The icon is located under the Main menu. Select the icon one more time to close the menu.
Note
Immediately after you have turned on the ME70, the Operation icon is flashing. The icon is flashing to indicate that even if the ME70 system is turned on, "pinging" is disabled. The ME70 is in Passive mode to prevent transmission. This is for safety reasons.
Description
•  Operation
The Operation function controls the operating mode of the ME70 system. You can set it to Normal, Replay or Inactive.
•  Ping
The purpose of the Ping function is to enable or disable the ME70 transmissions into the water. Such transmissions are often referred to as "pinging".
•  Ping Mode
Use Ping Mode to control how often the ME70 shall transmit its energy into the water. For scientific operations, choose Interval, and select a Ping Interval value according to the survey requirements.
•  Ping Interval
The Ping Interval function is used when Ping Mode is set to Interval. The Ping Interval function permits you to choose the time (in milliseconds) between each transmission ("ping").
•  Record
Record allows you to record echo data. You can save the data to the hard disk, or onto an external storage device. The data files can be played back on the ME70 system. You can keep the recorded files for future reference, training purposes and calibration.
•  Tx Power
Use Tx Power to increase or decrease the output power. The output power is selected from predefined steps.
•  TX Mode
TX Mode is used for increasing and decreasing the frequency of transmitting acoustic energy (“ping”) into the water.
TX Mode can be set to active, which enables you to adjust the number of output pings, or passive in which case you cannot make these adjustments.
•  View Beam Mode
View Beam Mode enables you to see all settings for the current beam mode. It opens the Beam Mode dialog box
