SECTION 5. ADDITIONAL INFORMATION
5.1 GENERAL INFORMATION
Your TS-120S(V) has been factory aligned and tested to
specification before shipment. Under normal circumstances,
the transceiver will operate in accordance with these
Operating instructions.
If your transceiver fails to work, contact the authorized
dealer from which you purchased it for quick, reliable repair.
All adjustable trimmers and coils in your transceiver were
preset at the factory and should only be readjusted by a
qualified technician with proper test equipment.
Attempting service or alignment without factory authoriza-
tion can void the transceiver's warranty.
5.2 HOW THE TX FINAL TRANSISTORS ARE
PROTECTED
Final transistor protection is provided by sampling the
reflected power. As the reflected power is increased (higher
SWR) transmitter drive is reduced, thus decreasing input to
the final transistors. This in turn reduces collector loss,
protecting the final transistors.
5.3 ORDERING SPARE PARTS
When ordering replacement or spare parts for your equip-
ment, be sure to specify the following:
@ Model and serial number of your transceiver, Schematic
number of the part, Printed circuit board number on
which the part is located, Part number and name, if
known, and Quantity desired.
5.4 SERVICE
Should it ever become necessary to return the equipment for
repair, pack in its original box and packing, and include a full,
detailed description of the problems involved. Also include
your telephone number. You need not return accessory
items unless they are directly related to the service problem.
NOTES:
When claiming warranty service, please include a photocopy
of the bill of sale, or other proof of purchase showing the
date of sale.
poennnne etna
The following optional accessories are available for use with
the TS-120S(V).
= * Model PS-20 Regulated DC Power Supply
Perfectly matches the design and characteristics of the TS-
120V. Equipped with a protection circuit which guards
transceiver against damage due to shorts or overload.
= Model PS-30 Regulated DC Power Supply
The PS-30 is a regulated DC power supply with a large
capacity. The output is 13.8 VDC/20A (Intermittent). Since
terminals for 13.8 VDC/5A are also provided, in addition to
output power cables for use with the TS-120S, the PS-30
can be used as a power source for other mobile transceivers
(such as 2-meter rigs).
= Model AT-120 Antenna Tuner
The AT-120 is a compact antenna tuner designed for use
with the TS-120S(V) in either a mobile or fixed station. The
SWR meter is illuminated so that it can be used in the car
even at night. Also, it is equipped with a highly accurate
SWR detecting circuit for matching within the impedance
range between 20 and 300 ohms on five bands between 3.5
and 29.7 MHz.

SECTION 6. OPTIONAL ACC
ESSORIES
= Model VFO-120
The VFO-120 is an all solid-state VFO with high stability,
designed to match the TS-120S(V) in design and perfor-
mance. "Split frequency" operation is possible by using the
TS-120S(V) with the VFO-120. Also, the T-F switch makes
it possible to check the transmit frequency while in the
receiving mode.
= Model SP-120 External Speaker
The SP-120 is an external speaker designed exclusively for
use with the TS-120S(V). It matches the TS-120S(V) in
design and tone quality.
= MICROPHONE MC-30S, MC-35S
Dynamic microphone with PTT switch specifically designed
for mobile operation.
Impedance: 50 k® (MC-30S)
500 & (MC-35S)
= MICROPHONE MC-50
Unidirectional dynamic microphone with locking PTT switch
provides excellent performance for VOX operation.
Impedance: 50 k® and 6002 (switchable)
