1.12 Selecting the Range Scale
The display range scale is changed by pressing the [+] and [-] keys. The selected range scale and
range ring interval are shown at the upper left corner on the screen. When a target of interest
comes closer, reduce the range scale so that it appears in 50-90% of the display radius. The range
scales are 0.125-0.25-0.5-0.75-1.5-3-6-12-24-48-96 nm.
Press the [RANGE] key to select range. The range, range ring interval and pulselength appear at
the top left corner of the display.
1.13 Selecting the Pulselength
The pulselength in use is displayed at the upper-left position. Appropriate pulselengths are preset
to individual range scales and function keys. Therefore, you are not usually required to select them.
If you are not satisfied with the current pulselength settings, however, it is possible to change them
by the ECHO SIG menu as below. The pulselength is selectable on the ranges 0.5 to 24 nm.

1.13.2 Presetting pulselengths 1 and 2
Pulselength 1 and 2 can be preset on the PULSE 1 and PULSE 2 in the ECHO SIG menu. A
longer pulse provides an increased detection range, but with reduced discrimination. If you need
discrimination in preference to detection, choose a shorter pulse. However short the radar satisfies
the detecting requirements of the IMO.
1. Press the [MENU] key.
2. Press the [5] key twice to display the ECHO SIG menu.
3. Press the [6] or [7] key as appropriate to select PULSE 1 or PULSE 2.
4. Press appropriate numeric key among 2-7 to select pulselength and range.
5. Press the [ENTER/SELECT] key.
