Using the hailer with talk-back
While in hailer mode the hailer can also be used as a
microphone. For details how to set the talk-back mode see
Hailer and Fog horn setup
on page 47. Once set up talk-back
is activated when you are in hailer mode and the PTT button is released.
When talk-back is active your crew can talk to you via the loudhailer horn
unit into the loudspeakers. The talk-back volume can be independently
adjusted on the volume knob while talk-back is active (TB Volume). If a
signal is received on the radio while in talk-back mode, the received radio
signal will be heard in the speakers. The received radio signal will be
reproduced with the normal volume level.
Important
When the hailer is in talk-back mode and a radio signal is
received, the radio signal has a higher priority and is heard in
the loudspeaker.
