RECEIVE AND TRANSMIT
• CW operation
(Marine/General versions only)
The transceiver has the following CW keying fea-
tures and they can be selected in set mode as
described on p. 14
• Full break-in (receiving is possible while transmitting)
• Delay keying (automatic transmission with keying)
• OFF (manual transmission is necessary before keying)
CD
Connect a CW keyer or an external electronic
keyer to the ACC(1) socket as shown at right.
(g) Select the desired channel to operate CW mode.
@ When the selected channel is not in A1A mode,
push [MODE] one or more times to select "A 1
A."
@ Operate the CW keyer to transmit a CW signal.
~
CW mode may not be used depending on versions.
~
CW narrow can be selected in set mode (p. 13) when
~ an optional filter is installed (already built-in to the
GMDSS
~
versions).

• FSK operation
(Marine/General versions only)
The transceiver has FSK and J2B modes for FSK
operation. Use the FSK mode when using the
oscillator in the transceiver and use the J2B mode
when using an AFSK terminal unit.
CD
Connect an FSK terminal unit as shown at right.
(g)
Select the desired channel.
- FSK ITU channel group, ch 4001 to ch 25040, are
available depending on versions.
@ Push [MODE] one or more times to select the
type of emission as "FSK" or "J2B."
@ Operate the FSK terminal unit.
~ FSK shift frequency and FSK polarity can be adjusted
~
in set mode (pgs. 13, 14).
NOTE: Some transceivers may operate 1 .7 kHz higher
than the IC-M71 O's J2B mode even when the same
displayed frequencies are in use .

• Cross channel operation
(Europe versions only)
Cross channel operation is available with some
versions to operate different channels for receiving
and transmitting.
CD
Select the desired channel for receiving.
- ITU simplex channels cannot be used for cross
channel operation.
(g)
Push
[TX], then select the desired channel for
transmitting.
- "ID"
blinks after pushing [TX].
@ Push
[TX]
again to stop the blinking.
@ Operate the transceiver normally.
