logitech G903 Lightspeed Wireless Gaming Mouse User Guide

What’s in the Box

SETUP INSTRUCTIONS

1. Remove the protective film on the bottom side of the mouse before use. This film is designed to protect the sensor from dust during transport, and your mouse may not function unless this is removed.
   
2. A wireless receiver, USB adapter, and optional 10g weight can be found in the accessory box. Plug one end of the cable into your PC, and the other end into the USB adapter and receiver.
   The receiver can also be used plugged directly into your PC.
   However, using the cable and adapter when in wireless mode is recommended and allows for better connectivity and easy access to the cable for recharging.
   
3. Turn mouse on via the switch on the bottom of the mouse.
   
4. To charge, disconnect the cable from the adapter and plug into the front of the mouse. Your mouse will operate in data‑over-cable mode whenever it is plugged in directly to a PC. Full charge from empty requires approximately two hours plugged in to a PC USB port.
   

Tips: 

• Keep the mouse and receiver 2 m+ away from wireless routers or other 2.4GHz wireless devices to minimize environmental noise.
• G903 has a wireless range of up to 10 meters. To ensure optimal performance in noisy wireless environments, and to keep the charging cable easily accessible, it is recommended to keep the receiver within 20 cm of the mouse.

• Charge level can be checked when the mouse is powered on or using Logitech Gaming Software to assign a button to check charge level.
• Charge level is displayed for seven seconds at mouse power‑on using the color and number of bars illuminated on the DPI indicator:
  • 3 green bars = 50–100%
  • 2 orange bars = 30–50%
  • 1 red bar = 15–30%
  • 1 flashing red bar = <15%
    Tip: You can program a button to show charge level using LGS.
• The left DPI LED will flash red when battery is at 15% or less.
  When this happens, plug in your mouse to charge.
• Charge level, power draw, and estimated remaining battery life can be checked in Logitech Gaming Software

Battery life and capacity may vary with age and use. Rechargeable batteries have a limited number of charge cycles.
