How to Adjust 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 NM range, will appear
on the display as being pulled inward or pushed outward. See the figures below.
• The range of target echoes will also be incorrectly shown.
1. Set the controls as shown below:
GAIN: 80, STC: 0, RAIN: 0, FTC: OFF
2. Open the [MAIN]>[CONFIGURATION] menu.
3. Click [INSTALLATION] to show the [INSTALLATION] menu.
