2-2. OPERATING LOCATION
As with any solid-state electronic equipment, the place
of use must be discriminated with the TS-700A, in order to
avoid subjecting to extremes of ambient conditions.
A well-ventilated, dry place, where the transceiver will
not be exposed to direct sunlight, should be selected. The
TS-700A has a heat sink in its rear panel; be sure to install
the transceiver so that there is a proper clearance at the rear
and bottom. For better heat dissipation, keep it away from a
wall. This precaution also applies when the transceiver is
operated on the companion's seat in a car.
When you wish to use the transceiver in a car, you may
put it on the seat but sure to secure some heat dissipating
clearance under and behind it and to make proper provisions
for protecting it against shocks.
2-3. POWER SUPPLY CONNECTION
The TS-700A is designed to operated on AC
120/220 V or DC 13.8 V. Switching between AC and DC is
accomplished by replacing the power cord. The DC power
cord is color coded (red for''+" and black for '—"'). When
connecting power cord, be sure to observe the following
points:
1. Turn off the power switch and set the standby switch to
REC position.
2. When replacing power cord, disconnect it from the AC
socket (or battery). Care should be used to prevent
electrical shocks when connecting the AC power cord.
Each power cord is equipped with a 4-P plug complete with
a stopper. When inserting the plug to the transceiver, be
sure to press down the stopper with your finger and engage
it into the latch on the transceiver side.
To pull the cord off the transceiver, push down the
stopper to disengage it from the latch and then give a pull to
the cord end. (See Fig. 1)

2-4. ANTENNA CONNECTION
To ensure maximum enjoyment of QSO, the use of a
good antenna is important. A standard ground-plane anten-
na or a Yagi antenna will give you best results. This antenna
should be set up about 10 to 20 meters high and a coaxial
cable connected to the antenna terminal of your transceiver.
When communicating with a far-away station or with a
particular station, the use of a high gain, directional Yagi
antenna is recommended. For local communications, use a
non-directional antenna.
2-5. MICROPHONE
The microphone supplied with this transceiver is a
500-ohm impedance one designed specially for radio equip-
ment of this class. Any other microphone may be used
provided that its type and characteristic are suited to the
transceiver. The optimum impedance of a microphone is
anywhere between 500 and 600 ohms. For connection of
microphone, refer to Fig. 2 and Fig. 3.
2-6. SENDING KEY
For CW operation, connect a sending key device to the
KEY jack at the rear of the transceiver. CW mode is
defeated by manipulating the mode switch, allowing you to
operate in SSB, AM or FM mode.
2-7. EXTERNAL SPEAKER
A small sized speaker is built in TS-700A. If you wish
to use an external speaker, connect it to the EXT SP jack at
the rear of the transceiver by using the supplied speaker
plug.
It is recommended that a speaker rated at 8 ohms of
impedance and whose low and high ranges are sharply cut
off be used for this purpose. Plugging in an external speaker
cord will automatically cut the built-in speaker out of service.
When connecting an external speaker, be careful not to
short the AF output and try to minimize the length of the
cord, which should preferably be of shielded type, so as to
prevent radio-frequency energy from reaching the speaker
through the ground.
