SECTION 6 TROUBLESHOOTING
6-1 Introduction
This trouble shooting makes integral part of the Service Manual. And it has been prepared for the
persistent purpose of providing for repairing guidelines.
What has been described herein, moreover, is subject to the prerequisite for a repair to be made by
replacing a PCB.
6-2 Precautions
To prevent a new problem (seeondary disaster) from taking place in the proeess of trouble
shooting as described herein,every engineer concerned should duly take the following precautions:
1) Never remove any part from the electric system, including PCB, probe, cable, etc., before
powering off the equipment.
2) Do not proceed to a disassembly of equipment without observing the established disassembly
procedure. Be careful enough for wrongly disassembling the equipment would damage or
break it down.
3) To make certain of a voltage and/or a signal waveform, it is necessary to thoroughly know the
specification and handlmg procedure relating to a measuring instrument employed.
4) To ground a measuring instrument probe or the like, it is naturally necessary to know where a
signal to determine is grounded. Before using the instrument, moreover, make certain for
whieh the grounding terminal is intended,analog, digital, alternating current, direct current,
high voltage or low voltage.
I....................... I
| OCAUTIONO Failure to ground properly might result in an incapability ofobserving an |
| accuratevoltageor waveformor in a probabilityofburningoutthe |
I .... _measuring_-- --instrument---- or_ultrasound_-- --diagn°stic--_ equipment._-- --°r both._-- -- -- I
5) Do not fit a measuring instrument probe or the like to a measuring point before turning off the
ultrasound diagnostic equipment.
I I
OCAUTIONQ To determine an especially high voltage,it might rupture a circuit in
I I
the ultrasound diagnostic equipment. Besides, it might endanger a
I I
I_ _ engineer or engineers eoneemed. I

SECTION 7 ADJUSTMENT PROCEDURE
7-1 Introduction
The adjustment points shown in this adjustment procedure are points where the actual ultrasound
image is,directly adjusted.
7-2 Attention
In order to avoid some new trouble created by this adjustment procedure manual, the person
performing this adjustment should be restricted to someone who has undergone the Aloka approved
training course and who has a high level of technical expertise and knowledge.
Also, by ail means investigate beforehand whether the trouble you are attemptmg to solve by
adjustment is caused by faulty adjustment or by the failure of one of the circuits. Smce
indiscriminate readjustments can be a hindranee to restoring the equipment's original performance,
please exercise great caution in performing adjustments.
When aetually engaging in adjustments,be eareful espeeially in the following points.
1) Begin the operation only after switehing on the power and letting it warm up suffleiently.(30
minutes or more have passed after throwing the power switch ON.)
2) When adjusting variable resistors,do not exert greater force on the PCB than neeessary.
3) Some ofthe variable resistors used in S.M.T. (Surface Mount Technology) may be smaller in size
than those used in the past. When adjusting these devices, be sure to use a driver thatis
appropriate for each specific variable resistor.
4) Do not touch any variable resistor or any variable eoil, etc. whieh is not specifieally indieated in
these procedures. There is danger of altering the circuit to the pointwhere restoration of funetion
will become impossible.
7-3 Tools and Measuring Instruments
The tools and measuring instruments which are ordinarily necessary when perfonning
adjustments are as shown below.
1) Probe Convex : UST-9114-3.5
2) Driver : for +M3

SECTION 8 PERFORMANCE CHECK
8-1 Introduction
"Performance Check" describes the items to be confirmed for the maintenance of an equipment
quality and safety under the circumstances referred to below.
•Once a repair work has been donc,
• Once an improvement, for a problem or the like,has been made,
• Once a change as to upgrade the functions and/or specifications has been made,
• When a periodic inspection is made.
8-2 Precautions
Unless otherwise specified, this performance check must be conducted with ail coverings attached
in place and under the following environments:
• 30 minutes or more have passed after throwing the power switch ON.
If the performance check specified herein should be condueted after a repair,an improvement or
an upgrade, make certain of the following:
•Ail the PCBs removed are reconnected properly.
• Ai1 the connectors removed are reconnected properly.
• The replaced ROM and others are mounted in place on a printed circuit board.
The power pin, in particular, should never be mistaken for the GND pin.
• The unnecessary ROM is not left behind inside the equipment.
• Tool, measuring probe,and the like are not left behind inside the equipment.
• Optional components and grounding cable are properly reconnected.
• Screws and the like are not left behind inside the equipment.
8-3 Making Entries in Repair Report
Upon completion of the check, enter findings thereof in such a form as repair report or the like.
And present it to the user. Keep a copy thereof in custody.
