How to record echo data

To start data recording, click the [Echo Recording] menu icon from the InstantAccess
bar™, then click the [Record] icon. To stop the recording at any time, click the [Stop]
icon.
The amount of memory used for recording echo data varies, depending on configura-

sion and the range set to 150 m, the estimated memory usage is 4.7 GB per hour.

for this function.

icon is not selectable.
