European Operation: In Europe, a 1750 Hz tone
is generally used to access repeaters.
Select the Subtone frequency you require via Menu
No. 57 (SUB.TONE). The available choices are
shown in the table.
Continuous or Burst Subtones?
In addition to selecting the frequency of the Subtone,
you must choose the correct Subtone duration. The
Continuous selection sends the Subtone
continuously as long as the transceiver is
transmitting. The Burst selection sends a 500 ms
Subtone burst each time the transceiver begins
transmitting.
Select either Continuous or Burst via Menu No. 58
(SUB.TONE). The default is Continuous. This
selection cannot be stored in a memory channel.

Repeater frequency pairs (input/output):
29520/29620, 29540/29640, 29560/29660,
29580/29680
This completes the “FM TRANSMISSION” section.
Refer to “OPERATING AIDS” beginning on page 44 for
information about additional useful functions for
operating.

6 Select the receive frequency.
7 Press [TX B] (or [TX A]) to select split operation.
This must be the same VFO as selected in
Step 1.
The Tone function automatically switches ON.
8 Select the Subtone frequency via Menu No 57
(SUB.TONE) and Menu No. 58 (SUB.TONE).
See “Selecting Subtone Frequency” and
“Continuous or Burst Subtones?” for more details
on the Subtone.
To store data selected in Steps 1 ~ 8 in a memory
channel:
9 Press [M.IN].
10 Turn the M.CH/VFO.CH control to select a channel
(excluding channel 99).
11 Press [M.IN].
To send a Subtone that is stored in memory:
12 Press [RX M.CH].
13 Turn the M.CH/VFO.CH control to select the
channel.
14 Press [PTT] or [SEND].
Note:
When operating through a repeater, over deviation caused by
speaking too loudly into the microphone can cause your signal to
“talk-off” (break up) through the repeater.
When Subtones can be transmitted, “TONE” lights on the
Display.
Memory Transfer does not copy the stored Subtone frequency
data to the VFO.
The Subtone transmitted is the tone associated with the memory
channel or the VFO frequency that is used for the transmit
function. When you transmit using a VFO frequency or the
channel 99 frequency, the Subtone selected via Menu No. 57
(SUB.TONE) and Menu No. 58 (SUB.TONE) will be used;
however, when transmitting using a memory channel, the
Subtone stored in that channel will be transmitted.
Selecting Subtone Frequency
Some 10-meter FM repeaters use CTCSS
(Continuous Tone Coded Squelch System) to
prevent other repeaters on the same frequency from
keying thus locking each other up. This repeater
access system is also referred to as Tone or PL
(“Private Line”). If CTCSS is used by a repeater in
your area, set the Subtone frequency. The default is
88.5 Hz.
