Gain

The Gain Adjustment allows the user to control the sensitivity of the
unit' s receiver. This provides some flexibility in what is seen on the display.
To see more detail, increase the receiver sensitivity by selecting a higher gain
(+). If there is too much detail or if the screen is cluttered, lowering the
sensitivity (-) may increase the clarity of the display.
To change the Gain:
1. Highlight 'Gain' on the Adjustment Bar.
2. Using the UP or DOWN Arrows, move the pointer to the desired setting.
