COMMUNICATING AIDS 5 Operation in Narrow FM Mode It is possible to switch to a narrow bandwidth during operation in the FM mode. The occupied bandwidth and maximum modulation factor are shown in the table below. Selecting FM Narrow according to the modulation factor of the target station helps to avoid distortion and deterioration in the clarity of the RX audio. Mode FM (Wide) FM Narrow Occupied Bandwidth 16 kHz or lower 10 kHz or lower Maximum Modulation Factor ±5 kHz or lower ±2.5 kHz or lower Press and hold [FM/AM]. Pressing and holding [FM/AM] each time switches between "FM" and "FMN (Narrow)".

Operation in Narrow FM Mode
It is possible to switch to a narrow bandwidth during operation in
the FM mode. The occupied bandwidth and maximum modulation
factor are shown in the table below. Selecting FM Narrow
according to the modulation factor of the target station helps to
avoid distortion and deterioration in the clarity of the RX audio.

Configuring the Tone Signal
●
Registering the tone settings to a memory channel and
calling up the frequency or operation information from
the memory channel eliminates the need to configure the
tone frequency each time. For more details on the
memory channel settings, please refer to “
MEMORY
CHANNELS
” (
9-1
).
●
The tone frequency may vary depending on the country
or region this transceiver is being used.
Selecting a Tone
Press F4 [TONE] to select “TONE”.
Pressing
F4 [TONE]
each time toggles the tone signal selection
in the following sequence: “TONE” → “CTCSS (CT)” →
“CROSS” → Blank (deselected).
Configuring the Tone Frequency
1
Press and hold F4 [TONE] while “TONE” is selected
to display the FM Tone Frequency screen.

Tone Frequency Scan
Tone frequency that is contained in signals received in the FM
mode can be searched and displayed with the following steps. This
is useful when there is a need to know the tone frequency of the
repeater station.
1
Press and hold F4 [TONE] while “TONE” is selected

•
Scanning stops when a tone frequency is detected, and the
frequency is displayed in the “FREQ. [Hz]” field.
•
Pressing
F7 [SCAN]
while tone frequency scan is in
progress stops the scan operation. Pressing
F7 [SCAN]
again resume scanning.
•
The scan operation stops when the RX signal is interrupted
during tone frequency scan. Scanning resumes when a RX
signal is detected by this transceiver.
