Important:
Do not short circuit these 2 wires. Install the hailer horn in a forward-facing loca-
tion on the boat because the hailer horn will transmit the FOG horn sounds and will ‘listen
back’ when not transmitting.
Note:
We recommend you use a hailer horn of 4 Ohms to obtain maximum 30 W audio
output power.

You can connect 1 x 2 W 8Ω or 1 x 4 W 4Ω speaker to the 3.5 mm speaker connector.
