Battery Life

Note: Battery life using Energizer brand AA Alkaline batteries and the following conditions:

• Receiver audio set to HIBOOST = OFF and V LIMIT = OFF

• 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(impedence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.

Pink noise is a signal with a frequency spectrum such that the power spectral density is inversely proportional to the frequency. In pink noise, each octave

carries an equal amount of noise power.

Note: To remove adapter, open door and slide out. To reinstall adapter, place
