NOTE: If the CW sidetone level limit or beep level limit is in use, the CW sidetone or beep tone decreases from
the fixed level when the [AF] control is rotated above a specified level. (p. 130)

When the SEND terminal controls the inductive load
*
(such as a relay), a counter-electromotive force can
cause the transceiver's malfunction or damage. To
prevent this, we recommend adding a switching
diode, such as an "1SS133," on the load side of the
circuit to the counter-electromotive force absorption.
When the diode is added, a switching delay of the
relay may occur. Be sure to check its switching
action before operation.
