4 SL15-Series Pilot Guide
When the mic selector switch is in the Com 1 position, both pilot and copilot
will be connected to the Com l transceiver. Only the person who presses their
Push To Talk (PTT), will be heard over the
aircraft radio. Turning the rotary switch to the
C
OM 2 position will place pilot and copilot on
Com 2.
The SL15 gives priority to the pilot’s PTT. If
the copilot it transmitting, and the pilot presses
his PTT, the pilot’s microphone will be heard
over the selected com transmitter.
Turning the mic selector fully counterclockwise places the pilot and copilot on
Com 3. Com 3 receive audio is automatically placed in the headset (and
speaker if selected). Com 1 and/or Com 2 receiver audio can be selected to
monitor those transceivers.
The SL15-Series has an automatic selector mode. Audio from the selected
transceiver is automatically heard in the headsets and speaker. You can check
this function by switching from C
OM 1 to COM 2 and watch the selected audio
light on the selector change from COM 1 to COM 2. This ensures the pilot will
always hear the audio from the transceiver he is transmitting on.
When switching the mic selector rotary switch from C
OM 1 to COM 2, while
C
OM 2 audio had been selected, Com 1 audio will continue to be heard. This
eliminates the pilot having to switch Com 1 audio back on, if desired.
When switching from C
OM 1 to COM 2 while Com 2 has NOT been selected,
Com 1 audio will be switched off. In essence, switching the mic selector will
not effect the selection of Com audio.
The “TEL” position, fully CW on the mic selector switch, is the pilot’s “hook”
switch, when the system is interfaced to an appropriate approved wireless tele-
communication system, such as the AirCell system. Placing the mic selector in
TEL placed the pilot microphone and headphones on the cellphone. The pilot
PTT will switch the pilot mic to the COM 1, and allow continued aircraft com-
munications as well.
The copilot will also be able to transmit on COM 1 with his PTT as well.
NOTE
Placing the mic selector switch in the TEL position will disable pilot and copi-
lot intercom, as the intercom circuit is transferred to the telephone use. In
crew or ISO mode, placing the switch in TEL mode removes the passengers
access to the telephone.
3.1 Swap Mode (Switch from Com 1 to Com 2 remotely)
With a yoke mounted, momentary switch, the pilot can change from the current
Com transceiver to the other by depressing this switch. When "Swap Mode" is
active, an annunciator in the lower right corner of the unit will illuminate, indi-
