Deviation : ±3.5 kHz
• Set the SSG as;
Frequency : 136.020 MHz
• Set the SSG as;
Frequency : 147.980 MHz
• Set the SSG as;
Frequency : 173.980 MHz
1) C o n n e c t a n S S G t o t h e a n t e n n a
connector and set it as;
Frequency : 145.020 MHz

†
Modulation : 1 kHz
Deviation : ±3.5 kHz
2) Once close the squelch by increasing [Sq]
value, then decrease the value to open the
squelch.
3) Push [S.MW] to store the value.
