Understanding Receiver LEDs
Boot sequence
When you power on the receiver, the LEDS on the receiver must light up the following way:
• Hydrophone LEDs become blue / red / green.
• LED in the letter A becomes blue / green / red, then stays red.
• When data are emitted or received, ETH LED blinks green.
Hydrophone LEDs
The LEDs on the hydrophone inputs identify the type of hydrophone that is connected to the
receiver.
• Blue: passive hydrophone
• Red: active hydrophone
• No light: no configured hydrophone
