SAFETY SUMMARY
The following general safety precautions must be observed during all
phases of operation, service, and repair of this equipment. Failure
to comply with these precautions or with specific warnings elsewhere
in
this manual violates safety standards of design, manufacture, and
intended use of the equipment. Oansk Radio AS assumes no liability
for the customer's failure to comply with these requirements.
GROUND THE EQUIPMENT
To minimize shock hazard, the equipment chassis and cabinet must be
connected to an electrical ground. The equipment is equipped with a
three-conductor ac
power socket. The power cable must either be plug-
ged into an approved three-contact electrical outlet or used with a
three-contact to two-contact adapter with the grounding wire {green)
firmly connected
to an electrical ground (safety ground) at the po-
wer outlet.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the equipment in the presence of flammable gases or fu-
mes. Operation of any electrical equipment in such an environment con-
stitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must not remove equipment covers. Component repla-
cement and internal adjustments must be made by qualified maintenance
personnel.
Do not replace components with power cable connected. Under
certain conditions, dangerous voltages may exist even with the power
cable removed. To avoid injuries, always disconnect power and dischar-
ge circuits before touching them.

SAFETY SUMMARY (continued)
DO NOT SERVICE OR ADJUST ALONE
Do not attempt internal service or adjustment unless another person,
capable
of rendering first aid and resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY EQUIPMENT
Because of the danger of introducing additional hazards, do not in-
stall substitute parts or perform any unauthorized modification to
the equipment.
DANGEROUS PROCEDURE WARNINGS
Warnings, such as the example below, precede potentially dangerous
procedures throughout
this manual. Instructions contained in the warn-
ings must
be follm'led.
WARNING I
Dangerous voltages, capable of causing death, are present in

1.1 Introduction
SECTION 1
GENERAL INFORMATION
This Operating and Service Manual contains information required
to install, operate, test, adjust and service the TU4015.
Specifications are listed in paragraph 1.6.
These specifications are the performance standards or limits
against which the TU4015 is tested.
Due to experience obtained from the production and operation of
the equipment, minor differences between the TU4015 and the
manual may occur.
Wherever
possible such differences are dealt with in Section 7
11
MANUAL CHANGES ...
The electrical modules of the TU4015 are listed in Section 6.
1.2 Safety Considerations
This
manual contains information,
must
be followed to ensure safe
TU4015 in a safe condition.
1.3 Description
cautions and warnings which
operation and to maintain the
The TU4015 is a fast antenna tuner for shipboard use. The control
of the tuner is carried out by means of a serial data bus from a
SE4010, an exciter located in the transmitter.
The serial data bus is compatibel with RS485, strappable between
1200, 2400, 4800 and 9600 bps, with a maximum distance between
the
exciter and the antenna tuner of 150 meters.
The TU4015 is configured as a L matching circuit with a lowpass
characteristic. The inductors and capacitors are discrete binary
weighted elements switched
by high speed reed relays.
The TU4015 incorporates a dummy load used for transmitter tests
as well as tuning.
The housing of the tuner is especially designed for a low thermal
resistance which combined with the temperature controlled forced
air circulation and temperature supervisors ensures a low stress-
ing of the components in the tuner.
