Sigtronics RES-2 - Manual (Page 2)

CHASSIS INSTALLATION
Select a mounting location which will not cause interference with
flight controls. Four 6/32” screws with self locking nuts have been pro-
vided for mounting the chassis to the aircraft.
1. Remove the unit from the case.
2. After selecting a suitable mounting location in the aircraft, drill air-
craft and switcher case with the same hole pattern. Use a No. 27 drill
(Clearance drill for 6/32”).
3. Secure case to the aircraft with the screw heads inside switcher case
for circuit board clearance.
4. Replace the unit in the case and secure.
WIRING INSTRUCTIONS
Four feet of cable has been provided to connect the unit to the aircraft
and entertainment system.
Figure 1 illustrates the connections to be made.
Table 2 lists the connector plugs and pin numbers, the color, function
and destination of each wire connected to those pins. Connections
should be made as shown in Figure 1 and as indicated in Table 2.
Sigtronics should be contacted if other means of connecting the unit
are contemplated.
OPERATING INSTRUCTIONS
Step 1. Turn aircraft radio “ON” and adjust both squelch (if manual)
and volume to suitable listening level.
Step 2. Turn Audio Switcher and entertainment system “ON” and
adjust entertainment to suitable listening level.
Step 3. Select Pilot or All position to suit switching mode desired.
Note: The Switcher controls can be changed from one mode to
another at any time. (See Mode Selection Table 1)
TRANSMIT: Transmitting is accomplished in the conventional manner,
by using your headset or hand-held microphone. Messages are received
via the headphones being worn. If the pilot has a headset with a boom
microphone and uses a push-to-talk switch, then the headset micro-
phone plug should be connected to the aircraft microphone jack and
the headphone should be connected to the switcher headphone jack.
