1.0 Description

The ATD-300 Traffic-Watch is a passive receiver capable of detecting transponder
replies from nearby aircraft and displaying their range and altitude on an 8-character dot
matrix yellow LED display. It also provides distinctive voice warnings in relation to traffic
proximity. The ATD-300 has a detection range of 5 nautical miles. The system consists
of a receiver/indicator unit, antenna, power cord and headphone cable. The receiver is
housed in a small aluminum box (2.75 x 0.75 x 5.0) for easy location in the cockpit.

The ATD-300 provides distinctive voice warnings for traffic at different ranges. When set
in the FAR mode and traffic is within 3nm and +1,000ft of vertical separation "Traffic"
will be annunciated. As the traffic gets closer to about 1nm and within +1000ft of vertical
separation the message will change to "Traffic Nearby". When set in the NEAR mode
only traffic within 1nm and +500ft of vertical separation will be annunciated by "Traffic
Nearby". When set to MUTE there is no warning messages for any traffic, however
traffic range and MSL altitude will still be indicated. When there is no traffic activity the
ATD-300 will automatically indicate the host transponder MSL pressure altitude. A
screwdriver adjustable volume control is located on the bottom side of the unit. Audio
output to a speaker (8 ohms) or headphones (300 ohms) is provided on the rear of the
unit.

The ATD-300 features a built-in voltage-warning indicator that lets you know if the
aircraft supply voltage is out of range. This functions works on the background all the
time and is activate after engine start. If an out of range condition exist the ATD-300
annunciates it by voice and by text.

Note: The ATD-300 will not detect aircraft that do not have an operating
transponder. Mode A/C transponders outside a surveillance environment will not
produce replies so they will not be detected by the ATD-300. The ATD-300 is not a
substitute for continuous traffic surveillance, NOT ALL AIRCRAFT ARE
TRANSPONDER EQUIPPED.

2.0 Setting up

The ATD-300 Plug & Fly feature allows the owner to operate the unit right away without
the need to have it permanently installed in the aircraft. See fig. 1 for set-up

1) Connect the provided rubber antenna to the rear BNC connector on the unit. Align
the antenna vertically.

2) Find a suitable space on top of the glare shield where the ATD-300 is accessible and
not blocking the pilot's view and the antenna is not in contact with the windshield or
airframe structure.

3) Clean well this glare shield location and stick one of the Velcro strips provided. Stick
the other strip to the bottom side of the unit. Make sure the strip does not block the
VOL adjustment hole.

Note: The ATD-300 can also be located on the overhead panel with the antenna
pointing down. However, depending on the surface the Velcro strips may not provide
long time support.

4) Plug the cigarette lighter power cord to the rear center connector of the unit. Plug the
other end to the cigarette lighter jack in the aircraft.

5) Plug the headphone cable mini-plug to the rear connector on the unit. Plug the other
end 1/4" plug to the aircraft headphone jack. Connect the pilot's headphone to the
pigtail phone jack on the cable.

Note: If the aircraft is equipped with an intercom system or BOSE ANR headsets
connect the 1/4 plug to the emergency headset jack for better results. The pilot's
headphones can be connected to their respective phone jacks in the aircraft.

6) Turn on the A/C master switch. Set the ATD-300 left switch to NEAR. Turn the unit
on (right switch up). After two seconds you should hear "Traffic Watch On". Adjust the
volume control on the bottom side if it is to high or to low, use a jeweler's screwdriver.
Clockwise rotation increases the volume. Repeat the above until desired audio level
is achieved

7) Affix the ATD-300 to the glare shield. Route the power and headphone cable so they
do not interfere with the operation of the aircraft.

Note: During the summer, the ATD-300 may get too hot to the touch if exposed to the
sunlight when the aircraft is parked outside. It is recommended that it be covered
with a chart or equivalent when parked outside. If the unit gets too, hot it may not
work properly until it cools down.
