ADJUSTMENT

6. Upper limit frequency transmission output setting.

(1)Set the upper limit frequency and press the

microphone PTT button to enter transmit mode.

(2)Adjustment the power meter to the prescribed

transmission power by turning the encoder.

(3)When the specified transmission power value is

reached, release the microphone PTT button and
press the

[FREQ3]

key to set the adjustment value.

D. Transmission deviation

(values set independently for 144MHz and 430MHz)

1. Press the

[

]

and

[

]

keys to display “MAX DEV”.

The current transmission deviation setting is display on
the screen. (See the figure below.)

2. Connect the direct wave detector and power meter to

the ANT terminal, apply the prescribed A.G. input from
the MIC input terminal, and transmit.
Turn the

[ENCODER]

knob to adjust the direct wave

detector reading to the prescribed value.

3. W h e n t h e p r e s c r i b e d v a l u e i s r e a c h e d , s t o p

transmission and press the

[SET]

key to set the

adjustment value.

E. DCS modulation balance

(values set independently for 144MHz and 430MHz)

1. Press the

[

]

and

[

]

keys to display “DCS

BALANCE”.
The current DCS modulation balance setting is display
on the screen. (See the figure below.)

2. Connect the linear detector and oscilloscope to the

antenna connector. Connect a microphone to the
microphone connector.

3. When the microphone PTT button is pressed to enter

transmit mode, 50Hz square waves are internally
generated and modulated.

4. While observing the oscilloscope, turn the encoder to

adjust the DCS modulation waveform to square
waveform.

5. When the DCS modulation waveform becomes square

waveform, release the microphone PTT button and
press the

[SET]

key to set the adjustment value.

F. Tone deviation

(values set independently for 144MHz and 430MHz)

1. Press the

[

]

and

[

]

keys to display “TONE DEV”.

The current Tone deviation setting is display on the
screen. (See the figure below.)

2. Connect the linear detector and oscilloscope to the

antenna connector. Connect a microphone to the
microphone connector.

3. When the

[T.SEL]

key is pressed, the tone frequency

setting mode is entered, so set a tone frequency to be
adjusted by turning the encoder.

4. The microphone PTT button is pressed to enter

transmit mode.

5. Connect the direct wave detector and power meter to

the ANT terminal, apply the prescribed A.G. input from
the MIC input terminal, and transmit.
Turn the

[ENCODER]

knob to adjust the direct wave

detector reading to the prescribed value.

6. When the prescried value is reached, stop transmission

and press the

[SET]

key to set the adjustment value.

G.DCS deviation

(values set independently for 144MHz and 430MHz)

1. Press the

[

]

and

[

]

keys to display “DCS DEV”.

The current DCS deviation setting is display on the
screen. (See the figure below.)

2. Connect the linear detector and oscilloscope to the

antenna connector. Connect a microphone to the
microphone connector.

3. When the

[T.SEL]

key is pressed, the tone frequency

setting mode is entered, so set a tone frequency to be
adjusted by turning the encoder.

4. The microphone PTT button is pressed to enter

transmit mode.

5. Connect the direct wave detector and power meter to

the ANT terminal, apply the prescribed A.G. input from
the MIC input terminal, and transmit.
Turn the

[ENCODER]

knob to adjust the direct wave

detector reading to the prescribed value.

6. When the prescried value is reached, stop transmission

and press the

[SET]

key to set the adjustment value.

Note:

To end adjustment mode, switch off the power.
