Local Mode Button
The radio features a Local Mode button that decreases radio
sensitivity when operating inside populated areas.
When the Local Mode button is On, the power of an
inbound receive (Rx) signal is reduced without distorting
the waveform. Reducing an inbound signal power
prevents “noise interference” from random RF Noise in
populated marinas, cities and commercial areas. When
the Local Mode button is On, the “Local On” icon
displays.
When the Local Mode button is Off, the radio receives a
full signal with an extended operational range.
Channel Preset (Function) Buttons
Use the Channel Preset buttons for direct access to favorite
channels in the Standby mode and as selection keys in the
Setup mode.
When a Channel Preset button is pressed and released,
the radio goes directly to the assigned preset channel. If
no preset channels are assigned, three (3) error tones
sound. After the button is released, the radio returns to
the Standby mode.
When a Channel Preset button is pressed and held for
more than two (2) seconds, the working channel will be
assigned to the button.
