive research and specifically wanting a portable item that I could take to the beach but also had a built in radio. Its nice neat slimline size is also an added bonus. I must admit, the sound quality is much better than I expected; my husband bought some surround speakers to go with his TV and I think the sound quality is as good as them and they were way more money!! ($$$!)
We are not using any of the inserts supplied just place it on the slot without, no problem. You do have to watch as you insert it that it is over the prongs correctly. I have a plastic protective backing on my iPod and I do not have to remove it to get it to work. We like the fact that it also includes an FM radio as well. It's been great in the house, on our deck/patio and for travel.
This product was reviewed by a a prominent magazine who rated it above more expensive units, and I agree wholeheartedly. The sound is much better than you would expect from such a small and compact unit, and it looks great too. I bought a second unit for my office. it folds up for compact storage and transport. I can recommend this unit without reservation.
Before purchasing this product, I borrowed a friend's bose ipod speakers (Can't remember the model, but the popular ones). The sound was only slightly better than these (Definitely not worth the price difference). The features of this product (FM Radio, easier navigation without remote, etc.) definitely out way the slight difference in sound production. The only bad thing I can say about this product is it is marketed as portable, but they made it out of a very easy to scratch and print plastic.
Answer: The notch in the front of the door looks like it should be it, but that's just a recess for the latch that holds the door closed.  There should be a small slit/notch in the back of whatever adapter you put in (take a look at one of the other adapters to get the idea of where it is).  You can probably pry it with a dime, but you can also use a sharp knife in the slot and just pull straight up -- comes out with hardly any force.
