RECEIVE AND TRANSMIT
To search for a repeater’s sub-audible tone, a tone
scan is available.
By monitoring a repeater signal with a tone squelch,
you can determine the tone frequency necessary to
open the repeater or the squelch.
q
In the FM mode, push [MENU] to display the “M1”
screen (Menu 1).
w
Hold down [TON](F-4) for 1 second to enter the
“TON” screen (Tone).
e
Push [TON](F-1) one or more times to select the
tone type to be scanned.
• “Rptr Tone” for a repeater tone and “TSQL Tone” for
tone squelch can be selected.
r
Push [SCAN](F-2) to start the Tone scan.
• “Rptr Tone SCAN” or “TSQL Tone SCAN” blinks, de
-
pending on the type you selected.
t
When a matched tone is found, the scan pauses
and the sub-audible tone frequency is automatically
programmed.
• Hold down [F-3] for 1 second to reset to the default set
-
ting, if desired.
y
Push [SCAN](F-2) to cancel the Tone scan.
When the tone scan is used in the Memory channel
mode, the detected tone frequency can be used
temporarily.
To save the detected tone frequency setting, you
must over-write the Memory channel data. (p. 70)

Tone scan operation
Repeater operation
A repeater receives transmitted signals and re-trans-
mits them on a different frequency. When using a re-
peater, the transmit frequency is shifted from the re-
ceive frequency by a frequency offset.
A repeater can be accessed using the split frequency
operation to set the frequency shift to the same value
as the repeater’s frequency offset.
q
First, set the frequency offset for the HF and 50
MHz bands in the “FM SPLIT Offset HF” and “FM
SPLIT Offset 50M” items, and set the “Quick SPLIT”
item to “ON” in the Set mode. (p. 86)
w
Push [VFO/MEMO] to select the VFO mode.
e
Select the desired band. (p. 25)
r
Push [AM/FM] to select the FM mode.
t
Rotate [DIAL] to set the receive frequency (repeater
output frequency).
y
Hold down [SPLIT] to turn ON the Quick Split func-
tion.
• “
” and “TONE” appear.
• The tone frequency can be set in the “TON” screen
(Tone). 88.5 Hz is set by default. (p. 52)
