The transceiver has the following CW keying features
selectable in set mode as described on p. 43.
➥ Full break-in
(receiving is possible while transmitting)
➥ Semi break-in (automatic transmission with keying)
➥ OFF (manual transmission with microphone’s [PTT], or
grounding the SEND line of [ACC] connector is
necessary before keying)
q Connect a CW keyer or an external electronic
keyer to the [ACC] socket as shown at right.
w Select the desired channel to operate CW mode.
e If the selected channel is not in CW mode, set to
select ‘CW.’ (p.18)
r Operate the CW keyer to transmit a CW signal.

The transceiver has FSK and AFSK modes for FSK
operation— use FSK when using the built-in oscilla-
tor; use AFSK when using an AFSK terminal unit.
q Connect an FSK terminal unit to the [ACC] socket
as shown at right.
w Select the desired channel to operate FSK mode.
e Push [I/O] to enter the Quick set mode.
r Push [

] several times to select ‘MODE,’ then
push [

CLR] or [OK
≈≈
] to select FSK or AFSK
mode.
t Operate the FSK terminal unit.
NOTE:
• FSK tone, shift frequency and FSK polarity can be
adjusted in initial set mode (pgs. 42, 43)
• Some transceivers may operate 1.7 kHz higher
than the IC-F7000’s AFSK mode even when the
same displayed frequencies are in use.
