Overview of this ECR
This ECR is a microprocessor-based system, using an 32-bits ARM Cortex-M3 microprocessor.
This service manual provides the technical information for many individual component systems, circuits and gives
an analysis of the operations performed by the circuits. If you need more technical information, please contact
our service branch or R&D center. Schematics and specifications provide the needed information for the
accurate troubleshooting.
All information in this manual is subject to change without prior notice. Therefore, you must check the
correspondence of your manual with your machine. No part of this manual may be copied or reproduced in any

Note: Before using this Electronic Cash Register (ECR) for the first time, leave it powered on in the REG
mode for at least 24 hours. This allows the MS Lithium battery, which maintains the memory of the
ECR while the power is off, to charge completely.
