Checking and/or editing the transceiver parameters
For Normal operation mode to run, the output transmission pulse must be defined. This is done using Beam mode, Ping Mode, Ping mode transmission mode and power You can change the parameters.
Prerequisites
This procedure assumes that the ME70 system is turned on and operates normally.
Procedure
1 On the Main menu select Beam Mode. By clicking the middle button a list of available beam modes appears. Select the appropriate mode.

2 On the Operation menu, select Operation. By clicking the Operation button a list of available operational modes appears. Select Normal mode

3 Select Ping Mode on the Operation menu.
The “ping rate” is the parameter that controls how often the echo sounder shall transmit acoustic energy (a “ping”) into the water. When transmission is enabled, you can choose from these ping modes: Single Step, Interval and Maximum. Single step allows you to send a single transmission at a time, while Interval is used for specifying a specific interval between each ping. If you select maximum, the system will transmit continuously.

4 Select transmission power, Tx Power, on the Operation menu.

Whenever active transmissions take place, you can adjust the power output by means of Tx Power.
5 Select transmission mode, Tx Mode, on the Operation menu.
Image
Passive transmission mode enables the system to listen to received echo data, but not transmit. This is if pinging is enabled (Ping set to On). You can use this mode to detect and investigate background noise. If pinging is switched off the system will not transmit nor receive. If the Tx Mode is set to active the system will be able to transmit (if Ping is set to On).
6 If you have selected Interval as ping mode and want to transmit with fixed time intervals. select Ping Interval. Specify the interval between each ping using the button.
