2-1. PRECAUTION

1.A void 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

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.

2-2. FIXED STATION

2-2-1. Interconnection

The TS-440S 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.

Note:

The PS-50 base station supply is needed for continu-

ous transmission operation.

		The transceiver can be elevated for operating con-
		venience.

2-2-2. 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.

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. 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 grounded metal water pipe.
