Detailed Operating Instructions
This section provides instructions on how to use the system and its functions.
4.3.1
Menu (<MENU>)
The <
MENU
> key is used to access the setup capabilities of the Model 8011M. In general, when an item
is selected in a menu, either that item is chosen or a value will need to be entered or adjusted up and
down. To select an item, press the number key associated with that parameter. For example, when
<
MENU
> is selected, one can change the system set up by pressing the <
3
> key.
Pressing a key will either bring up a sub-menu or allow changing a value by entering a number or toggling
through choices. Once the value is entered and <
ENT
> is pressed, the menu moves back up one level.
There are three main items:
Command Setup, Range Setup,
and
System Setup.

There are four choices in the Command Setup menu:
1.
EdgeTech/ORE

4.3.1.2
Range Setup
There are six choices in the Range Setup menu:
1.
The Interrogate frequency allows the user to change the frequency that the 8011 M transmits to
the underwater unit. The value can be from 7.5 kilohertz to 15.0 kilohertz in 500-hertz steps.
2.
Reply frequency is used for setting the frequency that the 8011M will receive as a valid reply from
the underwater unit. The value can be from 7.0 kilohertz to 15.0 kilohertz in 500-hertz steps.
3.
Turnaround time is the internal delay in the underwater unit being used for the ranging operation.
This is the time from when the pulse arrives at the underwater unit to when the underwater unit
transmits in response. This time is subtracted from the total round-trip travel time when
calculating ranges. The turnaround time can be set from 0 to 1 second in 1 millisecond increments.
