■ FSK operation
The transceiver has FSK and J2B modes for FSK op-
eration— use F1B when using the built-in oscillator;
use J2B 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.
•FSK ITU channel group, Ch 4001 to Ch 25040, are only
available when SITOR CH setting is set to ON. (p. 49)
e
Push [MODE

] several times to select F1B or J2B.
r Operate the FSK terminal unit.
NOTE:
➥ FSK tone, shift frequency and FSK polarity can
be adjusted in initial set mode (p. 51)
➥ Some transceivers may operate 1.7 kHz higher
than the IC-M802’s J2B mode even when the
same displayed frequencies are in use.
