(2) Press the [VFO], [MR] or [CALL] key to switch to the

frequency display.

(3) Turn the encoder to display the upper limit frequency on

the LCD.

(4) Repeat steps (4) to (7) of ”113.8V TX L power (Lower limit

frequency)” described on page 32.

L. DCS modulation balance
(1) Press the [LAMP] or [MONI] key on the transceiver to display

“DCS.BAL” on the LCD. Press the [F] key and then the
[PTT] key repeatedly to turns the “

” icon ON.

(2) When the [PTT] key is pressed to enable transmit mode, a

100Hz square waveform is internally generated and
modulated.

(3) While observing the waveforms on the oscilloscope, turn

the semi-fixed volume (VR6) to adjust the DCS modulation
waveform to a square waveform.

(4) When the DCS modulation waveform becomes a square

waveform, release the [PTT] key.

M.Tone deviation (Lower limit frequency, center

frequency, upper limit frequency)

1Tone deviation (Lower limit frequency)
(1) Press the [LAMP] or [MONI] key on the transceiver to display

“DVL” on the LCD.
In this case, the “

” icon appears. Press the [F] key and

then the [PTT] key repeatedly to turn the “

” icon ON.

The current adjustment value is displayed at the lower digits
of the frequency display, and the value stored in the
EEPROM is displayed on the memory channel number
display.

(2) Press the [VFO], [MR] or [CALL] key to switch to the

frequency display.

(3) Turn the encoder to display the lower limit frequency on

the LCD.

(4) Press the [CALL] key to switch to the adjustment display.
(5) When the [PTT] key is pressed to enable transmit mode, a

preset tone frequency (151.4Hz) is internally generated and
modulated.

(6) Turn the encoder to change the current adjustment value

and adjust tone deviation.

(7) Press the [MENU] key to write the current adjustment value

into the EEPROM.

2Tone deviation (Center frequency)
(1) Press the [LAMP] or [MONI] key on the transceiver to display

“DVC” on the LCD.
In this case, the “

” icon appears. Press the [F] key and

then the [PTT] key repeatedly to turn the “

” icon ON.

(2) Press the [VFO], [MR] or [CALL] key to switch to the

frequency display.

(3) Turn the encoder to display the center frequency on the

LCD.

(4) Repeat steps (4) to (7) of ”1Tone deviation (Lower limit

frequency)” described on page 33.

3Tone deviation (Upper limit frequency)
(1) Press the [LAMP] or [MONI] key on the transceiver to display

“DVH” on the LCD.
In this case, the “

” icon appears. Press the [F] key and

then the [PTT] key repeatedly to turn the “

” icon ON.

(2) Press the [VFO], [MR] or [CALL] key to switch to the

frequency display.

(3) Turn the encoder to display the upper limit frequency on

the LCD.

(4) Repeat steps (4) to (7) of ”1Tone deviation (Lower limit

frequency)” described on page 33.

N. DCS deviation (Lower limit frequency, center frequency,

upper limit frequency)

1DCS deviation (Lower limit frequency)
(1) Press the [LAMP] or [MONI] key on the transceiver to display

“DVL” on the LCD.
In this case, the “

” icon appears. Press the [F] key and

then the [PTT] key repeatedly to turn the “

” icon ON.

The current adjustment value is displayed at the lower digits
of the frequency display, and the value stored in the
EEPROM is displayed on the memory channel number
display.

(2) Press the [VFO], [MR] or [CALL] key to switch to the

frequency display.

(3) Turn the encoder to display the lower limit frequency on

the LCD.
