“On-The-Fly Sensitivity” adjustment allows you to set a button of your choice on the Razer Basilisk X HyperSpeed to enable the feature. If a button has been assigned to “On-The-Fly Sensitivity,” pressing and holding the assigned button down while moving the scroll wheel up or down will produce a bar on the lower right-hand corner of your screen allowing you to adjust your sensitivity settings by steps of fifty (50) DPI.

We cannot say with certainty what type of dirt and debris may be on your product, or how certain cleaning products may react with it, but we have had good luck cleaning Razer products using commonly available monitor cleaning wipes. To clean the body of your Razer mouse, please take a monitor wipe and use gentle wiping motions. Do not scrub the surface of your Razer mouse.
