Setting a blanking area

When the antenna is installed at a close dis- tance in front of the wheelhouse, the radar should be set not to transmit within that area. No echoes appear in the blanking areas.

1.Select "7. Dead Sector".

2.Press the [ENTER] key.

3.Operate the omnipad to enter starting point of area (in figures).

4.Press the [ENTER] key.

5.Operate the omnipad to enter ending point of area (in figures).

6.Press the [ENTER] key.

Area of no transmission

Figure 6-27 Blank areas where

transmission is suspended

This area can be turned on/off on the OTHER MENU. For detail, see the description on page 18.

Note: This setting should be done after other adjustments are finished.

Magnetron heater voltage

Magnetron heater voltage is formed at the MD Board of the antenna unit and preadjusted at the factory for use with any length of signal cable. Therefore no adjustment is required. However, verify heater voltage by following the procedure below.

1.Turn on the radar (if it is not already on) and set it in stand-by.

2.Open the antenna housing (radome) cover. Connect a multitester, set to 10 V DC range.
