12.Move the ShuttlePoint knob down to highlight MBS and adjust to 000 by moving the ShuttlePoint knob to the right.
13.Move the ShuttlePoint knob down to highlight TX TRIGGER DELAY and adjust moving the ShuttlePoint knob to the right to a point that the center looks as a solid circle as shown in the diagram below.
14.To save the TX Trigger Delay setting, move the ShuttlePoint knob down to Done and press [ENT].

Figure 3.1.0c - Adjusting Trigger Delay
MBS (Main Bang Suppression) Adjustment
(ONLY FOR MDS-9 DOME & MDS-10-4/MDS-10-5 OPEN ARRAY ANTENNAS)
The MBS is used to remove the echo closest to the vessel as shown in the right image in figure 3.1.0c. If Main Bang appears at the screen center (it looks like a as a circular dot) suppress it as follows:
1.Transmit on a long range about ten minutes.
2.Press [MENU]. Move the ShuttlePoint knob to highlight TUNING and press [ENT].
3.Move the ShuttlePoint knob to highlight TX TRIGGER DELAY and press [ENT].
4.Move the ShuttlePoint knob to highlight GAIN and press [ENT]. Adjust the Gain in such a way that the circular dot is clearly displayed.
5.Move the ShuttlePoint knob to highlight MBS and press [ENT]. Increase the MBS value until the circular dot is completely erased from the screen. Do not increase the MBS more than the value required to completely erase the main bang it otherwise you run the risk to suppress also target echoes.
3.1.1Automatic Tune (NOT NECESSARY AT FIRST INSTALLATION)
The Tune control is used to tune the receiver in the Radar antenna for maximum target returns on the display. The Radar comes from the factory already tuned so this operation is not necessary at first installation. In general Radar tuning may be necessary if the Radar antenna was serviced.
Automatic Tune
In Automatic Tune mode, the Radar tunes itself automatically on all range scales. It is recommended to execute the Tune function in Automatic mode. This generally ensures that the Radar receiver is always tuned to receive the maximum signal.
After the Radar Antenna is installed (or has been on the vessel for a year or longer) perform the Automatic Tune procedure, which adjusts the receiver Gain to show targets on all ranges.
