Many aspects of this transceiver's configuration may be customized using the convenient
"Menu" system, which allow you to configure many "set and forget" settings just the way
you want to. A full discussion of the Menu system beings on page 58; for now, here is a
brief discussion on how to change Menu settings:

817ND has been exported. In the U.S. version,
the default function of this control is "RF Gain."

If your transceiver is configured for "RF Gain" use, rotating this control fully clockwise in
the SSB/CW/Digital modes will provide best sensitivity. To reduce the receiver's RF Gain
somewhat, rotate this control counter-clockwise slightly. You will observe an increasing

FM and Packet modes, this control will automatically be set to an "Auto-Squelch" mode,
wherein the FM/Packet squelch threshold is pre-set at the factory; the
acts as an "RF Gain" control, however, and it normally should be set fully clockwise.
If this control is configured for "SQL" operation, the FT-817ND's RF Gain will be set for
maximum sensitivity in all modes, and the

ceiver quiet when no signal is received. The LED just above the Main Dial will glow Green
when the squelch is opened by an incoming signal or noise.
Battery consumption is significantly reduced if the receiver is squelched, as the
audio amplifier stage is shut off when the receiver is muted.
