IR Keyboard Desktop
Separating the keyboard from the power supply enables a symptom-free usage of the
computer. Thereby the computer and screen should be held as radiation free as
possible and a remaining radiation should be avoided with great distance. Moreover,
aids like shielded cables and radiation-free peripheral devices may need to be installed
The 86-keys keyboard can take on all functions of a standard 104-keys keyboard. The
19.05 mm spaced keys are also comfortable for big hands and have a perfect tactile
feedback. Additionally there's a special dirt-repellent Trackball with high resolution.
The infrared transmission provides a range of 5 meter with a receiving angle of ±30°.
The keyboard is running independent from the power supply with 2 pcs. AA batteries.
For daily use it is recommended to use rechargeable NI-MH batteries.
The IR-Keyboard is the best solution to avoid a low-frequency field which eventually
can harm the user. Furthermore the keyboard is ergonomically designed, has a long
battery-operating period and is very robust.
The verification in the lab still needs to be done. The following values are just provi-
sional target figures.
