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

As of November 2001, Canon is responding to a wide range of customer demands with the six series in our line:

the single-lens-reflex EOS 1D and EOS D30, the PowerShot Pro90 IS with 10x zoom lens, the PowerShot G2

with high image quality and advanced features, the highly compact PowerShot S40/S30, the ultra compact IXY

DIGITAL 300/200 and the basic value PowerShot A20/A10.

However, as digital cameras are proliferating rapidly recently, we believe there are many potential consumers

who want to enjoy the convenience of digital photography, but who consider the $300 to $400 class such as the

PowerShot A20/A10 too expensive, and ‘toy’ cameras in the $100 and under class to be inadequate. We there-

fore believe that we can enhance our market share by providing a low-end Canon digital camera for these

consumers, and we are undertaking development of new digital cameras to respond to these demands.

This means that first-time users of digital cameras, and those who mainly want ease of use, are the main targets

for the low-end class (2-megapixel) PowerShot A200 and (1.3-megapixel) PowerShot A100, which will be

distinguished from other brands by a combination of high-end features such as primary filters plus a new image

engine, movie recording and Camera Direct features, and basic features such as a fixed-focus lens and simple

operation aimed at this class of users.

1-2 Product Concept

Because these models are aimed at users purchasing a digital camera for the first time, who want to enjoy

convenient digital photography economically, the PowerShot A200/A100 will be priced as low as possible, while

providing the same capabilities and features as higher-end models as much as possible. The product concept is

therefore “Excelling Classes of Advanced Features with Convenient Operation and High Image Quality with

High Grade Design.”

Also, despite the low price of the PowerShot A200/A100, we propose to foster a new culture of convenient

photo printing for the class of digital camera users who use a PC monitor or TV to display digital photographs, by

providing the Direct Print feature compatible with the CP-10 Card Photo Printer and the CP-100 Photo Printer,

to enable simple credit card or postcard size photo printing at home.
