SAFETY PRECAUTIONS
The following precautions should be observed when servicing.
1. Since many parts in the unit have special safety-related characteristics, always use genuine CANON replacement parts.
Especially critical parts in the power circuit block should not be replaced with other makes.
Critical parts are marked with !in the schematic diagrams.
2. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged
by the short circuit.
3. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
4. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
4-1 Leakage Current Cold Check
1) Unplug the AC cord and connect a jumper between the two prongs on the plug.
2) Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part
on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to
the chassis, the reading should be between 1MΩand 5.2MΩ. When the exposed metal does not have a return path to the
chassis, the reading must be ∞.
4-2 Leakage Current Hot Check
1) Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2) Connect a 1.5KΩ10 watt resistor, paralleled by 0.15µF capacitor, between each exposed metallic parts on the unit and a
good earth ground such as a water pipe, as shown in the figure below.
3) Use an AC voltmeter, with 1000Ω/volt or more sensitivity, to measure the potential across the resistor.
4) Check all exposed metallic parts of the cover (Cable connection, Handle bracket, metallic cabinet.
Screwheads, Metallic overlays, etc), and measure the voltage at each point.
5) Reverse the AC plug in the AC outlet and repeat each of the above measurements.
6) The potential at any point should not exceed 0.75V RMS.
A leakage current tester (FLUKE MODEL : 8000A equivalent) may be used to make the hot checks.
Leakage current must not exceed 0.5 milliamp.
In case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and corrective action must
be taken before returning the instrument to the customer.

1 Development Background
1-1 Development Objectives
Beginning with the ultra compact 2-megapixel 3x zoom IXY DIGITAL 300 introduced in Spring 2001, followed
in succession by the PowerShot A20/A10 and IXY DIGITAL 200, all four models adopted primary color filters
and the new image engine which provides exceptional color reproduction, and have received high acclaim for
their image quality.
Even the PowerShot A20/A10 has a friendly design intended for a wide range of users, but they are especially
suited to general use because of the high image quality and advanced functions exceptional for their class, and
support for the popular AA-size batteries, which have resulted in very good sales. The PowerShot A20/A10 is
a product for which high-volume sales can be expected, because of the positioning in the mid-price range, so
continuing to maintain a stable share in the market for this class of camera is indispensible to the business
strategy.
The PowerShot A40, with the same basic capabilities as the PowerShot A20, also incorporates advanced
photographic features provided with the PowerShot G2 and PowerShot S40/S30, and further evolves the design
so the above objectives can be achieved with a digital camera having even greater imaging capabilities for the
price. Furthermore, to target those users looking to pay a lower price, the PowerShot A30 with a 1.3-megapixel-
grade CCD (active camera component pixels) will be manufactured as a successor to the PowerShot A10.
1-2 Product Concept
The PowerShot A40/A30 is intended as successor to the basic product concepts of the PowerShot A20/A10,
targeting the first-time digital camera user looking to simply enjoy a digital camera or to minimize expense. Our
design idea is to provide enhanced functionality through the theme of More Basics & Value, by providing “high
image quality,” “advanced features with comfortable operation” rounded out with “conservative design” and
“system accessories and software” as the product concepts.
Also, to promote a new culture of simple printing for digital camera users, the PowerShot A20/A10 supports
the so called Camera Direct {{Direct Print?}} feature that provides easy printing with the CP-10 Card Photo
Printer. The PowerShot A40/A30 will continue the same support, and also be compatible with the CP-100
Photo Printer now under development, which supports A6-size printing for credit-card to postcard size prints.
More Basic & Value
- Movie function with Audio
- Capability of manual functions
- Upgrade for photographing features
- Suport for “new photo-printer”
