Preparing to use battery power

Figure 9

Optional operation switches

inside the battery compart-

ment

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

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.
