● Zeroize Keys and Restore Factory Defaults
2.7.1 LED Configuration
This mode is used to control the display states of the Status LED. The LED Configuration function is
accessed by pressing the switch and releasing it after a two second hold. The configured display state of
the Status LED is dictated by the LED Mode setting that is configured from BC|Commander (please
refer to the BC|Commander v11 User Guide for a more detailed description of the LED Mode setting).
The user can toggle between the configured state and an alternate state of the Status LED by pressing the
switch and activating the LED Configuration function.
Table 2 lists the possible configured and corresponding alternate display states of the Status LED.
Table 2: Configured and Alternate Display States of the Status LED
Configured State Alternate State
On Off
Alerts Only On
Off (non-switchable) N/A
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 ME4 is On.
Note
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), the Configuration Switch will NOT turn it on.
2.7.2 Zeroize Keys and Restore Factory Defaults
This mode is is used to erase the security protocol keys of a BreadCrumb ME4 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 1).
● Press and hold the switch for approximately 10 seconds until the Status LED changes to blinking
yellow (see Table 1). This indicates that the Zeroize Keys and Restore Factory Defaults
operation has been initiated and is in progress.
