e Push [VFO] to exit DTMF memory.
r Set the receive frequency (repeater output frequency).
t Set the shift direction of the transmit frequency. (–DUP or
DUP; see p. 31 for details.)
y While pushing [PTT], push [SQL] for 1 to 2 sec. to transmit
a 1750 Hz tone burst signal.
• If “OFF” appears, check the offset frequency or shift direction.
(p. 31)

frequency (repeater input frequency).
