Warranty Information
Warranty information not explicitly stated as a period, but refers to general household purposes.
Basic Operation:
- Normal Use: Set the power switch to OFF. Music can be heard in 2-channel stereo, but noise-canceling and SRS surround effects are disabled.
- Noise Canceller: Set the power switch to ON1. The green indicator lights up, and ambient noise is reduced in 2-channel stereo playback.
- Noise Canceller + SRS Surround: Set the power switch to ON2. The green indicator lights up, and both noise-canceling and SRS surround functions are active for a more realistic, three-dimensional sound experience.
- Using the Headphones: Attach the connection cord to the headphones and your music device. Adjust the headband length and place the earcups over your ears. Use the volume dial to adjust sound.
Storage: Reverse the ear pads, fold the headband, and align with the ear pads.
