Cable needed: Any generic 3.5mm audio cable.
- First remove the nosepiece by gently pushing it downward off of the optical unit. With your fingernail or edge of your finger, gently push in the lenses until they click into the optical unit.
- Attach the provided magnetic lens cover to the inside of the headband covering the lenses, extend the headband to accommodate your head and slip the device on your head with the headband facing upward.
- Plug your audio cable into the recessed 3.5mm audio input and make sure the power is OFF. Plug the other end of the audio jack into your music playback device and adjust volume on that device.
NOTE: The recessed audio input is designed for use with audio cables having a slim, cylindrical housing; Use of cables with other housings may prevent the jack from being fully inserted into the receptacle.
When using as a set of audio-only headphones, the volume buttons on the ear cans do not work.
In audio-only headphone mode, the power is off so volume must be controlled from the playback device or with an optional audio cable with in-line volume controls.
