The Quick Reference Guide is part #561-0262-xx. About This Manual Please take a few moments to review the various sections in this manual. Even if you are an experienced user of Nav/Coms, be sure to read our Getting Started section.
Getting Started Combining a powerful 760 channel VHF 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 tradi- tional Nav/Com features, the SL30 also incorporates workload-reducing functions such as automatic decoding of the Morse code station identiﬁer for VOR/LOC, most-used frequency storage in memory, built-in course deviation indicator, and more.
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.
Flip/Flop Press the FLIP/FLOP button to switch between the active (left-most) and standby (right- most) frequency. Switching between Com frequencies is disabled while you are transmit- ting. Press COM to select the Com radio mode. The annunciator will light above the button when you are in Com mode.
Getting Started Press T/F to toggle between the bearing TO or radial FROM the active VOR. The T/F but- ton does not operate for Localizer frequencies. Press ID to select the Nav audio and toggle between VOICE or IDENT. Pressing ID will cancel the VOR monitor function.
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. The SL30 will go through a short initialization routine and then brieﬂy display the last VOR check date.

Advanced Operation Com Mode 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. A “Stuck Mic”...
Nav Radio Mode Monitoring the Standby Nav channel The Nav radio provides a monitor function for VORs as the standby channel similar to the Com radio. The monitor function is activated or deactivated by pressing the NAV 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 Nav Mode Navigating along a Back Course approach 1. Press NAV to select the Nav receiver. 2. Set the Localizer frequency of your approach as the Active channel. 3. Press SEL. The display will prompt you to enable the back course. Press ENT to enable the back course. Press SEL and ENT again to disable the back course when it’s appropriate.
Navigating to a MAHP 1. Press NAV 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 Nav Mode Listening to the Audio channel The audio for the active Nav channel is toggled between modes using the ID 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.
Saving a Nav channel You can save the frequency in the Standby position and give it a name of up to four char- acters. 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). Up to 250 Com and Nav frequencies may be saved.
Advanced Operation Nav Mode 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.
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 Nav Mode 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.
