LOW VARIABLE GAIN SETTINGS CAN ELIMINATE HAZARDOUS
TARGETS FROM THE DISPLAY.
In GMAP mode, variable gain is used to reduce the level of strong
returns from ground targets.
Minimum gain is attained with the control at its full ccw position. Gain
increases as the control is rotated in a cw direction from full ccw at full
cw position, the gain is at maximum.
The VAR! legend annunciates variable gain. Selecting RCT or TGT
forces the system into calibrated gain.
9 SLV (Slave)
The SLV annunciator is only used in dual controller installations. With
dual controllers, one controller can be slaved to the other by selecting
OFF on that controller only, with the RADAR mode switch. This slaved
condition is annunciated with the SLV annunciator.
In the slaved condition, both controllers must be off before the
radar system turns off.
10 LSS (Lightning Sensor System) (Option)
The LSS switch is an optional four- position rotary switch that selects
the LSS operating modes described below:
OFF - In this position all power is removed from the LSS.
D
SBY - In this position the display of LSS data is inhibited, but the LSS
D
still accumulates data.
LX - In this position the LSS is fully operational and it displays LSS
D
data on the indicator.
CLR/TST - In this position, accumulated data is cleared from the
D
memory of the LSS. After 3 seconds the test mode is initiated in the
LSS.
