2. INSTALLATION
2-1. PRECAUTION
1. Avoid direct sunlight, and select a dry, well venti-
lated location.
2. Since the heat sink is on the rear panel, avoid plac-
ing the equipment with the bottom and rear sides
close to a wall or desk.
3. When installing the equipment in an automobile, en-
sure adequate ventilation. Install the equipment in
2-2. FIXED STATION

Interconnection
The TS-440S/44X
requires more than 18A at 13.8
VDC when transmitting at full power. Use the PS-50
or PS-430 power supply for fixed stations.

Grounding
Caution:
Never use a gas pipe or electrical conduit pipe.
Notes:
1. A ground connection that is a 1/4 wavelength or
its multiple may provide a good DC ground, but it
will not provide a good RF ground.
2. A city water pipe cannot be used as a good earth
in some cases.
a location where the rear does not make direct con-
tact with the seat, and is not directly exposed to
vibration.
4. Avoid installing the equipment in front of the car
heater air outlet.
5. The standard operating voltage of the equipment
is 13.8 V. Do not operate below 12 V or over 16 V.
The transceiver can be elevated for operating con-
venience.
Caution:
Do not use the bail to carry the transceiver.
TS-440S/44xX
Making
a good
earth
connection
is important
for
preventing dangers such as electric shock and for emit-
ting a high quality signal with minimum spurious radi-
ation. Bury
a commercially available ground
rod or
copper plate under the ground and connect it to the
GND terminal of the TS-440S/44X. A thick wire, cut
as short as possible, should be used for the connection.
To make a good earth connection, connect the GND
terminal to a metal water pipe grounded.
