1.18 How to Select a Pulselength
The pulselength in use appears at the upper-left position on the screen. The pulse-
lengths are set to each range scale and custom setup. You can change the pulse-
length on the 1.5 nm, 1.6 nm, 3 nm or 3.2 nm range with the following procedure.
Pulselength cannot be changed on other ranges. (You can change the pulselength on
the 2 nm or 4 nm range in the [Russian-River] mode.) Use a longer pulse when your
purpose is long range detection. Use a shorter pulse when the resolution is important.
Note: Press the CUSTOM key several times to activate the [Echo] menu until the [CS
1] (2, 3) indication (custom setting) disappears from the screen. See the illustration in
section 1.3.
