Vuzix Wrap 920 VR Bundle - Manual (Page 30)

Four bars indicate a fully charged battery. When the remaining battery level drops to
approximately 10% the indicator will display only a single bar and a low battery
indicator will be displayed regardless of the OSD display status.
Note: Some batteries, such as rechargeable units, may not display four bars even when fully
charged.
Audio Level & Controls
Your Wrap video eyewear is equipped with removable noise isolating earphones and
three sizes of noise isolator inserts.
Medium sized noise isolators are pre-installed on the earphones but these can be
slipped off and replaced with larger or smaller isolators for the best possible fit.
Wrap earphone volume adjustment is made using the Adjustment Buttons on the
Control Box when the OSD is not displayed.
Tip: If you are using an alternate speaker system, you must use the volume controls
provided with that audio system.
PC Audio
When you connect your Wrap eyewear to a Windows based computer, the operating
system automatically reconfigures your system to use the Wrap earphones. If you
wish to play audio through an alternate sound system, use the Windows Sound and
Audio Devices Control Panel to enable the preferred audio system.
