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.
Note: Battery life using Energizer brand AA Alkaline batteries and the following conditions:
Receiver audio set to V LIMIT = 0dB
Transmitter audio INPUT set to Line+4 dBu and Level set to −9 dB
Audio input to the transmitter: pink noise at +8.7 dBV
Audio output at receiver: 115 dB SPL in ear with SE425 earphones (impedance at 22 Ώ) set at volume level 4.
Note: Using lower-impedance earphones or ones with different sensitivity, different battery types, and higher gain settings in the PSM system may cause the
receiver battery life to be different than specified.
