Razer DEATHADDER ESSENTIAL Master Manual page 24

If you should experience any physical discomfort while using your mouse, such as pain, numbness, or
tingling in your hands, wrists, elbows, shoulders, neck or back, please consult a qualified medical
doctor immediately.
MAINTENANCE AND USE
The Razer DeathAdder Essential requires minimum maintenance to keep it in optimum condition.
Once a month we recommend you unplug the device from the computer and clean it using a soft
cloth or cotton swab to prevent dirt buildup. Do not use soap or harsh cleaning agents.
To get the ultimate experience in movement and control, we highly recommend a premium mouse
mat from Razer. Some surfaces will cause undue wear on the feet requiring constant care and
eventual replacement.
Do note that the sensor of the Razer DeathAdder Essential is 'tuned' or optimized especially for the
Razer mouse mats. This means that the sensor has been tested extensively to confirm that the Razer
DeathAdder Essential reads and tracks best on Razer mouse mats.
