To access this function, a switch is installed to connect the top connector, pin 18, to ground. This places the pilot microphone on the speaker output (Pin W) when the PTT is pushed. See Section 2. 5 We recommend that the switch transfer the audio from the cockpit speaker to a cabin speaker for public address. This will prevent feedback. 4. 2 Key "Click" The SL15 is equipped with a "click" function that provides an aural feedback to the user in addition to the tactile button push. This sound can be enabled or disabled by simultaneously holding the COM 1 and COM 2 buttons in for at least 5 seconds. Any person hearing the radios will also hear the key click. Allow at least 20 seconds between turning the key click on and off. A three-position switch is used to set the receiver sensitivity and to test the indicator lamps. Then select the "LO" sensitivity to give you a more accurate location of the Outer Marker. The momentary down switch position is marker test, labeled "T/M" and illuminates all three lamps simultaneously to assure the lamps (internal and external) are in working order. In units with serial numbers above "F" series in the first set of numbers, a marker mute function was added. Pressing the marker mode select down (to "T/M") will cause the marker audio to mute for that beacon. The next beacon received will re-activate the audio. 5 Split Mode Turning the rotary switch to COM 1/COM 2 places the SL15 into "Split Mode. " This places the pilot on Com 1 and the copilot on Com 2. An example of this useful feature is when the pilot may want to talk to Air Traffic Control, while the copilot may be speaking to Flight Watch. Although this mode has limitations (see below) we believe you will find this to be a useful feature. 9 Internal Recorder System (Optional) Switching to Com 2/Com l will reverse the "Split Mode" radio selection. NOTE The Intercom Recording System (referred to here as the IRS) is a digital recording system allowing automatic storage and playback of aircraft radio traffic. Operating as a continuous loop recorder, (first message received will be the last heard), the recorder has one minute of recording time or up to 16 messages. With its own built in VOX circuit, there are no buttons to press to start recording. The system automatically begins to record the instant the radio becomes active. Through three individual signal processors, the ambient noise appearing in all six microphones is constantly being sampled. [. . . ] Then, the pilot and copilot intercom is controlled with the ICS button. Pilot Hears Co-Pilot Hears Passenger Hears Telephone Comments This mode allows the pilot to communicate without the others bothered by the conversations. Copilots and passengers can continue to communicate and listen to music. All hear telephone audio if off hook. ISO: (Up Position): The pilot is isolated from the intercom and is connected only to the aircraft radio system. He will hear the aircraft radio reception (and sidetone during radio transmissions).
