For your safety

Risk of choking from swallowing small parts

• Keep the device out of the reach of children under 3 years.

Danger of explosions due to wrong or incorrectly inserted batteries

• Use only nickel-metal hydride rechargeable batteries (see "Technical data").
• Insert the batteries in accordance with the markings (+/-) in the battery compartment.

RSI stands for "Repetitive Strain Injury".

RSI arises due to small movements continuously repeated over a long period of time.

• Set up your workspace ergonomically.
• Position the keyboard and mouse in such a manner that your upper arms and wrists are outstretched and to the sides of your body.
• Take several short breaks, with stretching exercises if necessary.
• Change your posture often.

Avoiding damage

Damage to the batteries or device

• Only charge the batteries in the device. Do not use an external charger.

Connecting the receiver to the PC/ laptop

1. Connect the receiver to a USB 2.0 port on your PC/ laptop if possible (this usually has a white or black guide).
2. Slide the switch on the back of the keyboard and the bottom of the mouse to "ON".

Set the sensitivity of the mouse (DPI rate)

You can change the resolution of the mouse sensor between 1000 and 2000 dpi for precise work. The speed of the mouse pointer increases with the level of the DPI rate.

• Press the left and right mouse button at the same time and turn the scroll wheel.
  Scroll down = 1000 dpi, scroll up = 2000 dpi

Charging the batteries

Charge the batteries of the respective device when the battery status LED flashes red. Charging the batteries in good time prolongs their service life.

• Connect the charging cable to the socket on the device and a USB port or USB network adapter.

Your power source (PC/laptop) must be switched on.

You can continue to work while it is charging. The LED lights up red.

When the battery status LED goes out then the device batteries are fully charged. The charging circuit prevents overcharging.

Surface under the mouse

The mouse is most effective on a light-colored, textured surface, which saves energy and ensures optimal motion detection.

A reflective surface is not suitable for using the mouse on.

Configure devices individually

With the CHERRY KEYS software you can freely assign the mouse buttons and many keys on the keyboard. This allows you to access apps, files, individual text modules or macros at the touch of a button.

You can obtain CHERRY KEYS as a free download at www.cherry.de.
