NOTE: If the CW side tone level limit or beep level limit is in use, the CW side tone or beep tone decreases
from the fixed level when the [AF] control is rotated above a specified level. (pp. 12-5, 12-6)

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.
