Section I - General Information
1.1 SCOPE
This section provides detailed operating instructions for the UPS
Aviation Technologies SL10, SL10S, SL10M, SL10M-S, SL10C,
SL10S-C, SL10M-C, and SL10M-S-C Audio Selector Panel/Intercom
Systems. Please read it carefully before using the equipment so that you
can take full advantage of its capabilities.
This section is divided into four sections covering the basic operating
areas of the SL10 systems. They are: Audio Selector, Transceiver
Selection, Intercom, and Marker Beacon Receiver (SL10M and SL10MS
only).
1.2 Audio Selector (All models)
Through the use of two
momentary and seven latched,
push-button, back-lit switches, it is
possible to select any or all
receiver audio. C1 and C2 are
momentary switches.
When selected, an internal
backlight will illuminate
indicating which audio source is
selected. Because the rotary switch
controls what transceiver is being
heard by the pilot and copilot (the crew), "Cl" (Com 1) and "C2" (Com 2)
push-buttons are of the momentary type and do not remain in when
selected. This is also part of the "auto function." You will always hear the
audio from the transceiver that is selected by the rotary mic selector
switch.
The users can identify which receivers are selected by noting which
push-button switches are illuminated. Push buttons labeled Nl (Nav 1),
N2 (Nav 2), D (DME), M (Marker), A (ADF), AX (auxiliary), and S
(Speaker) are "latched" type switches. When one of these buttons is
pressed, it will stay in the "in" position. Press the switch again and it be
in the "out" position and remove that receiver from the audio. While
selected, the switch will also be annunciated by an internal lamp.
NOTE: In Split Mode, no pushbuttons will be active. The only audio
selected is the com 1 and 2, as indicated by their respective lamps.
