The best STREAM ever as a wireless keyboard.

The CHERRY STREAM KEYBOARD WIRELESS is the wireless version
of the familiar STREAM KEYBOARD. The 2.4 GHz wireless key­board has all the features that have made its wired counterpart
so popular. The new STREAM KEYBOARD WIRELESS is the perfect
choice for all those who have been waiting for the wireless ver­sion of the CHERRY classic.

The wireless keyboard is plain but elegant, and will appeal to a
wide range of tastes. The slim design also reflects current trends.
With the feet up or down, it is clear that the wireless keyboard is
extremely stable, rigid, and non-slip. This is ensured by the inte­grated metal plate, the two feet and the eight rubber pads on the
underside.

At the heart of every keyboard is the key technology. Like all
products in the STREAM family, the STREAM KEYBOARD WIRELESS
uses CHERRY’s own SX scissor technology. This ensures uniquely
comfortable, precise and quiet typing. All these attributes lay the
foundation for productive work and make the flat keyboard the
ideal companion in the office or at home.

The 2.4 GHz wireless connection is also reliable and uncompli­cated. The keyboard comes with a plug & play receiver to con­nected to the PC. Thanks to wireless technology with a range of
10 meters and AES-128 encryption, the desktop is no longer a tan­gle of cables but tidy space for you to work in comfort.

The computer keyboard has a full-size layout and a number pad,
which means it immediately feels familiar. There are also useful
status LEDs integrated in the CAPS LOCK, NUM and SCROLL LOCK
keys.

This feature is usually only found in higher price ranges. The red
status LED shows you at a glance whether the Caps Lock key is ac­tivated, for example. In addition, the LEDs flash when you need to
change batteries. However, with a battery life of up to 36 months,
this rarely happens.

In any work environment, users require certain functions particu­larly often. The CHERRY STREAM KEYBOARD has handy extra keys
for the most important functions. These include six keys for con­trolling your multimedia player. Three other keys for the browser,

e-mail and calculator can be easily accessed. The lock key is espe­cially invaluable in the office environment. The user can simply
press it to log out when leaving the workstation.

Additional flexibility is offered by the CHERRY KEYS software. It
can be downloaded free of charge from www.cherry.de. With just
a few clicks, you can configure the office keyboard any way you
want.

Environmental protection and sustainability are matters that
comprise many aspects. With the CHERRY STREAM KEYBOARD,
for example, we have managed to make the packaging completely
plastic-free. It has also been honored with the oldest of all envi­ronmental protection labels, the Blue Angel. In addition, the key-

board bears the GS “safety tested” seal. The only legally regulated

test mark in Europe certifies compliance with defined ergonomic
and safety standards. All these criteria provide guidance for sus­tainability when buying products, as well as for the health and
safety of your employees.

The STREAM KEYBOARD WIRELESS is the perfect wireless
standalone keyboard for frequent users with high demands.
Based on CHERRY SX scissor technology, the wireless keyboard is
quiet, durable and requires no maintenance. It is ideal for anyone
who appreciates the advantages of the STREAM KEYBOARD but
also wants the benefits of wireless transmission.
