Battery management:
The G933 Artemis Spectrum wireless headset is powered by a battery in the right ear cup. If you are not using the G933 Artemis Spectrum wireless headset, connect it via the USB port on the underside of the device to charge it. When completely discharged, the battery needs about 3.5 hours to reach a full charge from a standard USB output. For the best experience, connect the device and wait for a full charge before first use.

Logitech gaming software:

The headset's home screen in the Logitech gaming software has a battery level indicator. When running on battery, it will show the charge level.

Critical battery warning.

The Artemis Spectrum G933 gaming headset will play a tone when the charge is low. The headset's lighting will also be dimmed at a low charge level. At a critical charge level the device will play a sound and the lighting will turn off. Use the USB cable to connect the headset immediately if you hear these sounds, to ensure uninterrupted listening or gaming.

Idle sleep mode:
The G933 Artemis Spectrum will enter sleep mode to save battery power when it receives no audio signal within 5 minutes. In idle sleep mode the device's lighting will turn off and it will disconnect from the wireless USB adapter. To wake the headset from sleep mode, press any button on the device. The device will continue to draw battery power at a reduced rate in idle sleep mode. If you plan to leave the headset idle for an extended period, turn the headset off and connect it via USB to charge.
