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 adjsutment 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. When the prescribed value is reached, stop
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’.
