3.4 Adjustment Sweep Timing

Sweep timing differs with respect to the length of the signal cable between the antenna unit

and the processor unit. Adjust sweep timing at installation to prevent the following

symptoms:

• The echo of a “straight” target (for example, pier), on the 0.25 m range, will appear on the

display as being pulled inward or pushed outward. See Figure below.

• The range of target echoes will also be incorrectly shown.

(1) Correct (2) Target pushed (3) Target pushed

inward outward

Examples of correct and incorrect sweep timings

1. Transmit on the 0.25 nm range.

2. Adjust radar picture controls to display picture properly.

3. Select a target echo which should be displayed straightly.

4. Press the [4] key to choose the [TIMING ADJ] on the [ECHO ADJ] menu.
