7.7 Background selection lockout
To prevent accidental selection or tampering, the
background menu option can be disabled using a
mechanical switch located behind the Aurora H2O display.
Access to the switch requires removal of the cover, and
should be performed only in non-hazardous conditions.
NOTE: Unless otherwise requested, the Aurora/H2O is
shipped with the background selection unlocked.
The lockout switch is positioned to the right of the laser
indicator (see Figure 101 below). When the switch is in the
up position, the background selection menu is unlocked.
When the switch is in the down position, the background
selection menu is locked.
