The Remote Control Is Not Responding?

Possible Causes:
- The batteries are low or depleted.
- The remote is not pointed at the main speaker's infrared receiver.
- The remote is too far away or positioned at an unsuitable angle.

Solutions:
1. Replace the batteries with two new AAA batteries.
2. Point the remote directly at the front panel of the main speaker. The specified operating range is over 10 m, with an infrared reception angle of ±45°.
3. Move closer to the speaker and try again to rule out distance-related issues.
