2.6.1 LED Configuration
This mode is used to control the display states of the Status LED. The LED Configuration function is
accessed by pressing the button and releasing it after a two second hold. The display state of the Status
LED, or
LED Mode,
is configured from BC|Commander (please refer to the BC|Commander 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 button and activating the LED
Configuration function.
Table 2 lists the possible configured and corresponding alternate display states of the Status LED.

states:

, which toggles to
On
,
and
Off
, which has no alternate state. If the LED Mode is set to
Off
, the LED
Configuration Button will NOT turn it
On
.
