RECEIVE AND TRANSMIT

■ CW operation (Depends on versions)

The transceiver has the following CW keying features
selectable in the set mode, as described on page
15.
➥ Full break-in
(receiving is possible while transmitting)
➥ Semi break-in
➥ OFF
(manual transmission is necessary before keying)
q Connect a CW keyer or an external electronic
keyer to the ACC(1) socket, as shown at right.
w Select the desired channel to operate in the A1A
(CW) mode.
e When the selected channel is not in the A1A (CW)
mode, push [MODE] one or more times to select
"A1A."
r Operate the CW keyer to transmit a A1A (CW) sig-
nal.
NOTE:
A1A mode is not available in some versions.
•
CW narrow can be selected in the set mode when
•
an optional filter is installed. (p. 14)

■ FSK operation (Depends on versions)

The transceiver has FSK and J2B modes for FSK op-
eration—use FSK when using the built-in oscillator;
use J2B when using an AFSK terminal unit.
q Connect an FSK terminal unit as shown at right.
w Select the desired channel.
• FSK ITU channel group, ch 4001 to ch 25040, are
available, depending on the version.
e Push [MODE] one or more times to select either
"FSK" or "J2B."
r Operate the FSK terminal unit.
NOTE:
FSK shift frequency and FSK polarity can be ad-
•
justed in the set mode (pgs. 14 and 15).
Some transceivers may operate 1.7 kHz higher
•
than the IC-M710's J2B mode, even when the
same displayed frequencies are in use.
