Adjusting the output power to match varying conditions
You are permitted to adjust the output power from the ME70 system. Tx Power is used to control the amount of power that is transmitted with each ping.
Context
Most users operate the ME70 system with Tx Power set to Maximum. This allows for maximum range, and works well in open waters with sufficient depth. Certain operating conditions may make it appropriate to adjust the output power. Use Tx Power to reduce the transmitted acoustic energy compared to the maximum output.
Sea conditions vary, sometimes drastically. The acoustic conditions are also changing. Temperature and salinity layers differ from one day to the next, and from one position to another. It is not possible to identify settings that will provide the best data at all times.
Procedure
1 Open the Operation menu.
2 Select Tx Power.
