・How to use the SDC1

1, Connect it as shown in below. Plug the cigar plug

into a cigar socket.

2, To turn the power switch ON, LED lamp turns on

and the current operation situation is shown on
the display panel.

3, Turn the frequency change dial and set the

operation frequency.

4, When pushing the GO button, the frequency and

“GO HOM POSITION” will be shown in the
display panel and the coil will be moved to the
lowest position. After that, the coil will be moved
to the selected frequency. The frequency and
position count number will be shown at that time.

5, When the coil goes to the selected frequency, the

coil will be stopped automatically. After stopping
the coil, please transmit at less than the output
10W. Adjust the SWR by UP/DOWN buttons.
(Since the antenna’s conditions will be changed
depending on the surrounding condition, weather
and installation place. Please make sure to
check SWR.

6, To keep pushing the UP button, the coil will be

moved to the highest position and be stopped
moving. Since the internal motor will keep truing,
stop pushing the UP button at the earliest. After
that, to push the RESET button and push the GO
button, the coil will be moved to the selected
frequency.

7, If you want to stop the coil during operation, push

the RESET button. The coil will be stopped at the
position.

8, When you want to re-start the UP/DOWN

movement, go back to 3 or push UP/DOWN
buttons. The coil will be moved.

9, When operating 50MHz band, use the optional

element “OPE750”.

●The SDC1 is not the water proof structure. Do

not get water to the product.

●Since the inside of the SDC1 is a complicated

electronic circuit, don’t use it where is a strong
magnetic field or high temperature and
humidity.

●Since the dashboard of the car becomes high

temperature, don’t install the product at the
dashboard.
