Does Windows 7 have Bluetooth wireless connectivity?
In Microsoft Windows 7 and earlier, Bluetooth wireless adapter manufacturers developed their own unique drivers for connectivity. While the CORSAIR K63 Wireless Keyboard has been validated in Windows 7 with the included USB wireless receiver (2.4GHz wireless mode) and USB data / charging cable (wired mode), the variability in manufacturer Bluetooth wireless drivers may cause some users to experience Bluetooth connectivity issues.
CORSAIR recommends the following solutions to resolve Windows 7 Bluetooth wireless connectivity issues:
Upgrade to Windows 10 and use the built-in universal Microsoft Bluetooth wireless driver
Highly recommended as Microsoft has ended mainstream support for Windows 7
Try using one of the following Bluetooth 4.0 or higher USB adapters
At CORSAIR we wanted to deliver the amazing capabilities of our wired keyboards while offering excellent wireless battery life, but understand that some customers may want maximum backlighting regardless of power consumption. The 100% LED brightness setting can be enabled via CUE, but will noticeably reduce battery life.
Does CUE work over a Bluetooth connection?
CUE support is only available via 2.4GHz wireless and USB wired modes.
Why is a USB 3.0 or USB 3.1 (Type-A) port a minimum system requirement?
To ensure that the K63 Wireless Keyboard charges as quickly as possible it requires more power than a USB 2.0 port can provide.
Why does the LED backlighting automatically turn off?
The keyboard backlighting will turn off after 15 minutes to save power when idle, but will return upon key press. This feature can be adjusted or disabled via CUE.
Backlighting will also turn off when the battery is critical and will be automatically restored after charging.
How do I extend my battery life?
CORSAIR recommends using the low (33%) brightness setting to achieve the best combination of vibrant illumination and long battery life (up to 25 hours). Turning backlighting off will greatly extend battery life up to 75 hours.
How do I factory reset my keyboard?
To reset the keyboard to factory settings, hold the ESC key while turning the keyboard on, then release the ESC key after two seconds. The keyboard will then power on normally.
