UNPACKING
Remove the TS-900 and its power supply from their
ship-
ping boxes
and packing
material
and examine
them
for
visible damage.
If the equipment
has been
damaged
in
shipment, save the boxes and packing material and notify
the transportation company
immediately.
It is a good idea
to save the boxes and packing material in any case because
they are very useful for shipping or moving the equipment.
The
following
accessories
should
be included
with
the
transceiver:
1 Operating Manual
1 Alignment Tool
1
Microphone Plug
2
Plastic Extension Feet
The POWER
SUPPLY
cord and fuses are included with
the power supply.
2.2
OPERATING
LOCATION
As with any solid state electronic equipment
the TS-900
should
be kept free from extremes of heat and humidity.
Choose
an operating
location
that
is dry and
cool, and
avoid operating
the transceiver
in direct sunlight.
Also,
allow at least 3 inches clearance between the back of the
equipment
and any object.
This space allows an adequate
air flow from the ventilating fan to keep the TS-900 cool.

CABLING
(See Figure 2)
GROUND
Connect
a wire from a good earth ground to one of the
GROUND
studs on the back of the transceiver.
If a good
earth ground
is not available and the TS-900
is operated
from an approved three-wire electrical system in the United
States,
the third or neutral wire will normally
supply an
adequate ground.
ANTENNA
Connect
a 50 ohm
antenna
feedline
to the coaxial con-
nector on the rear panel.
If a different receiving antenna
is desired connect that
line to the REC ONLY
jack.
KEY
If CW operation is desired, connect a key to the KEY jack.

RTTY
If RTTY
operation
is desired, connect
the
RTTY
input
to this jack.
The TS-900
has a built-in frequency
shift,
factory adjusted for 850 Hz.
POWER
SUPPLY
Make
sure
the POWER
switch
on the front panel of the
TS-900 is turned off, the stand-by switch is put in the REC
position, and that the voltage switch on the back of the
PS-900 is switched to the correct line voltage (120 or 240).
Connect the POWER
SUPPLY
cord to the PS-900, the DS-
900, or an appropriate external power supply.
SPEAKER
Connect
the speaker
cord to the SPEAKER
jack on the
back of the TS-900 and to the SPEAKER jack on the back
of the PS-900 (or to an external 8 ohm speaker).
MICROPHONE
Attach the microphone connector to a suitable microphone.
Be sure that the PTT switch of the microphone
is separate
from the microphone circuit, as shown in Figure 3. Figure
4 shows how to install the microphone connector.
Finally connect the power supply to your power source.
Set the POWER switch to OFF, and the
stand-by switch to REC
before connecting
the AC plug to an outlet.
