The CHERRY GENTIX DESKTOP is a combination of a wireless keyboard and mouse for operating PCs and laptops. For information on other products, downloads and much more, visit us at www.cherry.de

for your saftey

Danger of explosions due to wrong or incorrectly inserted batteries
Only use batteries of the type named in the 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.
Take several short breaks, with stretching exercises if necessary.
Change your posture often. 2 Connecting devices to the PC/laptop
Slide the battery cover of the mouse backwards and remove the red receiver.
Connect the receiver to a USB 2.0 port on your PC/ laptop if possible (this usually has a white or black guide).
Insert batteries into the keyboard and mouse.
Set the switch on the bottom of the keyboard and mouse to “I”.
If the wireless connection is successful, the keyboard’s scroll key and the mouse wheel will flash for about 10 seconds.
Storing the receiver in the mouse
The receiver is so small that it can stay in the USB socket of a laptop while being transported. To protect against dirt and loss, remove the receiver and place it in the battery compartment of the mouse.
Setting the DPI rate of the mouse
The speed of the mouse pointer increases with the level of the DPI rate.
To change the DPI rate, press the DPI button on the top of the mouse.
The LED flashes according to the setting:
1x = 1000 dpi, 2x = 2000 dpi
The setting is saved in the mouse and is retained even when the mouse is switched off.

5 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.

6 Battery status
When the voltage of the batteries of the keyboard or mouse decreases, the LED of the scroll button or the LED in the mouse wheel flashes, depending on the device. If you are working with one of the devices or wake it up from standby, its LED flashes 10 times, then the signal stops.
• Replace the batteries as soon as possible.

7 Switching the devices on and off

When not in use, the devices switch to sleep mode, which requires much less power. They switch on again automatically as soon as you press a button. Because they still consume some power in energysaving mode, you should switch them off manually for extended periods of non-use or for transporting.

Slide the switch on the back of the keyboard or the bottom of the mouse to the appropriate position: Off = 0, on = I

Cleaning the devices

Switch the devices off.
- NOTE! Aggressive cleaning agents and liquids can damage the devices
- Do not use solvents such as benzene, alcohol, scouring agents or abrasive scourers for cleaning the devices.
- Prevent liquid from getting inside the devices.
- Do not remove the key caps of the keyboard.
Clean the devices with a slightly damp cloth and some mild detergent (such as washing-up liquid).
Dry the devices with a soft, lint-free clot

If the devices do not work

Switch the devices off and on again.
Check whether the batteries are inserted correctly and have sufficient voltage.
Connect the receiver to a USB 2.0 port on your PC/laptop (this usually has a white or black guide). Malfunctions occasionally occur on USB 3.0 ports (blue guide).
Connect the receiver to another USB 2.0 port on the PC/laptop.
Reduce the distance between the receiver and the devices by connecting the receiver to a USB port that is close to the devices.
Use a USB extension cable to place the receiver as close to the devices as possible.
Make a new connection between the keyboard and the receiver:
- Disconnect the receiver from the USB port and plug it in again.
- Within 10 seconds, hold the keyboard as near to the receiver as possible, then press the “Esc” and then the “Q” key. If the LED in the scroll button flashes for about 10 seconds, the connection is established.
Make a new connection between the mouse and the receiver:
- Disconnect the receiver from the USB port and plug it in again.
- Within 10 seconds, hold the mouse as near to the receiver as possible then press the mouse wheel and the right mouse button at the same time. If the LED in the mouse wheel flashes for about 10 seconds, the connection has been established.
