Getting Started
Display
The SL30 Nav/Com uses a single line by 32-character 5x7 dot matrix alphanumeric dis-
play. A photocell is located in the top left corner of the front panel display. The photocell
automatically controls the light intensity of the display LEDs from low brightness at night to
high brightness during daylight operation. The lens is polarized to reduce reflections. Using
polarized sunglasses may make it difficult to view the display.
TX
A transmit (TX) indicator located above the FLIP/FLOP button lights when the Com
radio is transmitting.
Controls
Power On/Off - Volume - Squelch
The knob on the left side of the SL30 controls power on/off, volume, and squelch test.
Rotate the knob clockwise (CW) past the detent to turn the power on. Continuing to rotate
the knob to the right increases speaker and headphone amplifier volume level. Rotate the
knob to the left to reduce the volume level. Pull the knob out to disable automatic squelch.
The SL30 may be configured to have the volume knob control Nav and intercom volume, as
well as Com volume.
Large/Small knobs
The dual concentric knobs on the right side of the SL30 are used to select frequencies, to
view the features available within a function, or make changes. Details are provided in the
appropriate sections.
