SQL open SQL closed : Less than 0.3 V/5 mA : More than 6.0 V/100 µA *1 W hen 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. [Example] ACC socket eHSEND or uVSEND i13.8 V Switching diode Relay To a non-Icom linear amplifier *2 V SEND is used for the 144 MHz, 430 MHz, and 1200 MHz bands, and HSEND is used for the HF/50 MHz bands by default. You can change this setting in "VSEND Select" of the Set mode. (p. 166) *3 The pin 12 (AF) and pin 13 (SQLS) output capabilities are for the MAIN Band's AF and squelch by default. You can change this setting in "ACC AF/SQL Select" of the Set mode. (p. 166) 13
