Panasonic KX-TG8421

The Panasonic KX-TG8421 makes her a lot visually. Even some luxury sprayed the frame in metal optics to the handset, the base is living room compatible. Ergonomics is also true: the handset is tired of in the hand and pleasant to the ear.

The buttons also deserve praise: the individual buttons are large and brightly lit. At best the joystick, which has something much play in all directions gives rise to the criticism, also the soft keys below the display might stand out a little further out of the housing.

Praise is there again for the representation on the display: the when dialing the digits in the XL mode displays, what should it not only see weak contemporaries. In the phone book, a magnification function for font and numbers available is on top at the push of the right soft key. Also practical: About the function “Increase”, you can activate an additional language optimizer.

Ease of use

The menu is well managed: shows the dial-up points with icons on the first level, is controlled by the whole of the joystick and soft keys. Very laudable: Also a night mode is the call tone settings. Here, you can set the device in a certain period of time is not ringing. Unfortunately, this setting applies only to the handset, the base ring must be manually disabled.

There is praise for the very loud on request ringtones, criticism for the fact that you the ringtone does not with push of a button and can switch off. Although the device allows hands-free chatting thanks to hands-free or with an optional wired headset, looking for a baby monitor function but also in vain as a display at the base, which shares with the number of messages on the otherwise great machine.

Also on board: Radiation reducer eco fashion, unfortunately only in its original version, which only shuts down the power of the base if the handset to charge inside the shell. one, by the way, not a book may more than one handset in this mode.

The best is the enemy of the good

At least, the Japanese of the new product range have bought now switching power supplies that press the power consumption during typical daily operations on 1.4 Watts. Less great is the fact that the k-x TG8421 does not encrypt the calls between the base and handset delivers – the devices should dominate at least that delivered starting in the autumn.

Points could get Panasonic at the endurance and sound measurements: the handset must be relatively rare to load, even when the sound measurements the Panasonic did a good job. ERGO: The fully-eco-mode and the missing encryption the Panasonic moves technically on top level.
