CW Break-in adjust:
(1) Set the mode switch in the CW position and the vr will automatically switch the IC-201
to transmit.
(2) As with the VOX circuit, the return to receive time is adjusted by the Break-in time con-
stant control. Turning counter clockwise shortens this time.
Remember to turnoff the VOX control switch when not using VOX.
5.5 FOR REPEATER USE
You can transmit at 600KHz below any receive frequency for repeater use by placing the
Course Switch in the Duplx position. You may transmit at any frequency difference
up to at least 600KHz above or below the receive frequency, by installing a crystal in the
spare crystal socket in the pre-mix module in accordance with the formula shown as
follows. |

The necessity of completely realigning ie unit is unlikely. The most common cause of break-
down is component failure.
It is felt that the average owner would not have the necessary
equipment and facilities to accomplish realignment in any case, if it did become necessary.
Great care and precision are employed in its manufacture, and service is provided to ensure it
meets specifications. Adjustments not outlined here in, should not be undertaken by the owner.
This equipment has been carefully aligned with very expensive and accurate equipment, including
a Spectrum Analizer to reduce Spurious Radiation. |
DO NOT adjust, replace parts, or perform any type of maintenance unless you are fully qualified
to do so.
