3. ADJUSTMENTS

3.1 Installation Check

After installing the system it is a good idea to check it for proper installation, following the checklist provided below.

•Cable gland is facing toward the stern.

•Four fixing bolts securing the antenna unit are securely tightened.

•The antenna cable is waterproofed at the base of the antenna unit.

•The antenna cable is securely retained against the mast or mounting and is free of interference from running rigging.

•The cable gland on the deck or bulkhead is waterproofed, if provided.

•Connectors of external equipment are securely plugged into the radar display unit.

•The power connections to the battery are of correct polarity.

3.2Exchanging Display Unit of Previous Model

When exchanging the display unit of the MODEL 1621/1621 MARK-2 with that of the MODEL 1622, it is necessary to maintain the magnetron warmup time. This should be done with the radar in stand-by.

1.Press ▲ and ▼ together for about 10 seconds to show the display shown in Figure 19.

2.Select MODEL by ▲.

M1622: 1 minute.

M1621/M2: 1minute and 30 seconds.

3.Select M1621/M2 by 4.

4.Press the [MENU] key to close the menu.

3.3 Adjustments

Do the following in order to adjust the radar.

1) Adjustment of picture

1.Press the [POWER] key on the display unit. The display should light. In approximately one minute, ST-BY appears at the screen center.

2.When ST-BY appears press the [TX] key. The radar will start transmitting, and you will probably see some targets, even though the radar is not yet properly adjusted.

3.Adjust the sensitivity to display a small amount of noise on the screen.

4.Press the [–] key several times to select the minimum range. Adjust the STC to display nearby radar targets clearly on the screen. Too much STC action will eliminate small targets, and too little STC action will cause the screen to be so full of targets and noise that it is hard to determine which target is which as compared to visual sightings.

2) Heading alignment

You have mounted the antenna unit facing straight ahead in the direction of the bow. Therefore, a small but conspicuous target dead ahead visually should appear on the heading mark (zero degrees).

In practice, you will probably observe some small error on the display because of the difficulty in achieving accurate initial positioning of the antenna unit. The following adjustment will compensate for this error, up to ±30 degrees.
