Overview of this ECR
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

Note: Before using this Electronic Cash Register (ECR) for the first time, leave it powered on in the REG mode for

power is off, to charge completely.
