Table 6 lists the possible configured and corresponding alternate display states of the Status LED.
Table 6: Setting and alternate display states of the Status LED.
Configured State Alternate State
ON (SWITCHABLE) OFF
ALERTS ONLY (SWITCHABLE) ON
OFF (NON-SWITCHABLE) OFF
OFF (SWITCHABLE) ON
Note that state changes can occur only between options in the same rows of the table above. For
example, it is possible to toggle the state back and forth between ALERTS ONLY and ON, but not
between ALERTS ONLY and OFF. Transitioning from ALERTS ONLY to OFF would require
changing the LED mode setting in BC|Commander.
The default LED Mode for the LX4 is OFF (switchable).
Note
As of firmware release 10.16, there are two different configurable OFF states: Off
(switchable), which toggles to ON, and Off (non-switchable), which has no alternate
state. If the LED Mode is set to OFF (non-switchable) in BC|Commander, the
Configuration Switch will NOT turn it on.
Warning
The LED remains active until the completion of the boot process. The LED may
display information during the boot process unless the LED mode is set to OFF. The
LED must be physically masked (such as adding tape to the LED lens) to guarantee
that no light is emitted at any time.
1.3.6.2 Zeroize Keys and Restore Factory Defaults
This mode is is used to erase the security protocol keys of a BreadCrumb LX4 and to restore its
software configuration to the factory default state. To operate this switch follow these procedures:
● Ensure that the BreadCrumb is powered on, has fully booted-up and its Status LED color is
green or blue (see Table 5).
● Press the switch and hold the switch for approximately 10 seconds until the Status LED
changes to blinking yellow. This indicates that the Zeroize Keys and Restore Factory
Defaults operation has been initiated and is in progress.
● Release the switch. The Status LED should change to display the blinking red error code 32.
See Appendix A for a description of the blinking red color sequence. The BreadCrumb will
then reboot using the factory default configuration.
