REPEATER OPERATION
■ Subaudible tones
for repeater use
Some repeaters require subaudible tones to be accessed.
Subaudible tones are superimposed over your normal signal
and must be set in advance.
➀ Push [VFO] to select VFO mode.
➁ Push [MULTI(↔)] to select a band.
➂ Push [MULTI] for 1 sec. to enter set
mode.
➃ Push [MULTI(↕)] one or more times
until “rT” appears.
➄ Push [MULTI(↔)] (or rotate (DIAL)
to select the desired subaudible
tone.
➅ Push [VFO] to enter the selected tone and exit set mode.
Available subaudible tone frequencies (unit: Hz)
67.0 79.7 94.8 110.9 131.8 156.7 171.3 186.2 203.5 229.1

■ Setting an offset
frequency
When communicating through a repeater, the transmit fre-
quency is shifted from the receive frequency by an amount
determined by the offset frequency.
➀ Push [VFO] to select VFO mode.
➁ Push [MULTI(↔)] to select a band.
➂ Push [MULTI] for 1 sec. to enter set
mode.
➃ Push [MULTI(↕)] one or more times
until “OW” appears.
➄ Push [MULTI(↔)] (or rotate (DIAL)
to select the desired offset.
• The offset frequency changes according to the selected tuning
steps.
• The MHz step may be helpful for large frequency changes—push
[(VFO)MHz] for 1 sec.
➅ Push [VFO] to enter the selected offset and exit set mode.
