ETTING YOUR HEADSET READY FOR USE
Preparing to use battery power
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.

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, exist-
ing 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.
