Impressive features

With Bluetooth technology you can use the SL400A to pair with a compatible headset to enjoy calls comfortably hands-free. It can also be used to update the address book (which has space for up to 500 contacts), import image files for Picture Caller ID and/or music files for a personalised ringtone. And even when you are not around to receive calls, the SL400A has you covered with an answering machine that can record up to 45 minutes of messages.

Performance you can rely on

    A cut above the rest...very good phones indeed

    These are without a doubt the best phones that we have ever had the pleasure of using. I was hesitant about shelling out so much for a pair of landline phones, but I replace my mobile gets replaced every year with no qualms and I expect these to last for many years to come. My wife fell in love with them as soon as we opened the box - the handsets have a nice weight to them and they feel very well-made not to mention look stylish with the quality metal finish.\nAudio on them is absolutely astoundingly clear, even on hands-free, which is a definite plus. The ringer could be louder, but this has just given me occasion to carry one about in my pocket with the vibrate on (the battery on it seems to last forever).\nBluetooth was extremely useful in helping me to update the address book. I haven\'t yet added photos to my contacts, though may decide to do so in future. At the moment, the analogue clock screensaver suits me fine.\nAll in all, we have been mightily impressed, and I would highly recommend to anyone looking for good quality cordless phones
