The indicated SSG output level are for maximum output.

Whenever there is no modulation desingnation,

standard modulation (MOD : 1kHz, DEV : 3kHz (Wide),

DEV : 1.5kHz (Narrow)) is indicated.

When adjusting the PLL lock voltage, you must set If you transmit without connecting a 50Ω terminator on the

the TX POWER value to 0. antenna connector, the FET final transistor may be damaged.
