CHERRY Stream SX (JK-8550EU-2)

CHERRY STREAM

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 key-

board 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 ver-

sion of the CHERRY classic.

The heart: CHERRY SX scissor technology

 The STREAM family is known for its good typing feel, but what exactly constitutes a good typing feel? We think that precise movement of the scissor mechanism and a defined pressure point are essential. Furthermore, the quality must remain the same over a very long time. Also, the noise level whilst typing must not be disturbing, particularly when several workstations are located in one office as a quiet working environment can increase productivity. It’s a good thing, then, that this wireless keyboard from CHERRY is equipped with whisper-quiet keys.

 

       

Familiar handling – making searching a thing of the past

The wireless keyboard with 2.4 GHz wireless technology and AES-128 encryption makes tedious key searching a thing of the past. It has a full-size layout and a number pad, which makes operation immediately familiar. Stauts LEDs for CAPS LOCK, NUM and SCROLL LOCK are helpful as they are integrated directly into the key, showing which status LED is activated at a glance. This feature is more commonly found on products at higher price points. A pending battery change is also clearly indicated in good time by the LEDs flashing. However, the long battery life of 36 months ensures that this is a rare occurrence.
