Signal Gain
When the self-check is complete, the display will indicate the last
signal gain (sensitivity) setting stored in the memory by flashing three
times and then remain on for
another three seconds. Here,
the unit has been set to a
relatively low gain level of 3.
The gain readout will
remain on for 3 seconds
then the display will go
dark.
The CD42-STS
receiver is now in the
operational mode and is looking for
electromagnetic pulses. To verify that
the unit is operating prior to deployment, bump the antenna with your
hand. The displays LEDs will jump and confirm it is operating.
Adjustment

Press and hold the control button momentarily to redisplay the current

gain level increases.
Each increment will
be set in 1.25-second
intervals.
After the gain control
reaches the full-scale position it will
cycle to the zero gain position. Keeping the button pressed will restart
the gain increase cycle.
