following conditions:
• Receiver audio set to EQ = OFF, V LIMIT = OFF
• Audio output at bodypack: Pink noise at 100 dB SPL in ear with SE112
earphones (impedence at 20 Ω)
Power-save mode: When there are no earphones plugged in for 5 minutes,
the receiver enters power-save mode to preserve battery life. The LED slowly
fades on/off in this mode and continues to display the color that represents
the remaining battery life.
