OTHER FUNCTIONS
■ Hailer operation
The IC-M601 has a 2-way hailer function for voice amplifica-
tion and reception over a loudspeaker, making it unnecessary
to leave the bridge to hear a hailing party.
Connect an external hailer speaker (25 W or more/4Ω) as de-
scribed on p. 41.
• Transmitting is not possible during hailer operation.
• The received signal is muted during hailer operation.
q Push [F], then push [7 HAIL] to enter hailer mode.
w Push and hold [PTT] and speak at a normal voice level into
the microphone.
• “TALK” or “LISTEN” appears on the caller or listener function dis-
play, respectively.
• To adjust the hailer level, rotate [CHANNEL].
e After releasing [PTT] you can hear the response through
the speaker.
r
To return to normal operation, push [CLR] or repeat step q.
• While in the hailer mode, the transceiver functions (trans-
mit and receive) are interrupted. If the transceiver is in
transmit condition, the hailer function is not available.
•When a DSC call is received, the hailer function is inter-
rupted with an automatic return to the transceiver mode.
The transceiver’s display indicates ‘Receiving DSC calls.’
