Test or replace the headphone batteries before performing the circuit/system verification.

  1. Turn ON the wireless headphones. Verify the power indicator lamp on the wireless headphone illuminates.
    • If the power indicator lamp does not illuminate, replace the wireless headphones.
  2. With the Radio ON, RSA ON, and DVD playing, verify all of the headphones are working properly.
    • If all of the headphones are inoperative, or the sound is distorted, refer to Circuit/System Testing.
