2.1 UNPACKING
Remove the TS-830S from its shipping container and
packing material and examine it for visible damage. If the
equipment has been damaged in shipment, notify the
transportation company immediately. Save the boxes and
packing material for future shipping or moving.
The following accessories should be included with the
tranceiver.

2.2 OPERATING LOCATION
As with any solid state electronic equipment, the TS-830S
should be kept 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
to any object. This space allows an adequate air flow from
the ventilating fan to keep the transceiver cool.
SECTION 2. INSTALLATION
CAUTION:
Do not operate the radio in an RF Field greater than 6V RF.
Receiver damage may occur.
2.3 CABLING (See Figure 2-1.)
@ GROUND
To prevent electric shock, and reduce the possibility of TVI
and BCI, connect the transceiver to a good earth ground,
through as short and heavy a lead as possible. Use ground
rods or metal cold water feedline.
NOTE:
A ground connection greater than 1/4 away from the
transceiver may be a good DC ground, but NOT an RF
Ground.
@ ANTENNA
Connect through a 50 ohm antenna feedline to the coaxial
connector on the rear panel.
@ KEY
If CW operation is desired, connect a key to the KEY jack.
Use shielded line or coaxial cable.

@ POWER CONNECTIONS
Make sure the POWER switch on the front panel is turned
off, the stand-by switch is in the REC position, and the line
voltage is correct. Then connect the power cord to the line
source.
= AC POWER
For fixed station operation, the TS-830S is supplied to
operate from a 120V AC, 50/60 Hz power source capable of
supplying 280 watts or more.
2.4 MICROPHONE
Attach the microphone connector to a suitable microphone,
as shown in Figure 2-1. Be sure the microphone PTT switch
is separate from the microphone circuit, as shown in Figure
2-1A.
It should be noted that a microphone with a 3P plug using a
common ground terminal should not be used.
The microphone input is designed for 500~50 kQ
microphones. The choice of microphone is important for
good speech quality, and should be given serious considera-
tion. The crystal lattice filter in the transceiver provides all
the restriction necessary on audio response, and further
restriction in the microphone is not required. It is more im-
portant to have a microphone with a smooth, flat response
throughout the speech range.
Follow the microphone manufacturer's instructions for con-
necting the microphone cable to the plug. With many
microphones, the push-to-talk button must be pressed to
make microphone audio available. For VOX operation, this
unwanted feature may be eliminated, if desired, by opening
the microphone case and permanently connecting the
contacts which control the microphone audio.
Standard microphone sensitivity is within the range of —50
dB to —60 GB. If a microphone having a higher sensitivity
is used, the ALC and compressor circuits will not function
properly. In this case, insert in the mike line an attenuator as
shown in Fig. 2-1C. A typical MIC gain control setting is 12
o'clock. If you must run this control at 9 o'clock or less, use
an attenuator.
2.5 KEY
If CW operation is desired, connect a key to the KEY jack.
Use shielded cable, and a standard (mono or 2P) phone plug.
