Battery life was measured using Energizer™ alkaline batteries, under the
following conditions:
• Transmitter sensitivity: Line (+4dBu)
• Audio output from receiver: 100 dB through Shure SE112 earphones
Power-save mode: When there are no earphones plugged in, the receiv-
er 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.
