Clear Memory Screen
When at the Main Screen, press the TAB key four times and the Clear
Memory Screen will appear.
CLR MEM?00000000
The Clear Memory option can be used to delete time-stamped studies that
have been stored in memory. However, to prevent studies from being accidently deleted, you are required to confirm that you want to clear the
memory. Press the DO key and the screen shown below will appear.
CLR? N
00000000
On this screen, the 'N' means No, do not clear memory. If you press DO at
this point, the Echo will cancel out of the memory clear process and return
to the Main Screen. Press TAB instead, and the screen shown below will
appear.
CLR? Y
00000000
On this screen, the 'Y' means Yes, do clear memory. If you press DO at this
point, the Echo will clear all stored time-stamp studies from memory and
return to the Main Screen.
Sensitivity Screen
When at the Main Screen, press the TAB key five times and the Sensitivity
Screen will appear.
Sen:Def
00000000
The Sensitivity option can be used to select how sensitive the acoustic sensor
should be when recording data. The initial setting, Def, stands for Default
and will work fine for most applications. However, if you install the Echo
at a location where it appears to be overcounting due to extraneous noise,
or undercounting due to its distance from the vehicle sounds, this setting
can be used to make adjustments.
