Important Usage Information
w Battery:
1. We recommend using alkaline batteries for a longer battery life.
2. Always change batteries when battery low alarm appears, otherwise the mouse or keyboard will shut down once the battery
voltage is too low.
3. Don't mix different types of batteries or new and old batteries together. Always replace old batteries with new and same type
batteries.
4. Remove batteries after long periods of non-use. Battery leakage or corrosion may damage the device quality and cause
danger.
w Mouse usage:
1. This optical mouse senses light to detect mouse’s movement; therefore, it cannot work on a glass, translucent, reflective, or
dark color surface.
2. The mouse can work only on a clean, flat, non-slippery, opaque, and light color surface in order to ensure smooth and
accurate cursor action.

1. Mouse battery low alarm:
- When the mouse battery is low, the RED LED indicator under mouse scroll wheel will blink when the mouse is moved.
