Under certain circumstances, it may be easier to adjust the display timing with MBS (Main Bang Suppression) off; press the MBS soft key to toggle the setting OFF. MBS is reset to ON automatically when you finish adjust- ing the display timing.

STC Preset

The Sensitivity Time Control can be adjusted to equalise targets levels across the display. The factory setting should provide an even display, but if you find that targets are brighter or dimmer nearer the centre than at the edge of the display, you can adjust this slider until the required display is achieved.

Note: Caution should be observed when adjusting this parameter as poor ad- justment can adversely affect auto gain and sea controls.

Tune Preset

The radar tuning is controlled either automatically or manually using the TUNE control (see Tuning the Receiver on page 3-9). However, this only controls a restricted range of tuning values. If the actual tuning peak falls outside this range, you will need to adjust the Tune Preset slider to move the controlled range over the tuning peak.

Press the INITIATE SET UP soft key to enable slider control, and adjust for maximum image intensity.

If required, you can press the RESTORE PREVIOUS soft key to reset the Tune Preset to the value before you pressed INITIATE SET UP.
