Sigtronics transcom ii, Specialists in “sound” management, A portable battery powered intercom
BATTERY OR AIRCRAFT POWER: The Transcom II is powered
by an internal 9V battery enabling approximately 40 hours of
operation in airplanes lacking a cigarette lighter socket. An
auxiliary 4 foot power cord with LED Power Indicator is supplied
for use in airplanes which have a socket. The LED indicator will be
on if power is available, it will be off if no power or reversed socket
wiring. Note: The LED shows power available, not intercom On
or Off. When using the power cord the battery is bypassed,
thus preserving the life of the battery. It is not necessary for
the battery to be operative in order to use the auxiliary power
cord. The battery powered feature is especially convenient for
students and instructors who move from plane to plane.
VOICE ACTIVATED: The voice activation feature allows “hands-
free” communication between pilot and co-pilot. Start speaking
and the intercom instantly turns on (no clipping) to relay your
message clearly to the other headsets; stop talking and it turns
off to reduce background noise.
TRANSMIT: Use your portable push-to-talk switch for transmitting
to air traffic control. Transmitting can be accomplished from
two positions (pilot and co-pilot). The intercom function is
automatically disabled during transmitting, so that only the
voice of the person transmitting goes over the air. However, the
transmitting person’s voice is heard at all headset positions via
the side-tone output. This feature is especially valuable to the
instructor and the student who wish to monitor each other’s
transmissions.
FAIL SAFE RADIO COMMUNICATIONS: Even with the intercom
“OFF”, the pilot can hear all radio communications and can
transmit through the aircraft radio using the headset boom
mic. The headset mic is routed directly to the radio via the “ON-
OFF” switch. The “fail safe” feature also works should the battery
go dead in mid-flight, thus providing the most fail-safe unit on
the market.
AUXILIARY AUDIO OUTPUT: Record ATC clearances or flight
instructor’s lessons on your cassette player.
AUXILIARY AUDIO INPUT: Plug in your portable music source
and enjoy music or instructional recordings!
WARRANTY: The Transcom II is constructed of high quality
components, carries a five year parts and labor warranty, and is
manufactured in the U.S.A.
