SECTION 2 PRECAUTIONS
2-1 Precautions Against Electrical Hazards to Serviccman
When disassembling lhe equipmcnt after checking il for a trouble symptom, givc tare to the
ïollowing:
1) Be sure fo unplug the equipmcnt before disassembly.
2) Bc sure fo turn off the main switch on thc cquipmcnt whcn rcmcwing clcctrical paris such as
PCBs, probe, and table.
3) Safety alerl symbols
The indicaticm //_used on this equipment and in this service manual have the
following
meaning.
"Indicates apotentially hazardous situation which, if not avoided, may result in minor or
moderate injury.'"
"A caution message is inserted here. "
2-2 Prccautions Against Mcchanical Hazards to Scrviccman
When disassembling the equipment, give care fo the following fo prolect serviceman from
hazards :
1) Keep the working environment neat.
Wear working glcwes fo protect your hands from gelting injured by burrs on the unit and

-.
the Flow Chart and ils explanation show the lime when each section of service manual are required
on repair work. This is a guide for lhe usage of service manual.
The service manual is very important for the repair work, especially readjustment and
performance check al'ter completion of repair work. This is fo keep the safety and quality of
equipment. If you make them, you have fo describe thal the treatment has been done according fo
lhe applied section of service manual, on the repair report or the like.
The circled numbers shown in the Flow Charl on nexl page, are corresponded lo lhe procedure
number shown from page 3-3.

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.

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
