answering machine, MyFRITZ!, Smart Home, FRITZ!Fon and NAS create new possibilities
and really step up convenience.

Would you like to update your FRITZ!Box with the new functions?
All you need to do is use the update wizard to search for the new version of FRITZ!OS.
Once the update is available, you’re only two clicks away from conveniently bringing
your FRITZ!Box up to date. This means FRITZ!OS 5.51 has over 100 new functions and
improvements for your FRITZ!Box, all of them completely free of charge.

The versatile answering machine now has its very own menu item in the FRITZ!Box user
interface. Messages can now be played on the start page itself and the new timer makes
everything that much more convenient: all you need to do is define the times when the
answering machine is to be active.

Leave yourself and others a voice message using the memo function – it really couldn’t
be more simple! You can also forward your new messages and memos via e-mail so that you
can listen to them on your smartphone or tablet, for example.

MyFRITZ! now available as an app – and needing just one password
With MyFRITZ!App, you can now keep an eye on your home network on the go.
This means you can conveniently access your calls, voice messages and your Smart Home devices.

The popular, free-of-charge MyFRITZ! service – the cloud you can trust – is now even more
convenient and easy to use, and just as secure as ever: with the new FRITZ!OS 5.51, all
you need to access the services MyFRITZ! and when on the go is to register once
– meaning you can connect to your home FRITZ!Box in record time from your smartphone or
office computer

FRITZ!OS – fit for Smart Home
FRITZ!OS 5.51 enhances the plethora of possibilities available on your FRITZ!Box by taking
it into the new Smart Home area. Together with the upcoming intelligent socket FRITZ!DECT 200,
you can conveniently operate your electrical devices – whether you’re using a PC, tablet or
your FRITZ!Fon. Smartphones can also be used in conjunction with the MyFRITZ!App
(Android and soon for iOS) for ease of operation.

Intelligent switching programs will make life with the FRITZ! Smart Home even more pleasant
– and with functions such as random switching, even more secure. So you’ll be able to leave
it up to FRITZ!DECT 200 to manage the sunrise/sunset function – or use your Google Calendar
for the switching commands. FRITZ!DECT 200 will also measure the energy consumption and
related costs of networked devices, even over longer periods and, on request, send you
this information via e-mail.

New features for a true star: the FRITZ!Fon
FRITZ!Fon now features a favorites list that makes it considerably easier to access your
favorite functions. This is also where you’ll find the new media player, Smart Home and your
web radio. A further new feature of the FRITZ!Fon MT-F is the start screen, which instantly
provides you with an overview of the key events, such as incoming calls, e-mails, and voice
messages. And with the new search function, you’ll find the contact you’re looking for in the
telephone book more quickly – by their first or last name.

Your FRITZ!Fon can also be used in conjunction with the FRITZ!DECT 200 as a remote control
to manage all devices connected via the intelligent socket. So you can conveniently switch
your Smart Home devices on and off, and monitor power consumption.

Multimedia and music, whenever and wherever
FRITZ!OS 5.51 brings a media player to the FRITZ!Fon cordless telephone for the first time.
The player will conveniently play the music saved on your FRITZ!Box and/or other media servers.
With FRITZ!Fon, you can also define which songs are played on other UPnP-enabled devices, for
instance on the FRITZ!WLAN Repeater N/G or speakers with wireless capability.

Alternatively, you can deploy your Android smartphone, or FRITZ!App Media, as a convenient
way of managing your media library.
