Getting Started Getting Started Combining powerful channel communications transceiver with 200 channel VOR, Localizer and Glideslope receivers, the SL30 provides a full-functioned navigation and communications solution in a small footprint at a very affordable price. Besides traditional Nav/Comm features, SL30 also incorporates workload-reducing...
Getting Started Display The SL30 Nav/Comm uses a single line by 32-character 5x7 dot matrix alphanumeric display. 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.

Getting Started Standby frequency. See the Advanced Operation section for more about monitoring frequencies. Press to select the Nav radio mode. The annunciator above the button will light when you are in Nav mode. Press a second time to monitor the Standby frequency.
Getting Started annunciator will light above the button when this function is active. Press to save selected values, to confirm a prompt, or to save the Standby frequency. Operation Summary Power On Turn the SL30 on. Either turn the Power/Volume knob clockwise to turn the power on or, if installed, turn on the master switch that powers the radios.
Getting Started Selecting a Comm Frequency New frequencies are first selected as a Standby frequency and then toggled to the Active side when desired. While LARGE viewing the Standby frequency display, use the SMALL knobs on the right side of the SL30 to select the desired frequency.
Getting Started System Mode In the System mode you can view software versions, setup the Nav and Comm functions, and record VOR test information. See the Advanced Operations section for more details. OBS Mode Press the button. If the annunciator above the button LARGE SMALL lights, then you may use the...
Advanced Operation Advanced Operation Comm Radio Mode Monitoring the Standby Comm channel The Frequency Monitoring function allows you to monitor the Standby frequency for activity, while listening to the Active frequency. Press the key in the Comm function to listen to the standby frequency.
Advanced Operation 1. While in Comm mode, press . The right side of the display will show “store as” with a flashing cursor at the first character of the name. 119.10 s124.55 store as _ SMALL 2. Turn the knob to choose the desired character. LARGE 3.
Advanced Operation LARGE SMALL 4. Use the knobs to enter the previously used name and frequency type. 5. Press . The previously used name and frequency are now replaced with your new entry. Recalling Comm Channels There are several lists of channels that you can recall from memory, they are: remote channels, the ten most recently used channels, user-stored channels, weather channels, and the emergency channel.
Page 16
Advanced Operation Automatic Comm Channel List (Autolist) The last ten used active frequencies are available separately for Nav and Comm channels (ten for Nav and ten for Comm). The channels are stored in chronological order beginning with the most recent used. Duplicates are not saved again, but they are moved to the front of the list.
Advanced Operation Weather Channels The standard weather channels are stored in the memory of the SL30. You cannot transmit on a weather channel frequency. Weather channels are not available in all locations. Weather Frequencies 162.400 MHz 162.425 MHz 162.450 MHz 162.475 MHz 162.500 MHz 162.525 MHz...
Advanced Operation Stuck Mic The SL30 helps protect you from a situation where the microphone may get stuck in the ON or Transmit position. If the microphone is keyed for longer than 35 seconds, the SL30 will return to the receive mode on the selected frequency.
Advanced Operation Nav Radio Mode Monitoring the Standby Nav channel The Nav radio provides a monitor function for VORs as the standby channel similar to the Comm radio. The monitor function is activated or deactivated by pressing button while in the Nav function. The From radial for the standby channel is shown in parentheses when the VOR monitor mode is activated.

Advanced Operation Navigating along a Back Course approach 1. Press to select the Nav receiver. 2. Set the Localizer frequency of your approach as the Active channel. 3. Press . The display will prompt you to enable the back course. Press to enable the back course.
Page 21
Advanced Operation Navigating to a MAHP 1. Press to select the Nav receiver. 2. Set the VOR frequency for the radial you are following to the MAHP as the Active channel. 3. Set the Standby channel to the appropriate VOR and note where a radial crosses the MAHP for your runway.
Advanced Operation Listening to the Audio channel The audio for the active Nav channel is toggled between modes using the button. The annunciator above the button will light while Nav audio is activated, and the detected audio signal will be sent to the Nav audio output circuit.
Advanced Operation Saving a Nav channel You can save the frequency in the Standby position and give it a name of up to four characters. Additional information can be saved along with the name, if the selection is a Localizer or ILS. ILS selections may include the runway number (01-36) and designation (L, R, or C).
Advanced Operation Recalling a Nav channel There are several lists of channels that you can recall from memory in Nav mode. Remote Localizer, remote VORs, the ten most recently used channels in Nav mode, and the user-stored channels. 1. In Nav mode, press LARGE 2.
Page 25
Advanced Operation Remote Localizer List If Localizer channels have been sent by an external device, then this list will be the first displayed for convenience while preparing for a landing. The list shows the airport identifier on the left, a runway identifier for the station in the center, and the channel frequency on the right.
Advanced Operation DST Data Display When the SL30 has received data from an external device, such as a DME sensor, through the serial port, DST data is added to the Nav recall list. If you aren’t connected to an external sensor, you will not see this display. If the display of Distance-Speed-Time (DST) data is not activated, you will be prompted to show the data when you view the DST selection in the channel recall lists.
Advanced Operation OBS Mode OBS Operation OBS mode enables the VOR CDI which is displayed on the right side. The OBS course setting is shown in the center of the display. The button is used to select this mode. If OBS mode is allowed in the unit’s installed configuration, the annunciator over the button will light.
Page 28
Advanced Operation The CDI display is selected by pressing the button. The CDI display is not available if the SL30 is set to use an external indicator head that does not provide a resolver input. The graphic CDI shows an airplane icon at the center that points up in the To condition or down for From.
Page 29
Advanced Operation the additional information only switches sides after the CDI deflection has exceeded two degrees on the side that is currently used. Localizer A localizer (ILS) frequency is distinguished from the VOR OBS display by the label, “loc,” to the left of the CDI rather than the OBS course.
Advanced Operation 3) The SL30’s internal CDI will show “BC” and the external CDI annunciator will show “BC.” 111.10 s116.00 loc bc +}} 4) Make sure you are flying a Back Course approach, because the CDI is now reversed so you can still “chase”...

Advanced Operation System Info System Info provides information about the Software versions and the Display Intensity. LARGE 1. Press and turn the knob if necessary to the System Info page. Press LARGE 2. Turn the knob to view the selections. Software Version The Software version is available for reference when you contact Technical Support.
Advanced Operation Nav Options Nav Audio Level This setting is for the SL30’s output to its external audio panel. The factory default value is “Variable”, which slaves it to the volume knob. The range of values it can be set to are 1 to 100. Nav/Comm Mixing Level The Nav audio output may be mixed with the com audio output for installations without an audio panel.
Advanced Operation Comm Options The Comm Options selection allows you to set up options available for Comm radio operation. LARGE 1. In the System mode rotate the knob to display the Com Options page. Press LARGE 2. Rotate the knob to view the Com Options RF Signal Level The RF Level function shows the relative signal strength of the active frequency.
Advanced Operation Intercom Level This function adjusts the Intercom Audio Level. Turn the SMALL knob to change the value. The range is from 1 to 100. Setting the value to “variable” slaves the intercom level to the volume control knob. Sidetone Level This function displays and adjusts the sidetone audio level that is heard when the transmitter is keyed.
