GETTING YOUR HEADSET READY FOR USE Preparing to use battery power Figure 9 Optional operation switches inside the battery compartment The battery compartment on your headset control model serves two purposes. In addition to holding the batteries, it contains small switches (Figure 9) that give you the option to change some of the factory-set operation defaults for your headset. Refer to "Battery replacement" on page 28 for information on opening the battery compartment. AUT ON C & K S006 123456 Changing the optional operation switches Note: To change switch positions, use a pen or a small, flat-tipped screwdriver to gently switch the tab. • Switches 1- 3: Not currently used. • Switch 4: Set at the factory to enable the smart shutoff function. To disable smart shutoff, set switch to OFF. With the switch in OFF position, the ANR system will not turn off until the power button is depressed and held for at least one second. Note: The smart shutoff function is designed to detect when the headset is not in use and shut off ANR to preserve battery power. Smart shutoff turns off circuitry several minutes after you remove the headset. • Switch 5: Set to A at the factory for operation with new headsets. Set it to B if you are installing a portable cable onto an older, existing Aviation Headset that was manufactured before June, 2003. Note: If you cannot determine the manufacture date of your headset, refer to "Locate the serial number for your product registration card" on page 10. • Switch 6: Set at the factory for mono audio systems (to provide audio in both ears). Set it for stereo (ST) if your aircraft has a stereo intercom. 13
