Connector 10 - Loud hailer speaker
Number
Label
Description
1
HAILER SPK+
2
HAILER SPK-
Important: Do not short circuit these 2 pins, as it may cause damage
to the radio.
Install the hailer speaker in a forward-facing location on the boat.
This is because, in addition to transmitting foghorn sounds, the
hailer speaker ‘listens back’ when not transmitting.
¼
Note:
Use a 4-8 ohm speaker or loud hailer horn rated at no less
than 30 W. Higher impedance will reduce audio output volume.
