When the system menu is not displayed, pressing either side
of the GAIN/EL rocker switch calls up the gain control scale.
The gain control scale is presented in the eyepiece display
as shown in Figure 2-9.
Figure 2-9. Gain Control.
The gain control setting is adjusted by pressing the + or -
sides of the GAIN/EL rocker switch to move the status bar
between the left and right ends of the scale. Repeatedly
pressing the + or - buttons will move the status bar in single
increments. Pressing and holding the + or - buttons will
auto-scroll the status bar in multiple increments.
If the + or - buttons are not pressed within 3 seconds, the
gain control scale will disappear and the LWTS will revert to
normal viewing mode. Once adjusted, gain will remain at the
applied setting until readjusted by the operator or the system
reset feature is initiated.
